Biotrophic and saprophytic fungi from the - clade (Entolomataceae): two new species and one new record in subtropical China.

This study proposes two new species and a new record in the clade, based on comprehensive morphological and molecular analyses. The nuc rDNA internal transcribed spacer region ITS1-5.8S-ITS2 (ITS), the large subunit ribosomal RNA gene (LSU), the RNA polymerase II second largest subunit () and the translation elongation factor 1-alpha gene (), were employed to elucidate the relationships of and . The first species, , is capable of infecting the leaves of host plants in the genera and , exhibiting typical biotrophic behaviour while also demonstrating saprophytic growth on soil. Intraspecific comparisons were conducted, examining environmental factors as well as macro- and microscopic characteristics amongst individuals found on different plant hosts. Furthermore, this study reports the new saprophytic species, and provides a detailed description of , a newly-recorded species in China.
