title: Three interesting fungi from American bullfrog larvae (Rana catesbeiana) in Yunnan, China

description: This dataset contains the digitized treatments in Plazi based on the original journal article Yang, Erfu, Lu, Wenhua, Tibpromma, Saowaluck, Dai, Dongqin, Gao, Ying, Promputtha, Itthayakorn, Karunarathna, Samantha C. (2023): Three interesting fungi from American bullfrog larvae (Rana catesbeiana) in Yunnan, China. Phytotaxa 587 (3): 251-268, DOI: 10.11646/phytotaxa.587.3.4, URL: http://dx.doi.org/10.11646/phytotaxa.587.3.4AbstractAmerican bullfrog (Rana catesbeiana) is an alien invasive species in southwest China native to the central and eastern United States and southeastern Canada. After the 19 th century, they extensively appear in aquaculture and natural environments worldwide as a delicious food but also creating a serious threat to the survival and development of native species. In the early rainy season, dead American bullfrog larvae floating on the water of unnamed ponds in Qujing Normal University, Yunnan Province, China were collected and brought to the mycology laboratory, and three interesting fungal strains were isolated from their intestinal contents. Phylogenetic analyses were carried out on the resultant isolates based on multiple gene sequences (ITS, LSU, rpb2, tub2, tef1-α), and results confirmed that the three strains belong to three species, namely; Boothiella tetraspora, Sordaria macrospora and Trichoderma virens. The morphological characteristics were also used to describe the fungal taxa. Photographic plates, descriptions, and phylogenetic trees that show the placements of the fungal species are reported herein.

title: Green synthesis of hierarchical NaY zeolite for efficient Knoevenagel condensation
title: 等级孔NaY分子筛的绿色合成及其催化Knoevenagel缩合反应

description: Hierarchical aluminum-rich zeolites show promising potential in the Knoevenagel condensation; however, their synthesis is hindered by high cost and energy consumption. To address this, a green synthetic route has been developed for preparing hierarchical NaY zeolite using submolten salt (SMS) activated perlite as the sole source of silicon and aluminum. Systematic characterization reveals that the NaY zeolite synthesized from SMS activated perlite exhibits high purity and crystallinity. This aluminum-rich NaY zeolite, with a framework SiO2/Al2O3 molar ratio of ca. 4.2, possesses intercrystalline mesopores, a large external surface, and abundant basic sites. Investigation of the crystallization process of this hierarchical NaY zeolite indicates that during the initial stage, small crystals assemble and grow on the surface of SMS activated perlite. As crystallization proceeds, the zeolite crystals rapidly grow and aggregate around the activated sample, ultimately forming a zeolite material with a crystal-packed morphology. In the Knoevenagel condensation of benzaldehyde with ethyl cyanoacetate, the synthesized hierarchical NaY zeolite demonstrates higher benzaldehyde conversion compared to conventional counterparts.

title: Emendation of Marcelleina Brumm., Korf & Rifai (Ascomycota, Pezizales) and proposal of Iodomarcelleina obscura gen. nov., sp. nov. and Scotopezia pseudoanthracina gen. nov., comb. nov. for the lineages outside it

description: This dataset contains the digitized treatments in Plazi based on the original journal article Sammut, Carmel, Alvarado, Pablo, Vooren, Nicolas Van (2023): Emendation of Marcelleina Brumm., Korf & Rifai (Ascomycota, Pezizales) and proposal of Iodomarcelleina obscura gen. nov., sp. nov. and Scotopezia pseudoanthracina gen. nov., comb. nov. for the lineages outside it. Cryptogamie, Mycologie 44 (12): 159-170, DOI: 10.5252/cryptogamie-mycologie2023v44a12, URL: https://sciencepress.mnhn.fr/sites/default/files/articles/pdf/mycologie2023v44a12.pdfABSTRACTIodomarcelleina obscura gen. nov., sp. nov. is described from Malta. This species is morphologically close to Marcelleina Brumm., Korf & Rifai but differs from species of this genus in the size and ornamentation of its ascospores and its amyloid asci, a taxonomic character lacking in species of Marcelleina. Ecologically I. obscura gen. nov., sp. nov. seems to prefer calcareous soils, fruiting in open sunny grounds as well as shaded areas. Genetically, it is nested in the Marcelleina - Ionopezia lineage of Pezizaceae Dumort., but outside of the Marcelleina s.str. clade. Scotopezia pseudoanthracina (Donadini) Van Vooren, Sammut & P.Alvarado, comb. nov., another species not supported within Marcelleina s.str., differs from I. obscura gen. nov., sp. nov. by its smaller and ornamented ascospores, as well as its genetic profile. Finally, the newly obtained data suggest that Marcelleina mediterranea Lantieri & Pfister is a synonym of M. tuberculispora K.Hansen & Sandal. As emended herein, the genus Marcelleina excludes species with amyloid asci.

title: Morphological and molecular insights into the hidden edible mushroom diversity in Sri Lanka

description: This dataset contains the digitized treatments in Plazi based on the original journal article Dasanthi, Naduni, Thambugala, Kasun M., Karunarathna, Samantha C., Ediriweera, Aseni, Munasinghe, Helani, Elgorban, Abdallah M., Harischandra, Hiruni, Dharmasena, Buddhika P. (2024): Morphological and molecular insights into the hidden edible mushroom diversity in Sri Lanka. Phytotaxa 645 (3): 192-213, DOI: 10.11646/phytotaxa.645.3.1, URL: http://dx.doi.org/10.11646/phytotaxa.645.3.1AbstractWith the increasing world population, identifying additional food sources is crucial. Mushrooms have long been considered a nutraceutical and are consumed globally, including in Sri Lanka. Due to its abundant biodiversity, there is a significant potential for diverse wild edible mushrooms in Sri Lanka. However, the identification of these mushrooms based on morphological characteristics can often be misleading. Molecular characterization ensures more accurate and reliable identification of mushrooms, yet it has not been conducted extensively in Sri Lanka. This study collected several wild edible mushroom samples from Colombo and Rathnapura Districts of Sri Lanka. The edibility of these wild edible mushrooms was confirmed based on traditional knowledge and later verified by published literature. Phylogenetic analyses based on maximum likelihood (ML) analyses of ITS rDNA sequence data and morphological characteristics were used to determine the identity of the collected mushrooms. In this study, six edible mushrooms, Calvatia candida, Pleurotus giganteus, Schizophyllum radiatum, Termitomyces heimii, T. microcarpus, and Volvariella volvacea were identified based on morphology and phylogeny. Calvatia candida and S. radiatum are reported as new records for Sri Lanka, while this is the first study conducted on molecular characterization of V. volvacea in Sri Lanka. Finally, this study aims to increase the research interest, cultivation, commercialization, and conservation of these identified edible mushrooms in Sri Lanka.

title: Advanced Ce-free radiation-resistant Er/Yb fiber with high laser efficiency and mechanism analysis
title: Advanced Ce-free radiation-resistant Er/Yb fiber with high laser efficiency and mechanism analysis

description: Radiation-resistant Er/Yb co-doped fibers (EYDFs) hold significant promise for space applications, where maintaining high laser performance under irradiation is a critical requirement. The widely used Ce-doping approach provides strong radiation resistance, yet it also degrades the intrinsic laser performance of the fiber. Moreover, Ce increases the core refractive index, which limits the allowable Er/Yb concentrations. In this work, we fabricate a Ce-free radiation-resistant polarization-maintaining EYDF with enhanced laser characteristics. The removal of Ce allows higher Er/Yb concentrations and increases the absorption coefficient, allowing shorter fiber lengths to be used in practical systems and reducing radiation-induced degradation. Under identical operating conditions, the novel fiber achieves a laser efficiency of 46.4%, compared with 38.9% for the Ce-doped fiber, while exhibiting comparable radiation resistance under the same X-ray irradiation environment. We further analyze the mechanisms of its laser performance and radiation resistance through radiation-induced absorption (RIA) measurements, transmission electron microscopy (TEM), and fluorescence lifetime characterization.

Cipola, to replace L. americanus Cipola & Bellini 2018, a combination preoccupied by Marlatt (1896). In addition to new geographic records for the species, two new species of Fractocyrtus are described: L. (Fractocyrtus) andensis sp. nov. from the Colombian Andes and L. (Fractocyrtus) chicomendesi sp. nov. from the Occidental Brazilian Amazon. The new species differs from other members of the subgenus in body color, dorsal chaetotaxy of the head, chaetotaxy of the third and fourth abdominal segment, postlabial chaetotaxy, trochanteral organ, collophore and furcula, beyond morphology on the lateral process of the labial papilla E. New patterns of body pseudopores are described and added to the new diagnosis for the subgenus. Fractocyrtus now has four species, with distribution from the Andes to the Oriental Brazilian Amazon.
