Morpho-phylogenetic analyses of two novel edible mushrooms from China and a mini review of (Agaricales, Lyophyllaceae) cultivation and bioactivities.

plays an important role in the natural ecosystem and has significant economic value. Some species of this genus have been cultivated in Asia, America, and Europe. This study describes four edible species of , two of which were newly discovered. has a dark grayish orange pileus, a grayish orange upper part of the stipe, and globose, subglobose to broadly ellipsoid basidiospores, while has a dark gray-orange when injured pileus, dark grayish orange points and lines on the stipe surface, and quadrangular to broadly fusiform basidiospores. Molecular phylogenetic analyses using the internal transcribed spacer ITS1-5.8S-ITS2 ribosomal RNA (ITS), the large subunit ribosomal RNA (LSU), the second-largest subunit of RNA polymerase II (), and translation elongation factor 1-alpha () indicated that is related to , , and , and has an affinity to and . We also summarize the cultivation techniques of the two edible species, and .
