Unveiling the diversity of the families Cyphellaceae and Mycenaceae from Southeast Asia

Nine new species of the families Cyphellaceae and Mycenaceae are described from Asia, China, and Pakistan on the basis of detailed morphological and molecular investigations. Seven species belong to the genus Mycena ( M. albomarginata , M. oblongispora , M. lavendula , M. longnanensis , M. minispora , M. pakistanica , and M. tephroleuca ), and one species each belongs to Atheniella and Phloeomana . These Mycena species belong to three sections. Five Mycena species, i.e., M. lavendula , M. longnanensis , M. minispora , M. pakistanica , and M. tephroleuca , have been assigned to Mycena sect. Calodontes , while one species ( M. albomarginata ) belongs to Mycena sect. Mycena and one ( M. oblongispora ) to Mycena sect. Fragilipedes . All of the new species are supported by phylogenetic analyses based on the nuclear internal transcribed spacer (ITS) of nuclear ribosomal DNA and translation elongation factor 1-alpha ( tef1-α ).
