Morphological and molecular evidence support a new endophytic fungus, Chaetomella endophytica from Japan

Abstract

© 2018 The Mycological Society of Japan A new endophytic fungus, described herein as Chaetomella endophytica sp. nov., was isolated from stems of Rosa arvensis in Yamaguchi Prefecture, Japan. Morphological investigations revealed that its conidia are shorter and narrower than other known Chaetomella species. Phylogenetic analysis of three combined loci (large subunit, internal transcribed spacer, and small subunit regions of ribosomal DNA) confirmed that it is a new species within the family Chaetomellaceae. A full description, illustrations and a phylogenetic tree showing the position of C. endophytica are provided.
