Species of Mycenasect.Calodontes are representative the Mycena genus as a whole and easily recognised by pinkish, reddish, purplish to brownish pileus larger basidiomata. Furthermore, colour in species sect. Calodontes often has transition or changes different stages combination with cystidia basidiospores can be used recognise taxa within this section. To date, 19 have been reported worldwide. Including our recent description M.yuezhuoi, five recorded China. During examination specimens collected coniferous forests mixed broadleaf-conifer temperate regions China, additional assigned were identified. Four new recognised, based mostly on characters cystidia. Phylogenetic analysis sequence data from multiple DNA (ITS + rpb1 tef1) supported morphological evidence. Here, we propose M.polycystidiata, M.rufobrunnea, M.shengshanensis M.subulata Mycenasect.Calodontes. Morphological descriptions, line drawings, habitat photos comparisons closely-related provided. A key 23 known is presented.
