Abstract

Using chicken feathers as bait, Acremoniumglobosisporum sp. nov. and Acremoniumcurvum sp. nov. were collected from the soil of Yuncheng East Garden Wildlife Zoo and Zhengzhou Zoo in China. They were identified by combining the morphological characteristics and the two-locus DNA sequence (LSU and ITS) analyses. In the phylogenetic tree, both new species clustered into separate subclades, respectively. They were different from their allied species in their morphology. The description, illustrations, and phylogenetic tree of the two new species were provided.

Keywords: Acremonium; filamentous fungi; phylogeny; taxonomy.
