ObjectivesAnalyze the influence of Binge Eating Disorder (BED) and symptoms of depression and anxiety on anthropometric and body composition changes over five years after bariatric surgery in patients with obesity.MethodsEvaluation of 118 individuals undergoing bariatric surgery, divided into two groups: Group 1: individuals with BED; Group 2: individuals without BED. The individuals were submitted to anthropometric and body composition evaluation, and analysis of the presence of BED, depression, and anxiety according to the DSM-V and using validated questionnaires. The Kolmogorovi-Smirnov, t-test, Fisher’s, chi-square, and ANOVA were used for statistical analysis.ResultsThe groups with BED (N=61, 51,7%) and without BED (N=57, 48,3%) did not differ from each other for all sociodemographic assessed variables (p>0.05) and had similar changes in waist circumference and body composition over five years after bariatric surgery (p>0.05). On the other hand, only patients with BED had severe depression (13,11%, p=0.0079) and had a higher frequency of moderate (22.95%, p=0.0022) and severe (14.75%, p=0.0022) anxiety in the preoperative period of bariatric surgery. In addition, only the group with BED had increased weight and increased BMI in the fifth year after bariatric surgery (p<0.05).ConclusionPatients with BED had more intense symptoms of depression and anxiety, and this disorder may reappear in the postoperative period of bariatric surgery and contribute to weight gain and an increase in BMI.Level of evidence: III (evidence obtained from case-control analytic study).

Numerous animal models have been developed and have contributed to the exploration of the pathology of diseases and development of new drug therapies. Memory is the ability to record, retain and recall the data or event of life whenever needed. In the last years, the increasing number of neurological disorders raise a concern, for this, various investigations have been done to postulate the basic mechanisms and signalling molecules and steps involved in the process of the formation of memory and learning. Various neurotoxins have been utilized as an experimental model to study and develop new pathways and specific targets to treat the disorders, but none of them are able to predict all the characteristic features that are involved in the alteration of memory. Toxins being utilized for the different experimental models include scopolamine, ethanol, domoic acid, streptozotocin, okadaic acid, quinolinic acid, paraquat, rotenone, MPTP, methamphetamine, etc. The current study summarizes the toxins from a different sources that could support the investigation to explore the pathology and to develop the target drug delivery for memory impairment, impaired neurodevelopment, diminished intellectual power, and other cognitive disorders like AD, PD, HD, etc.

En la actualidad los pacientes con enfermedad renal aguda son manejados con hemodialisis obteniendo buen pronostico, en algunos centros hospitalarios donde no se cuenta con los insumos y el personal capacitado para su manejo y seguimiento se implementa la dialisis peritoneal obteniendose resultados favorables en los pacientes con enfermedad por coronavirus-19 y que la funcion renal se ve comprometida se han implantado ambos tratamientos, sin embargo en muchos centros hospitalarios esta pandemia rebaso su capacidad de cobertura generando con ello la implementacion de abordajes de repuesta rapida. En el Centro Medico Navalse implemento el uso de hemodialisis en estos pacientes de un total de 58 pacientes evaluados entre los meses de abril a septiembre del 2020, 42 recibieron terapia de reemplazo renal a razon de hemodialisis y 13 pacientes dialisis peritoneal, de los cuales 40 y 11 fallecieron respectivamente, arrojando un tasa de mortalidad de acuerdo al procedimiento de 95.23% y 84.61% esto puede deberse al numero de pacientes que recibieron cada uno de los procedimientos, sin tener que estigmatizar que un abordaje es mejor que otro puesto que existe un compromiso ventilatorio previo al daÃƒÂ±o renal que favorece el estado proinflamatorio del paciente repercutiendo en la funcion renal y por ello en la terapia que se implementa como reemplazo.Con los resultados obtenidos en la presente investigacion se puede concluir que el tipo de terapia de remplazo renal no esta relacionado con la mortalidad de dichos pacientes, esta puede deberse al proceso inflamatorio sistemico ocasionado a la neumonia por COVID-19, ya que dentro de las variables analizadas que mostraron una relacion estadisticamente significativa se encuentra los dias en el retraso del manejo hospitalario (para la infeccion por COVID-19), un mayor puntaje en la escala de SOFA, dicha escala nos evalua el riego del paciente de presentar disfuncion multiorganica y finalmente la distensibilidad pulmonar, donde establecemos que a menor porcentaje mayor es el grado de compromiso ventilatorio del paciente, pudiendo favorecer con ello estados proinflamatorios severos y compromiso en el metabolismo celular, aunado a las comorbilidades que el paciente pueda presentar como la diabetes tipo II incrementan el riesgo de mortalidad, siendo esta independiente del tipo de manejo que se requiera para sustituir la funcion renal sin embargo si podemos establecer que aquellos pacientes que son tratados con hemodialisis tiene una sobrevida mayor que los pacientes que reciben dialisisperitoneal o terapia dual (dialisis peritoneal /hemodialisis).
Nonlinear effect of female board directorship on bank financial soundness
Authors: Thanh Binh Nguyen T.
Published: October 2021

To verify if female directors on the bank’s board play a role in managing bank stability, this paper applies a multi-threshold model to quarterly data from 26 Taiwanese commercial banks over the 2002–2018 period to find the factors that influence bank financial stability and to examine how female board directorship affects it. The empirical results suggest that women on the board do play a guarding role in a bank’s financial soundness when banks reach a high debt ratio regime. The influence of female directors on the capital adequacy ratio is positive for banks with a debt ratio higher than 92.69%, and for non-performing loans it is positive within the regime of the debt ratio 90.71% ≤ τ < 95.39%.In particular, it has been found that the value of total assets is a factor that positively affects a bank’s financial soundness, which supports the “too big to fail” theory for banks with high total assets and debt ratios. Revenue has the opposite effect on financial soundness when it negatively affects the capital adequacy ratio and positively affects non-performing loans. A larger board size reduces banks’ financial soundness, which is contrary to the higher proportion of women on the board of directors, which generally contributes to the financial stability of the bank.
January anomalies on CEE stock markets
Authors: Árendáš Peter , Chovancová Božena , Kotlebova Jana , Koren Martin
Published: October 2021

Numerous studies show that stock markets are often impacted by various calendar anomalies that disrupt the “random walk” behavior of stock prices. These anomalies contradict the Efficient markets theory and can be exploited to generate abnormal returns. This paper investigates the presence of two of them, namely the January effect and the January barometer, on the stock markets of 12 Central and Eastern European (CEE) countries. The paper examines the statistical significance of differences in returns recorded over the month of January and returns recorded over the other months (the January effect), as well as the statistical significance of differences between returns recorded during the remainder of year after a positive January return and after a negative January return (the January barometer). The results show, among other things, that the statistically significant January effect affects the Estonian, Lithuanian, Czech, Romanian, and Latvian stock markets. On the Romanian and Lithuanian stock markets, statistically significantly higher January returns are accompanied by statistically significantly higher January price volatility. On the other hand, we can speak of a statistically significant January barometer only in the case of the Latvian, Lithuanian, and Ukrainian stock markets. The presence of these anomalies is contrary to the Efficient market theory. It can be assumed that proper investment strategies based on these calendar anomalies should be able to generate abnormal returns.

The impact of the water commonweal propaganda on citizens' water-saving behavior: the intermediary role of propaganda channels and forms – evidence from China
Authors: Zhang Shujing , Fu Hao , Wang Yanrong
Published: October 2021

The water commonweal propaganda is an important measure to promote citizens’ water resource conservation and water-saving behavior. Based on Amos 21.0, this paper adopts structural equation models, through variable extraction and path construction, to explore the mechanisms of how water commonweal propaganda influences citizens' water-saving behavior. The research investigates the case of China's water commonweal propaganda. The results show that: (1) when the same propaganda forms and channels are adopted, the impact of different water commonweal propaganda content on citizens' water-saving behavior is significantly different; (2) with the same water commonweal propaganda content, different propaganda forms and channels have different impacts on citizens' water-saving behavior. Therefore, selecting appropriate propaganda forms and channels for the water commonweal propaganda can significantly improve their impact on citizens' water-saving behaviors. The research aims to provide theoretical support and practical basis for China's follow-up water commonweal propaganda.

Modern politicians differ significantly in their characteristics from those of past years, however, the basic characteristics remain the same.
FEATURES OF THE TRANSMISSION OF PUNCTUATION MARKS IN THE TRANSLATION OF POETIC TEXTS FROM RUSSIAN INTO FRENCH
Authors:   Astrakhan State University, MARINA I. SVESHNIKOVA , ELENA I. SERNOVA ,   Astrakhan State University
Published: October 2021

The article is devoted to the problem of punctuation transmission in poetic translation. Punctuation helps to understand the written form of the text. The structure, meaning, and intonation of the utterance dictate the setting of the necessary punctuation mark. In poetic works, punctuation also serves the purpose of highlighting or emphasizing the most significant elements. The search for adequate means of conveying intonation and highlighting semantic segments leads to a combination of various additional ways of formatting the text. The individual style of a writer or poet in a literary text is conveyed through stylistically significant marks of the author's punctuation. The translator must decide whether to keep the author's punctuation, omit it, or include the punctuation marks of the receiving language in the translation. Poetic translation often leads to a significant rearrangement of the text, in which the punctuation component refers to other speech segments than in the original text, what was shown by the example of translations of I. Bunin's poetic works.

To make a decision on the serial production of anti-aircraft guided missiles, it is necessary to perform a whole range of work ranging from the development of a technical task for the design, manufacture and testing of the finished product. In the final stage of testing at the test site, the anti-aircraft missile is undergoing dynamic tests in accordance with the state test program. For testing at the test site, in addition to on-site tests of missiles using targets to defeat them, various stands and simulators are used, as well as mathematical simulations in cases where inkind tests for some reasons, for example, in order not to incur losses, become impossible, as the prototype of the product submitted for testing can be in a single instance or its application can bring huge destruction to the environment. The article presents the development of an important component of the main stage of the study - the mutual influence of elements of the steering tract and panels of the rudders during dynamic tests of anti-aircraft guided missiles. The results of the work on mathematical and simulation modeling are presented.

Published: October 2021

The aim of the study is to develop information systems for supporting and supporting decision-making in the production of a metal oxide catalyst that provides targeted synthesis of carbon nanotubes by gas-phase chemical deposition. To achieve the goal, the following tasks were solved: a new approach to the process of creating a catalyst for the thermal decomposition of unstable compounds for synthetic nanotubes was developed; experimental studies of the effect on the post-thermal treatment of the catalyst and its precursors by physical action (ultrasonic, electromagnetic and microwave fields, etc.), which were obtained the approximating characteristics of the synthesized models of carbon nanostructures on the parameters of the process of pre- and post-thermal treatment of the catalyst were used to create a recommendation module. On the basis of the results obtained, blocks of implementation and technologies were developed, used in the creation of a system for maintaining and supporting solutions for the production of a catalyst for synthetic nanotubes. The application of the developed system of maintenance and support of decisions makes it possible to form a catalyst that makes it possible to synthesize carbon nanotubes with specified characteristics. Also, the use of this information system in the production of a catalyst helps to expand the range of synthesized nanoproducts in the process of gas-phase chemical deposition without changing the composition of the catalyst.

Published: October 2021

In the modern world, video files play a special role. The development of video compression algorithms and the growth of the Internet’s capabilities make it possible to transfer video files. Damage inevitably occurs when transferring video files. Accordingly, the question arises about restoring a damaged file and obtaining information from it. The article discusses the most commonly used video file extensions AVI, MP4. As a result of the study, it was revealed that the most common damage is in the headers, which leads to errors when opening files by players, data is damaged less often. Data corruption leads to the fact that a certain fragment of the video file is either played with errors, distortions, or is skipped. The article discusses the possibility of recovering damaged video file using the removal of undistorted data and proposes an algorithm for analyzing frames using a neural network. As part of the algorithm, a neural network is used to identify damaged frames in video data. The algorithm was implemented as a software product. For the first stage of checking the efficiency of the algorithm, deliberate distortions of one frame were made for each video file under study. As a result of experimental verification of the developed algorithm, it was revealed that it provides high accuracy in detecting distorted frame sequences.

Published: October 2021

An important problem of choosing a method for synthesizing regulators for constructing a system for controlling the parameters of hydrolithospheric processes is considered. The article deals with the issues of system analysis and synthesis of control systems with distributed parameters. The existing ways of solving mathematical equations describing models with spatial coordinates are shown. The main methods when there are solutions to the mathematical model are identified: analytical construction of optimal regulators and the structural method of analysis. Methods of approximation in cases where there is no solution to the mathematical model are described: methods of finite-dimensional approximation; decomposition of bilinear control systems; frequency method. The main provisions of the methods for solving the problem of discretization in partial derivatives are given. The preference of the frequency method of regulator synthesis in the creation of control systems for hydrolithospheric processes is shown. A hodograph is obtained in the form of logarithmic amplitude and phase frequency surfaces, which can be used to interpret the Nyquist stability criterion from graphs. A frequency method for the synthesis of multidimensional systems is considered, when the input effects to a distributed controller are implemented as a discrete function in space. The condition under which the object belongs to the class of spatially invariant objects is shown. It is concluded that the frequency method of regulator synthesis is the most convenient tool for creating systems with distributed parameters.

Published: October 2021

Since importance of improving of Intelligent Transportation System (ITS) always follow modern trends by using new wireless communication technologies, the trend of latest research topics is focusing on Vehicular Ad Hoc Network (VANET). VANET networks play a vital role in ITS due to their increasing importance for the building of ITS. VANET is a subclass of mobile ad-hoc networks (MANET). VANET depends on wireless technologies to establish communication between moving vehicles (nodes). An appropriate and efficient routing protocol helps to successful exchange data between mobility nodes in vehicular ad-hoc networks. VANET has a lot of similar features to MANETs such as finite bandwidth, self-arrangement, self-administration, and unstable network topology. Except it has some important features of its characteristic such as very high node mobility, delay restrictions, and frequent network outages. For this reason, routing in VANET networks is much more complex than routing in MANET networks. The purpose of this study - to evaluate the performance of protocols AODV (Ad hoc On-Demand Distance Vector) and DSR (Dynamic Source Routing) and their impact on the performance of networks VANET. This paper differs in that it analyses the impact of network size at a large number of nodes, and different vehicle speeds on network performance metrics like packet delivery ratio, throughput, average delay, overhead and packet loss ratio and assessing the level of network performance at realistic mobility scenarios for the movement of vehicles in the street generated by Bonnmotion tool. Also, the simulation is carried out in NS-3 simulator to create VANET network topology and routing protocols.

Published: October 2021

The general geological foundations of oil and gas zoning are laid down by Russian and foreign researchers and are carried out according to different principles, which reflects the ambiguity of many researchers ' views on the genetic aspects, the mechanism of formation of oil and gas accumulations, and other issues of oil geology. The development of a sedimentary basin and its transformation into an oil and gas basin is accompanied by complex and long-term intermittent-continuous processes determined by tectonic laws that control the formation of platform, geosynclinal and oceanic structural elements of the earth's crust, within which these basins are located. The zoning scheme is based on a complex of various geological indicators that determine the time and conditions for the generation, migration, accumulation and preservation of hydrocarbon accumulations. When comparing the Russian and international schemes of regional studies, it becomes obvious that the essence of research does not change either in the domestic scheme or in the Western classification.

Published: October 2021

Hydrogeological conditions of reservoir waters of oil and gas fields in the northern water area of the Caspian Sea characterize the geological features of the structure of the Northern Caspian shelf, as well as the thermodynamic parameters of the exploitation of productive deposits, production and transportation of oil and gas. Reservoir waters contain water-soluble gases. According to the size of mineralization, the ratio of the main components of the salt composition, as well as the presence of iodine and bromine, reservoir waters can be attributed to a relatively "young" genetic age, subject to secondary geochemical processes of changing the salt composition in interaction with "secondary" migrated hydrocarbons. The physical and chemical properties of reservoir waters are determined by PVT analysis technologies. Hydrogeological and geochemical studies of compatibility with reservoir waters of marine waters injected to maintain reservoir pressures (PPD) during the development of offshore fields in order to increase the oil recovery coefficient (KIN) indicate the absence of colmating secondary sedimentation in mixtures of natural and man-made waters.

Published: October 2021

Anthropogenic and technogenic processes in the urban environment significantly change the chemical composition of the soil cover. One of such processes influencing the state of the urban soil is the process of soil cover pollution with heavy metals. Heavy metals are biochemically active and highly toxic; they are found in various components of the natural environment, as well as in systems of anthropogenic and technogenic origin. They have the property of accumulation in the body of living beings and have a negative effect on their condition. This group of chemical elements includes lead, zinc, chromium, mercury, copper, iron and other metals. Exceeding the permissible concentration of heavy metals in the soil of an urbanized area and their toxic effects pose a significant danger to humans. Contamination of the soil cover of an urbanized area with heavy metals is associated with the impact of a large number of sources of anthropogenic and technogenic origin, namely, energy and industrial facilities, city infrastructure support systems, zones of construction activities and storage of materials or waste. One of the main highly toxic chemical pollutants of the soil cover of the urbanized territory belonging to the group of heavy metals is zinc «Zincum-Zn». The article describes the results of a 2020 study of the current zinc content in the soil cover of the city of Astrakhan. The relevance of the work lies in the geochemical analysis of the content of heavy metals in the soil of the city of Astrakhan. The aim of the work was to study the modern process of soil contamination of the city of Astrakhan with zinc. The work was based on the task of determining the degree of exceeding the hygienic standards of the maximum permissible concentration of zinc in soil samples. Methods of geographical and ecological research were used in the work, soil samples were collected, followed by determination of the concentration of a substance in each of the soil samples in a certified laboratory. In the course of the work, the indicators of exceeding the maximum permissible concentration of zinc in the soil of the city of Astrakhan were determined and the presumptive sources of pollution were identified.

At the same time, it poses a severe threat in various ways to the status quo of the existing regime of space regulation. Taking humans to outer space as a passenger aﬀects the current social, psychological, political, and legal setup. The paper highlights the legal issues that are arising from commercial human spaceflights. Therefore, in section one, the article discusses applicable international law to this emerging activities. Part two details speciﬁcally on the international space law that is relevant to regulate these activities. After analyzing the existing international law on space activities in sections one and two, which are essential for the commercial human spaceﬂights, part three identiﬁes several legal challenges that are not suﬃciently addressed by the existing laws. Section four examines the role played by the regulatory organization to develop the space law, and the role of the International Civil Aviation Organisation (ICAO) has been discussed in detail. As the ICAO holds good experience in handling air transportation, many believe that the ICAO is naturally well placed to regulate commercial space transportation. This aspect has been elaborated in detail in this part. In the ﬁfth, i.e. the last section, the authors conclude by arguing to develop a new international convention to regulate it.

Published: October 2021

On the basis of comparative law, this paper analyzes the issues of national minorities in three BRICS member-states (Brazil, India and Russia), and considers the directions and trends of the constitutionalization of national minority rights in these states. The authors argue that the coordination of the interests of industrial companies, regional communities and national minorities, alongside the establishment of common standards between BRICS are vital in order to ensure the sustainable growth of the economies of its member-states. The main comparison criteria are as follows: the understanding of the term “national minority” in diﬀerent jurisdictions; the delimitation of powers of federative and regional authorities; a list of national minority rights; and instruments of representation and legal protection of national minorities. In regards to Brazil, this article focuses on the impact of the historic concept of racial democracy on contemporary policy on the issues of national minorities. For India the focus is on case law of the Supreme Court on minority issues, and for Russia the focus is on the protection of indigenous “small-numbered” peoples. The authors conclude that the direction of the constitutionalization of national minority rights diﬀers dramatically in Brazil, India and Russia. Therefore, it is necessary to provide a common understanding of the purpose of such constitutionalization, which is namely, to preserve the identity of such minorities in the process of their gradual involvement in modern economic structures and national processes.

In modern conditions of economic instability in various sectors of industry for the national economic complex, it is important to improve the technology for repairing parts of power units, while the development of modern technological methods for restoring the contact surfaces of parts should be carried out in the conditions of enterprises and be accessible. The article compares the most common methods of surface parts restoration, such as flame, plasma spraying and electric arc surfacing. Studied experience of various specialists working in this direction made it possible to implement these reduction methods using a charge based on a mineral tungsten-containing concentrate, boron and carbon. The process of alloying the resulting coatings was investigated, where tungsten is in the form of tungsten trioxide (WO3) and calcium tungstate (CaWO4). A comparative analysis of the methods for restoring the surface of the exhaust valve cone of the D49 diesel engine has been carried out. The article presents results of microand macroanalysis of the structures of the obtained coatings and the base metal of the restored part, the results of the analysis of the chemical composition, the evaluation of the microhardness and adhesive strength of the adhesion of the obtained coatings to the surface of the base metal. Authors substantiated the prospect of applying the methods of gas-thermal restoration of the surface of parts in relation to the method of electric arc surfacing. Subsequent studies will focus on the installation of remanufactured parts in the internal combustion engine of the locomotive, their operation in real conditions, and the assessment of reliability and durability. Research in this direction will improve the quality indicators of the restored surfaces of power unit parts of rolling stock.
Rational reconstruction of sectioning posts of AC catenary at disconnectors

Published: October 2021

Operation of sectioning posts of the AC catenary at the disconnectors on the Gorkovskaya railway for a period of more than 60 years has shown its reliable operation, and the maintenance was reduced to a minimum. However, due to the growth of heavy haul and high-speed traffic on a number of sections, their reconstruction was required. In accordance with the current regulatory documents, such a reconstruction provides for the transfer of the operation of sectioning posts from disconnectors to circuit breakers. In connection with the reliable operation of the sectioning posts on disconnectors and the simplicity of their maintenance, it is proposed to expand the options for the reconstruction of the sectioning posts on the disconnectors and to introduce three reconstruction options into the regulatory documents. The first option provides for the reconstruction of the sectioning post with disconnectors by transferring it to the classic scheme with four switches, as indicated in the current regulatory documents. The second option provides for leaving the sectioning post at the disconnectors, but adding a fast-acting automatic reclosing device in the inter-substation zone in case of passing short circuits. The third option provides for the reconstruction of the sectioning post on disconnectors with the introduction of a vacuum circuit breaker into the bus of the post and a device for high-speed automatic reclosing and opening of the disconnector, in the zone of which a short circuit has occurred. The schemes of automatic devices for determining a stable (passing) short circuit in a traction network and a device for determining the location of damage are considered. The operation of the sectioning posts, reconstructed according to the indicated options, has been tested practically at the existing sections of the power supply of the traction network of the Gorkovskaya railway. All of them have shown high reliability.
Formation of performance indicators of railway transport for calculating labor productivity
Authors: Miroshnichenko O. F. , Oginskaya A. E.
Published: October 2021

Labor productivity in railway transport is determined using the “reduced performance” indicator, which is formed using a reduction factor designed to take into account the difference in unit costs of the payroll fund when performing a unit of work performance: ton-kilometers in freight traffic and passenger-kilometers in passenger traffic. The article reflects the results of a study to determine the value of the passenger turnover reduction factor in the formation of the total transportation performance of Russian Railways in modern conditions. The relevance of the revision of the current reduction factor is due to a change in the organizational structure as a result of the reform of railway transport, an increase in costs per unit of production by improving the quality of passenger traffic, strengthening security measures at stations and platforms, development of electronic passenger information systems, a significant increase in the volume of high-cost types of high-speed and high-speed passenger transportation.A comparative analysis of the costs of the payroll fund in passenger and freight traffic in the context of tariff components is carried out. The comparison was carried out both in general and differentially for each type of activity carried out by the company in the passenger complex, namely: the provision of services for long-distance and suburban passenger transportation, long-distance passenger transportation and suburban traffic, carried out in high-speed rolling stock. The most costly items in each facility were identified, which characterize the labor intensity by type of activity of Russian Railways. For calculating the labor productivity of the company's employees, proposals have been developed for the formation of the reduced freight turnover using a single coefficient for passenger turnover, equal to 3.7.

Published: October 2021

Antecedentes y Objetivos: Hymenochaete es el género con el mayor número de especies de la familia Hymenochaetaceae en México, teniendo registradas 25 especies. Se caracteriza por su basidioma principalmente resupinado, aunque puede ser pileado o estipitado, de colores pardos, con presencia de setas y reacción xantocroide. El presente estudio tiene por objetivo describir una nueva especie de Hymenochaete.Métodos: Los materiales estudiados en fresco se describieron macro y micro morfológicamente usando microscopio estereoscópico y óptico, y tomando fotos in situ. Se revisaron ejemplares de los herbarios ENCB y FCME, así como literatura especializada para su descripción.Resultados clave: Hymenochaete liliae sp. nov. se caracteriza por el basidioma resupinado, adnato, carnoso, himenóforo liso, con numerosas setas, margen determinado, abrupto, con sistema hifal monomítico, septos simples; setas subfusiformes, abundantes en el himenio, 69-80 × 6-8 µm, agudas, con cristales y basidiosporas elipsoides, de paredes delgadas, 5-8 × 2-3 µm. Aunque se asemeja a H. rhabarbarina, se diferencia por presentar setas cubiertas con cristales y esporas de 4.8-6 × 2.3-3.3 µm. También se podría confundir con H. minuscula por su color del basidioma; sin embargo, las setas son de menor tamaño (40-60 µm), así como los basidios (15-20 µm). Se separa de H. cinnamomea por no presentar un basidioma estratoso, setas con cristales, de 69-80 × 6-8 µm, basidiosporas de 5-8 × 2-3 µm, elipsoidales.Conclusiones: Se propone Hymenochaete liliae como una especie nueva, que se distribuye en el bosque tropical del estado de Oaxaca, y hasta la fecha solo reportada de la localidad tipo.
