## Abstract

A first official taxonomic checklist of myxomycetes from the French department Aveyron is presented. As the result of data collected by the Mycological and Botanical Association of Aveyron (AMBA), literature and online research, a total of 21 species representing 14 genera, 7 families and 5 orders, were recorded. The following information for each taxon was reported: Latin name, author(s), Basionym, locality (if known) and record sources. Macrophotographs of some new records are also appended. This work is a contribution to the knowledge of myxomycetes of Aveyron, which will eventually be integrated into a national checklist project of French myxomycetes.

**Key words:** Biodiversity, inventory, taxonomy, Myxomycetes, Occitanie.

## Résumé

Une première contribution à la connaissance des Mycetozoa de l'Aveyron (France)

Une première liste officielle sur les Myxomycètes du département français de l'Aveyron est présentée. Au total, 21 espèces représentant 14 genres, 7 familles et 5 ordres, ont été listées, grâce aux données collectées par l'Association Mycologique et Botanique de l'Aveyron (AMBA) et à un travail de recherche bibliographique. Les informations suivantes pour chaque taxon ont été indiquées : nom latin, auteur(s), basionyme, localité (si connue) et les références. Des macrophotographies de quelques nouveaux taxa aveyronnais sont aussi annexées. Ce travail est une contribution à la connaissance des myxomycètes d'Aveyron, qui sera éventuellement intégré à un projet de checklist nationale des Myxomycètes de France.

**Mots clés :** Biodiversité, inventaire, taxonomie, Myxomycètes, Occitanie.

## Introduction

Myxogastria, also called myxomycetes, are single-celled eukaryotes that are characterized by the formation of a plasmode and usually associated with decaying plant material (Clavender 1995). They were initially included as fungi (lineage Myxomycota) mainly because of their phagotrophic nutrition mode and the production of fruiting bodies and dispersal by spores (Baba 2012; Sevindik & Akgul 2019). However, this grouping proved to be polyphyletic, including several independent protist lineages, none of them linked to the Fungi kingdom sensu stricto.

The traditional classification of myxomycetes was based on a combination of morphological characters, including fructification, appearance of the plasmodium and finally the fruiting body development. This traditional classification has undergone many changes over the years. It was initially based on the colour of the spore mass, the Amaurosporeae (dark-spored) and Lamprosporeae (bright-spored) (Rostafiński 1875). After many changes and new classification proposals (Massee 1892; Lister 1894, 1911; Macbride 1922; Lister 1925; Jahn 1928; Hagelstein 1944; Martin 1960), the classification of myxomycetes presented by Martin and Alexopoulos (1969), separating

myxomycetes into 5 major orders, has been accepted
worldwide and used even in recent articles (Poulain *et*
*al.*, 2011a, 2011b).

With the arrival of new molecular phylogeny
techniques, the group of myxomycetes was one
of the last to be studied with the expertise of this
technique (Leontyev et al., 2019). The classification
of myxomycetes is therefore changing, and requires
further studies in the coming years (Stephenson
2011; Fiore-Donno et al., 2012, 2013; Leontyev &
Schnittler 2017; Leontvey et al., 2019). The case of
myxomycetes has therefore not attracted much interest
from the non-specialist scientific community since the
first descriptions and monographs on myxomycetes.
A real need to study myxomycetes and revisit certain
genera and families exists, not least as the need to
know their biodiversity (Rollins & Stephenson 2011;
Stephenson et al., 2011; Novozhilov et al., 2017).

In addition to molecular methods such as meta-
barcoding (Feng & Schnittler 2016; Schnittler et al.,
2017, Shchepin et al., 2019a, 2019b), knowing the
diversity of myxomycetes notably involves carrying
out species inventories, surveys and the definition of
a checklist. Some countries, especially Turkey (Sesli
et al., 2005, 2008, 2016), have started to publish lists
of myxomycetes at a regional or national level (Ndiritu
et al., 2009; Chen et al., 2010; Ranade et al., 2012).
It has been done in order to improve our knowledge
in terms of specific diversity, but also in terms of
distribution and ecological conditions related to those
taxa. Regional or ‘departmental’ (county) inventories
have already been carried out in some French
‘departments’, notably (amongst others) Rhône
(Pouchet 1926, 1930; Martin & Martin, 2002), Vosges
(Henry, 1924), Maine-et-Loire (Mornand, 1993),
Loire-Atlantique (Chassain, 1972; Le Goff & Ribollet,
2018), and even in the French island territory of New
Caledonia (Huguenin & Kohler 1969). Significant
inventories and reviews have also been carried out at
a national level (Cochet, 1977; Cochet & Bozonnet,
1980, 1984). However, many French departments do
not have published data on myxomycetes, as is the
case for Aveyron. A real need exists (i) to increase
inventories at local and national level, (ii) to carry
out a national checklist of French mycetozoa in
addition to the monography published by Pouchet
(1995) and the reference paper on myxomycetes
from France (Poulain et al., 2011), and (iii) to
publish data, unfortunately too often kept in-house,
from local naturalist association or professional and
amateur mycologists, often not consulted sufficiently.
It is within this specific framework that the work
proposed in this article is taking place. The French

department of Aveyron is home to a high biodiversity,
with numerous mycological and botanical stations.
However, to the best of our knowledge, no official
checklist on myxomycetes from Aveyron has yet been
published. Only a few scattered data in the literature
are available concerning macromycetes (e.g., Bourdot
& Galzin 1927) and lichens (e.g., Sérusiaux 1982;
Coste 2011). This article aims to contribute modestly
to the knowledge of the myxomycetes of Aveyron,
by presenting a first official preliminary list of the
species of myxomycetes present in this understudied
department.

Material & Methods

The department of Aveyron is located in the
south of France, in the Occitanie region (Fig. 1). The
climate associated is characterized and influenced by
both the Massif Central and the Mediterranean. On a
more local scale, this department can be subdivided
in three different climate regions : the West, North
and South of Aveyron, respectively having an
oceanic, mountainous and submediterranean (or
“perimediterranean”) climate.

The search for verified and published data on
myxomycetes from France, including Aveyron, was
carried out via a first preliminary work of literature
research. It was aided by technology allowing journal

<figure><img src="image_3.png" /><figcaption>**Fig. 1** - Location of the French department of Aveyron, with the main towns indicated.</figcaption></figure>
content searches, such as Google Scholar ([http://scholar.google.com](http://scholar.google.com)), JSTOR ([http://www.jstor.org](http://www.jstor.org)) and PubMed ([https://pubmed.ncbi.nlm.nih.gov/](http://pubmed.ncbi.nlm.nih.gov/)). Research for myxomycetes records in Aveyron via online-databases, including INPN ([https://inpn.mnhn.fr/collTerr/departement/choix/12](http://inpn.mnhn.fr/collTerr/departement/choix/12)), ADONIF ([https://fongibase.adonif.fr/](http://fongibase.adonif.fr/)) and iNaturalist ([https://www.inaturalist.org/](http://www.inaturalist.org/)) were also carried out. In addition to this first step, data on the species of Aveyron myxomycetes not published and collected by AMBA were added. The AMBA data come from numerous local mycological inventories throughout the Aveyron department, notably organized by its president, Jean-Louis Menos. During these inventories, by a simple method of prospecting and tracking, samples of fungi *sensu stricto* and myxomycetes were collected and identified *a posteriori* via macroscopic and microscopic criteria.

The data from these inventories were communicated internally via the edition of a booklet in 2011 (Menos & Ferrières, unpublished 2011) and updated in 2021 (Menos & Ferrières, unpublished 2021). The data from these inventories concerning Aveyron myxomycetes represent the main contribution of this article.

The taxonomic names used follow the nomenclature criteria proposed by Hernández-Crespo & Lado (2005) and only accepted taxonomic names are used. Due to the numerous changes made by molecular phylogeny in the classification of myxomycetes, and the recent redefinition of orders and families by Leontyev *et al.* (2019), the classification used in this list is that provided by MycoBank (Crous *et al.*, 2004; Robert *et al.*, 2005, 2013; consulted in July 2021), pending consensus in the phylogenetic classification of Mycetozoa. Only records identified at the species level were used for this first list. If identifications are questionable, doubtfull or merit further investigation, especially at the microscopic level, the latter are indicated with the mention To Be Confirmed (TBC) accompanied by an argument in the form of a note. TBC data was not included in the general list, but can be found in the section TBC data.

In the myxomycetes list, contributors of data apart from literature research are cited with the following abbreviation: "Liste des champignons d'Aveyron" by Jean-Louis Menos and Michel Ferrières, Mycological and Botanical Association of Aveyron, 2011: AMBA 2011 and the revised list in 2021: AMBA 2021; Jean-Louis Menos : JM; Michel Ferrières : MF; Jonathan Cazabonne : JC; Bernard Crozes : BC.

New records with the annotation 'AMBA 2011' mean the taxon concerned has been found in Aveyron over

a time period of approximately 1991 up to 2011. The annotation AMBA 2021 means the taxon was found in Aveyron between 2011 and 2021.

Each species is enumerated, and its listing is given in order of classification according to Mycobank (2021), similar to the classification used by Mifsud (2020). For each species the following information is given: species name, author(s), basionym, record sources and locality with collecting date, when available. Collecting dates were not indicated in the dataset of the AMBA. The names of the geographical localities are voluntarily retained from the original French, to keep the true meaning and precision of the indications of the authors' mother tongue.

If no previous published data of the species' presence in Aveyron existed, then new records (NR) for the department are indicated with an asterisk (*) following species name. The system of the suprageneric taxa is in accordance with Kirk *et al.* (2001) and Kirk *et al.* (2004). The authors' names are abbreviated according to Kirk & Ansell (1992). Name of the author(s), Basionym and currently accepted names were verified with MycoBank (Crous *et al.*, 2004; Robert *et al.*, 2005, 2013; consulted in July 2021), Hernández-Crespo & Lado (2005; consulted in July 2021) and the CABI Index Fungorum ([http://www.indexfungorum.org](http://www.indexfungorum.org); consulted in July 2021).

Current accepted names are given in bold in the taxonomic and synonym list. Regarding the high number of nomenclature changes, especially in the taxonomy of myxomycetes, a list of all synonyms (Appendix) for each species is appended separately following Hernández-Crespo & Lado (2005). This system is in accordance with the recommendations of the ICN, International Code of Nomenclature for algae, fungi, and plants (Melbourne Code) (Barrie *et al.*, 2012). Each entry in the synonym list (Scientific name) is given in alphabetical order, and each of the synonyms is given following the order provided by Hernández-Crespo & Lado (2005). An exception is present for *Arcyria affinis* Rostaf., 1875 which has no currently-accepted synonyms.

Synonyms based on the same type specimen are given with the symbol ≡, synonym based on other type material are given with the symbol =. “?” accompanied by a synonym name means the synonymy is doubtful or needs to be verified.

Images of some new records are given and captioned accordingly. Photos credits are indicated in each caption.
## Results

A total of 21 species, belonging to 14 genera, 7 families and 5 orders, have been listed to be present in the French department of Aveyron. Among this preliminary checklist, *Arcyria* and *Stemonitis* were the most frequent genera found (~0,14% each), followed by the genera *Lycogala*, *Physarum*, *Trichia* (~0,09% each) and *Ceratiomyxa*, *Comatricha*, *Didymium*, *Fuligo*, *Hemitrichia*, *Leocarpus*, *Mucilago*, *Reticularia* and *Tubifera* (~0,05% each).

The literature research revealed only two papers mentioning myxomycetes taxa in Aveyron (Eliasson & Lundqvist 1979; Mitchell *et al.*, 1984). Some data have been found on the ADONIF website (https://fongibase.adonif.fr/recherchecarto/), published by Jean-Claude Malaval. No records of myxomycetes from Aveyron have been noted in the INPN and iNaturalist online database. Fourteen species, *Arcyria affinis* Rostaf., *Arcyria obvelata* (Oeder.) Onsberg, *Ceratiomyxa fruticulosa* (O.F. Müll.) T. Macbr., *Fuligo septica* (L.) F.H. Wigg., *Hemitrichia clavata* (Pers.) Rostaf., *Leocarpus fragilis* (Dicks.) Rostaf., *Lycogala epidendrum* (J.C. Buxb. ex L.) Fr., *Lycogala flavofuscum* (Ehrenb.) Rostaf., *Mucilago crustacea* P. Micheli ex F.H. Wigg., *Reticularia lycoperdon* Bull., *Stemonitis axifera* (Bull.) T. Macbr., *Stemonitis splendens* Rostaf., *Trichia decipiens* (Pers.) T. Macbr., and *Tubifera ferruginosa* (Batsch) J.F. Gmel., are reported from the department for the first time. *Arcyria cinerea* (Bull.) Pers., *Comatricha laxa* Rostaf., *Didymium difforme* (Pers.) Gray, *Physarum album* (Bull.) Chevall., *Physarum decipiens* M.A. Curtis, *Stemonitis fusca* Roth and *Trichia varia* (Pers. ex J.F. Gmel.) Pers., have already been published in the literature or online databases. Of note, a specimen of *Fuligo candida* has been observed and identified by Michel Ferrières, based on macroscopic characteristics, in Aveyron. As no microscopic analysis was performed, the authors decided not to include this taxon in this present preliminary study, in order to avoid potential errors or doubtful data. In addition, two identifications were found to be questionable or would have required further microscopic studies, namely *Badhamia capsulifera* (Bull.) Berk. and *Arcyria ferruginea* Saut., respectively mentioned by MF and AMBA 2011. They have been included in the category "TBC data" and not included in the general list of Aveyron myxomycetes, in order to avoid integrating errors or invalidated data. The new data on Aveyron myxomycetes are those collected by AMBA (Jean-Louis Menos, Michel Ferrières, Bernard Crosses and Jonathan Cazabonne) and not published

until now. These data are therefore considered as new records for the department.

Another specimen of *Leocarpus fragilis* have been found in Aveyron by MF. However, the identification might be doubtful and would have deserved further microscopic study. These are either young subjects of *Leocarpus fragilis* which do not yet show the foot and the elongation/stretching characteristic of the mature fructification or a species of the genus *Trichia*, a hypothesis which is not excluded.

TBC Data

*Badhamia sp.* *

Fig. 13

**Reference:** MF, 09/03/2013

**Note:** The specimen collected by MF belongs to the genus *Badhamia*. However, without the material retained to carry out a microscopic study, identification stops at the level of the genus. However, several hypotheses can be made. A microscopic study could have confirmed that it was *Badhamia capsulifera* (Bull.) Berk., 1852. In addition, the little calcareous peridium evokes *B. foliicola* Lister, 1897, if the support was on the ground, or *B. utricularis* (Bull.) Berk., 1852 whose hypothallus is not developed. Consequently, this specimen is attributed a « To Be Confirmed » mention.

**Basionym:** *Arcyria ferruginea* Saut., 1841

**Reference:** JM, locality unknown.

**Note:** It is very likely that the species harvested is *Arcyria ferruginea*, especially because of its capillitum weakly attached to the cup. However, since the specimen has not been conserved by the determiner, confirmation on microscopic characters cannot be conducted. As a result, this species was not included in the general List, and was given a “To Be Confirmed (TBC)” endorsement.

## Discussion and Conclusion

It should be noted that the material related to the specimens and records mentioned in the literature and by Jean-Claude Malaval were not examined by the authors. This research and data collection

work on Aveyron myxomycetes is intended to be as exhaustive as possible. However, unpublished data in both the literature and online databases may exist and therefore not be mentioned in this preliminary list. This list is therefore destined to be completed in the coming years. If new data is accumulated in the future, additions to this first list will be made and published.

Most of the species recorded in this bibliographic and inventory work are common and present in other French departments. This relatively small number of species of myxomycetes in Aveyron reflects a significant bias, notably the lack of inventory and studies on myxomycetes. It can reasonably be assumed that this list represents only a very small subsection of the myxomycete diversity present in the department. This list is obviously destined to be completed and complemented by other data in the coming years. This work was a way to value the contribution and investment of local mycological associations, data held by amateur mycologists and to encourage mycologists from Aveyron or more widely France to come and contribute to the knowledge of myxomycetes from Aveyron and other French departments.

**Acknowledgments:** The authors would like to thank all the members of the AMBA who have contributed over the decades to the collection of Myxomycetes and Fungi in general, and this for decades. Special thanks go to Michel Ferrières for having communicated some localities for *Leocarpus fragilis* and *Mucilago crustacea* in Aveyron. Thanks also to Gérard Leduc for the magnificent photos taken during the inventories carried out independently or with the AMBA. The authors also thank Bernard Crozes for providing his data on myxomycetes from Aveyron to the AMBA. Our warm greetings go to Xavier Bossier for having read and commented on the earlier version of this manuscript, as well for the reviewer Marianne Meyer for her constructive suggestions.

**Contributions:** Jonathan Cazabonne initiated, conceptualized and wrote the manuscript. Jean-Louis Menos and Michel Ferrières provided most of the data on Aveyron's myxomycetes. JC, MF and JM all contributed to the bibliographic research. All three authors have read and accepted the final version of the published manuscript.
