Abstract

Four stains were isolated from two fresh twigs of Helwingia himalaica and two dead woods during investigations of micro-fungi in China and Thailand. Phylogenetic analyses of four gene regions LSU, ITS, SSU and tef1-α revealed the placement of these species in Montagnula. Based on the morphological examination and molecular data, two new species, M. aquatica and M. guiyangensis, and a known species M. donacina are described. Descriptions and illustrations of the new collections and a key to the Montagnula species are provided. Montagnula chromolaenicola, M. puerensis, M. saikhuensis, and M. thailandica are discussed and synonymized under M. donacina.

Keywords: Pleosporales; multi-gene phylogeny; sexual morph; taxonomy; two new species.
