Gerronema confusum (Porotheleaceae), a new species from North China

Gerronema confusum sp. nov. is described and illustrated from North China, which is diagnosed by the combination of grayish brown omphalinoid basidiomata, decurrent lamellae, a central stipe, smooth, ellipsoid to subglobose, inamyloid basidiospores, 1–2-spored basidia, abundant cheilocystidia, a pileipellis disrupted by clusters of pileocystidia, and a stipitipellis disrupted by caulocystidia. ITS-phylogeny supported G. confusum as a distinct species.
