About the lab is a French non-profit organization devoted to the scientific study of fungi belonging to Ascomycetes, especially the taxonomy.

Featured projects (1)

To have a better knowledge of the Ascomycota, especially the discomycetes, growing in the Alpine Zone, through the organization of forays in the Alps and Pyrenees, and publications (reports, taxonomic novelties...) More information here:

Featured research (4)

This report gives the results of the mycological survey carried out in June 2021 in Auvergne (France), in the south of Cantal, and mainly centred on ascomycetes. The list of species observed and studied in each site is provided. Notes and illustrations are proposed for some of the most interesting species: Capronia pleiospora, Dendrostoma atlanticum, Hymenoscyphus varicosporoides, Lachnum impudicum, L. salicariae, Nectria berberidicola, Psilachnum acutum, Strossmayeria basitricha, Unguiculariopsis castanea and Urceolella aspera.
Two new species of Stylonectria are described and illustrated from specimens collected in the French Alps. Ascomatal morphology, fungicolous lifestyle, and phylogenetic comparison of their ITs sequences with species in six similar genera of Nectriaceae having a fusarium-like asexual morph support their placement in Stylonectria. Based on morphological divergences of both sexual and asexual morphs, as well as the ITs sequences from known Stylonectria species, S. alpina and S. tuedensis are proposed as new species. Résumé : deux nouvelles espèces de Stylonectria sont décrites et illustrées à partir de matériel récolté dans les Alpes françaises. La morphologie des ascomes, l'habitat fongicole et la comparaison phylogénétique de leurs séquences ITs avec celles d'espèces appartenant à six genres semblables de Nectriaceae ayant un stade asexué de type fusarium soutiennent leur placement dans les Stylonectria. En se fondant sur les divergences morphologiques de leurs formes sexuées et asexuées, ainsi que de leurs séquences ITs par rapport à celles des espèces connues de Stylonectria, S. alpina et S. tuedensis sont proposées comme nouvelles espèces.
This report gives the results of the mycological survey done in June 2019 around Montgreleix, in Auvergne (France), mainly centred on spring ascomycetes. The list of species observed and studied in each site is provided. Notes and illustrations are proposed for some of the most interesting species: Hymenoscyphus salmanovicensis, H. scutuloides, Lachnum juncinum, L. pubescens, Mellitiosporiella “sedicina”, Myriosclerotinia curreyana and Phomatospora minutissima
Species of Tarzetta are morphologically well-defined but their taxonomy is confused because of the multiple interpretations of the oldest names, i.e. T. catinus and T. cupularis. The exploration of this genus with molecular and ecological data gave us the opportunity to partially clarify its taxonomy and to propose typifications of names. The type collections of T. pusilla, T. gaillardiana, and T. spurcata in the sense of Harmaja were reviewed. Hypotarzetta insignis, a semi-hypogeous species, is reinstated in Tarzetta based on molecular data. New species are also described and illustrated: T. gregaria sp. nov. is characterized by its small size and gregarious orangish ascocarps, T. alnicola sp. nov. is a small species associated with alders in riparian woodlands, T. alpina sp. nov. grows in boreo-alpine regions, T. sepultarioides sp. nov. is characterized by its Sepultaria-like appearance and ascus base shape, T. melitensis sp. nov. is a small species described from Malta, and T. quercus-ilicis sp. nov. is a small, sessile species, associated with Quercus ilex in Mediterranean regions. T. betulicola is a provisional name proposed for a species from the T. catinus complex, probably associated with birch trees
