Alanomyces Roh. Sharma, Phytotaxa 297(2): 170 (2017).

Index Fungorum number: IF 804153; Facesoffungi number: FoF 07623, 1 morphological species (Species Fungorum 2022), 1 species with molecular data.

Colony fast growing, initially greenish-black, later fuscous black- violaceous black. Sexual morph: Unknown. Asexual morph: Pycnidia fuscous black, immersed to semi immersed, setose at base, multilocular. Peridium textura angularis dark brown outer layers of pycnidia. Conidiogenous cells hyaline. Chlamydospores dark brown (adapted from Sharma et al. 2017).


Type species: Alanomyces indica Roh. Sharma  


Notes: Alanomyces is characterised by greenish-black, to fuscous black colony on PDA, fuscous black pycnidia, hyaline conidiogenous cells and dark brown chlamydospores. Sharma et al. (2017) placed Alanomyces in Aplosporellaceae based on multigene analyses of ITS, LSU, TEF-1 and BTUB sequence data. Alanomyces differs from Aplosporella in that the latter has multilocular pycnidia with common ostiole, brown aseptate, verrucose spermatia and fusiform paraphysis (Sharma et al. 2017). Alanomyces is also characterised by multilocular pycnidia with peridium comprising textura angularis but have different ostiole and develops numerous thick-walled chlamydospores in chains (Sharma et al. 2017). Alanomyces is morphologically and phylogenetically a well-defined genus in Aplosporellaceae. Molecular markers available for Alanomyces are ITS, LSU, BTUB and TEF-1.
