Two new species of Coltricia, C. subcinnamomea and C. 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-1α confirmed the generic placement of the two new species. Coltricia subcinnamomea is 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 × 6.2–6.8 μm. Coltricia subverrucata is 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 × 6.0–7.0 μm.
