Dematiohelicomyces
Dematiohelicomyces Y.Z. Lu, Boonmee & K.D. Hyde, in Lu et al., Fungal Diversity 92: 159 (2018).
Index Fungorum number: IF 554824; Facesoffungi number: FoF 04701, 1 morphological species (Species Fungorum 2022), 1 species with molecular data.
Saprobic on decaying wood. Sexual morph: Unknown. Asexual morph: Hyphomycetous, helicosporous. Colonies on the substratum superficial, effuse, gregarious, white to light pink. Mycelium mostly immersed, partly superficial, composed of branched, septate hyphae, pale brown, with masses of crowded, glistening conidia. Conidiophores macronematous, mononematous, cylindrical, mostly unbranched, 0–3-septate, pale brown, smooth-walled. Conidiogenous cells holoblastic, mono- to polyblastic, integrated, sympodial, terminal, cylindrical, truncate at apex after conidial secession, pale brown, smooth-walled. Conidia solitary, acrogenous, helicoid, dry, coiled 1–3 times, becoming loosely coiled or uncoiled in water, rounded at tip, multi-septate, guttulate, hyaline, smooth-walled (adapted from Lu et al. 2018).
Type species: Dematiohelicomyces helicosporus (Boonmee, Y.Z. Lu & K.D. Hyde) Y.Z. Lu
Notes: Dematiohelicomyces resembles Helicomyces in having short conidiophores that are 0–3-septate, and helicoid conidia, having a spathulate basal end cell but differs from it in having brown conidiophores. Dematiohelicomyces is morphologically and phylogenetically a distinct and well-defined genus in Tubeufiaceae. Molecular markers available for Dematiohelicomyces are ITS, LSU, RPB2 and TEF-1.
