Morphology and Phylogeny Reveal Three Montagnula Species from China and Thailand.

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 .
