Hypocreomycetidae, Microascales, Chadefaudiellaceae, Chadefaudiella

Index Fungorum number: IF 928; Facesoffungi number: FoF 02103; 2 morphological species (Species Fungorum 2020).


Saprobic on mammalian manure. Sexual morph: Ascomata light yellow, relatively large (500–1500 μm high, 150–250 μm wide), elongate or hemisphaerical, immersed at the base, pale yellow to brown, basal perithecial envelope black, round, carbonaceous, foot cylindrical, light yellow to brown, translucent, striated, upper part with brown, anastomosing setae or setae lacking, carbonaceous, lacking ostioles. Peridium composed of pseudoparenchymatous cells forming a textura angularis inserted in the substrate and an aerial “capillitium”. Asci 8-spored, globose, evanescent. Ascospores 1-celled, fusiform, thick, striate, not turning into reddish-brown upon application of Melzer’s reagent (non-dextrinoid). Asexual morph: Undetermined (adapted from Maharachchikumbura et al. 2016).


Type species: Chadefaudiella quezelii Faurel & Schotter, C. r. hebd. Séanc. Acad. Sci., Paris 249(no. 1): 152 (1959)


Notes: Chadefaudiella is placed in the Chadefaudiellaceae, Microascales because it produces asci in chains and has other characteristics of Microascaceae taxa. The ascospore wall of C. quezelii is striate and non-dextrinoid (Locquin-Linard 1973, 1975). Usually Chadefaudiella species are saprobic on mammalian dung and were found on Gazelle dung from Koudou, Chad (Africa) (Benny & Kimbrough 1980).
