On the basis of morphology, the non-gelatinous species of
During field trips in Australia, three specimens bearing corticioid basidiomes and longitudinally septate basidia were collected. Based on these specimens, a new species of
The studied specimens are preserved at the
Crude DNA was extracted from basidiomes of dry specimens using FH Plant DNA Kit (Beijing Demeter Biotech Co., Ltd., Beijing, China), and then directly used as template for subsequent PCR amplifications. The primer pairs ITS5/ITS4 (
