Abstract

A new species of Koorchaloma is described based on morphology and multigene phylogenetic analyses of ITS, LSU and RPB2. Phylogenetic analyses showed our strain clusters with K. europaea with moderate statistical support. Koorchaloma oryzae sp. nov. is morphologically similar to K. europaea, but it can be distinguished by the conidiophores and conidia, while ITS pairwise nucleotide comparison of these two species also revealed differences. Koorchaloma oryzae is compared with all known Koorchaloma species, and a key to Koorchaloma species is provided. Genealogical concordance phylogenetic species recognition analysis (PHI test) results of the new species and closely related species are also given.
