Abstract

A new species of Phaeoacremonium magnosporus sp. nov. was isolated in culture from the air in Sichuan Province, China, and described. Phylogenetic tree derived from neighbor-joining analysis based on a multi-locus concatenated dataset of the internal transcribed spacers (ITS), actin (ACT) and β-tubulin (TUB2) genes revealed that the novel species clustered within the Phaeoacremonium clade with a distinct lineage. Two strains of Phaeoacremonium magnosporus were related to P. paululum and P. alvesii. Unlike P. paululum CBS 142705, the new species exhibited growth well at 30 °C; and the new species differed from P. alvesii CBS 110034 in that it could not produce yellow pigment. The most distinctive characteristic of the novel species is its lack of a host association, which distinguishes it from all previously described Phaeoacremonium species. Herein, we propose a new species, P. magnosporus sp. nov.
