Grammothelopsis

Grammothelopsis Jülich 1982, in Cui, et al., Fungal Diversity 97, 137–392 (2019)

Diagnosis: Basidiocarps annual, resupinate to effused-reflexed, adnate. Pore surface light color; pores shallow, irregular. Subiculum thin. Hyphal system dimitic; generative hyphae bearing clamp connections; skeletal hyphae strongly dextrinoid, CB+. Dendrohyphidia usually present in the hymenium, hyphal pegs present. Basidiospores ellipsoid, hyaline, thick-walled, smooth, weakly dextrinoid, weakly CB+

Index Fungorum Number:  IF17693

Type species: Grammothelopsis macrospora (Ryvarden) Jülich 1982

Notes: Grammothelopsis was established by Jülich (1981) and typified by G. macrospora (Ryvarden) Jülich. It is characterized by resupinate to effused basidiocarps, shallow irregular pores, and large thick-walled variably dextrinoid basidiospores. Grammothelopsis species occur mostly in tropical Africa and America (Ryvarden & de Meijer 2002; Robledo & Ryvarden 2007), but two species recently described from tropical China (Dai et al. 2011; Zhao & Cui 2012).
