摘要：Two new species ofColtricia,C. subcinnamomeaandC. subverrucata, are described from China based on both morphological and molecular data. Phylogenetic analyses based on nuc rDNA ITS1-5.8S-ITS2, partial 28S rDNA and partial 18S rDNA, mt partial 12S rDNA, partial sequences of genes for RNA polymerase II subunits 1 and 2, and partial sequences of genes for EF-1 alpha confirmed the generic placement of the two new species.Coltricia subcinnamomeais characterized by stipitate, mesopodal basidiocarps, a slightly shiny pileal surface, 2-3 pores per mm, and broadly ellipsoid to subglobose basidiospores, 8.0-9.5 x 6.2-6.8 mu m.Coltricia subverrucatais characterized by stipitate, mesopodal basidiocarps, a faintly concentrically zonate pileal surface with radiating lines, 0.5-2 pores per mm, strongly verrucose hyphae and broadly ellipsoid basidiospores, 7.8-9.0 x 6.0-7.0 mu m.
