Hyalinostachys C.G. Lin & K.D. Hyde, gen. nov.
MycoBank number: MB 555606; Index Fungorum number: IF 555606; Facesoffungi number: FoF 03883; 1 species with sequence data.
Etymology: Name reflects the hyaline stachybotrys-like conidiophores and conidia.
Saprobic on plant host. Sexual morph: Undetermined. Asexual morph: Hyphomycetous. Colonies effuse, hairy, pale to pale brown. Mycelium partly superficial and partly immersed. Conidiophores macronematous, mononematous, single or in small groups, simple or branched, erect, straight, septate, thick-walled, smooth, hyaline, narrower at the apex. Conidiogenous cells monophialidic, discrete, determinate, terminal, elongate ampulliform, clavate or subcylindrical, the outer ones somewhat curved and ventricose, hyaline, smooth; conidial mass slimy, pale orange. Conidia acrogenous, aseptate, smooth, hyaline, cylindrical, ellipsoidal.
Type species – Hyalinostachys cylindrospora C.G. Lin & K.D. Hyde
Notes – The combined LSU and rpb2 phylogenetic analyses indicate that Hyalinostachys forms a separate clade and sister taxon to Achroiostachys, Globobotrys, Melanopsamma and Sirastachys in Stachybotryaceae (Fig. 15). Hyalinostachys is distinguished from these genera by simple or branched, thick-walled, smooth and hyaline conidiophores and hyaline, cylindrical or ellipsoidal conidia.
