This is the third paper in the series, Mycosphere notes, wherein we provide notes on various fungal taxa. In this set of notes, we deal with species found on the grape genus, Vitis, one of the most important economically important crops, grown worldwide. We provide notes on 67 taxa, including two new species, Alternaria italica and Alfaria vitis, an asexual morph for Alfaria cyperiesculenti and 41 new host records or distribution records. The taxonomic placement of most taxa discussed in this study is based on a modern taxonomic framework based on analysis of multi-gene sequence data.

Twenty seven species of Psathyrella have been found in Northeast China. Amongst them, P. conica, P. jilinensis, P. mycenoides and P. subsingeri are described as new species, based on studying morphological characteristics and phylogenetic analyses. Detailed morphological descriptions, line drawings and photographs of the new species are presented. Phylogenetic analysis of the nuclear ribosomal internal transcribed spacer (ITS) region and an identification key to the 27 Psathyrella species occuring in Northeast China are provided.

Three new species of Russulasection Ingratae, found in Guizhou and Jiangsu Provinces, southern China, are proposed: R. straminella, R. subpectinatoides and R. succinea. Photographs, line drawings and detailed morphological descriptions for these species are provided with comparisons against closely-related taxa. Phylogenetic analysis of the internal transcribed spacer (ITS) region supported the recognition of these specimens as new species. Additionally, R. indocatillus is reported for the first time from China and morphological and phylogenetic data are provided for the Chinese specimens.

Typhrasa is a rare genus that comprises two species and that has previously been reported only from Europe and North America. The present study expands the geographical scope of the genus by describing two new species – T. polycystis and T. rugocephala – from subtropical China. The new species are supported by morphological characteristics and phylogenetic analyses (ITS, LSU and tef-1α). The new species have very similar morphological characteristics and are 98% similar in their ITS region. However, T. rugocephala has two types of long gills at the same time, rarely fusiform pleurocystidia with rostrum. Detailed descriptions, colour photos, illustrations and a key to related species are presented in this paper.
