Bian LS, Dai YC. Morphological and molecular evidence for three new species of Coltricia (Hymenochaetaceae, Basidiomycota) from southern China. Mycologia. 2017;109(1):64-74.
Three new species of Coltricia from southern China are described on the basis of morphological characters and molecular analyses. Phylogenetic analyses based on nuc rDNA ITS1-5. 8S-ITS2 and partial 28S rDNA, and partial sequences of genes for RNA polymerase II subunits 1 and 2 confirmed the generic placement of the three new species. Coltricia lateralis is characterized by small, laterally stipitate basidiocarps, obtuse pileus margin, cinnamon-buff to honey yellow pore surface, and broadly ellipsoid basidiospores that measure 7-8 × 5-6 µm. Coltricia rigida is characterized by large, woody-hard fan-shaped basidiocarps, small pores (7-8 per mm), presence of septate sclerified hyphae, and subglobose to globose basidiospores that measure 6-7 × 5-6. 5 µm. Coltricia wenshanensis is characterized by centrally stipitate basidiocarps, a distinctly concentrically zonate and sulcate pileal surface, large pores (0. 5-2 per mm), and broadly ellipsoid to subglobose basidiospores that measure 7. 5-8 × 6-7 µm.
