摘要：Three new species of Coltricia, C. fimbriata, C. lenis, and C. tenuihypha, are described from China based on both morphological and molecular data. Phylogenetic analyses based on rDNA ITS1-5.8S-ITS2 (ITS), 28S rDNA (LSU), 18S rDNA (SSU), mitochondrial 12S rDNA (mtSSU), RNA polymerase II subunits 1 (RPB1), and EF-1 alpha (TEF1) confirmed the generic placement of the three new species. Coltricia fimbriata is characterized by centrally stipitate basidiocarps, thin and curled pileal margin with tufts of hairs, 1-3 pores per mm, and ellipsoid to broadly ellipsoid basidiospores (6.3-8.0 x 4.3-5.3 mu m). Coltricia lenis is characterized by centrally stipitate basidiocarps, distinctly concentrically zonate and sulcate pileal surface, soft to spongy stipes when dry, 0.5-2 pores per mm, oblong-ellipsoid to ellipsoid basidiospores (7.0-9.3 x 4.5-5.8 mu m). Coltricia tenuihypha is characterized by eccentrically to centrally basidiocarps, fan-shaped to circular pilei, 1-3 pores per mm, narrow and skeletal-alike hyphae present in the stipe, ellipsoid to broadly ellipsoid basidiospores (7.3-9.3 x 5.5-6.8 mu m). An identification key to the species of Coltricia recorded in China is also provided.
