Yuchengia

Yuchengia is a fungal genus in the family Polyporaceae. It is a monotypic genus, containing the single species Yuchengia narymica, a crust fungus formerly placed in the genus Perenniporia and originally described as Trametes narymica by Czech mycologist Albert Pilát.

Description

Yuchengia narymica has a cream to yellowish buff pore surface with angular pores. The hyphal system is dimitic, and the generative hyphae have clamp connections. Similar to Perenniporia, Yuchengia has thick-walled and cyanophilous spores. Yuchengia is distinguished from Perenniporia in its acyanophilous and amyloid skeletal hyphae that dissolve in KOH, and non-dextrinoid spores.
