Additions to Lyophyllaceae s.l. from China.

Four new species, viz. , , and , are described in northern China. Comparisons are made of macro- and micromorphological features among the new species and closely related species within the genus. The new species feature unique morphological characteristics that separate them from the previously described species. is characterized by medium- to large-sized basidiocarps, greyish cream, felty pileus and non-cellular epicutis. The key characteristics of are rose-brown to greyish-brown pileus, stone-brown stipe and non-cellular epicutis. The unique morphological characteristics of . that distinguish it from its closely related species are pastel red to dull-red pileus and stipe surface with densely white pruina. The main characteristics of are deeply depressed dark orange to light-brown pileus, central stipe and subglobose-ellipsoid spores. Phylogenetic analyses based on the ITS and 28S regions indicated that the four new species are distinct and monophyletic. Full descriptions, color images, illustrations and a phylogenetic tree that show the placement of the four new species are provided. A key to the species reported from China is also given.
