Abstract

A taxonomic revision of Conidiobolus s.l. (Ancylistaceae, Entomophthorales) delimited all members that form capilliconidia into the genus Capillidium. In this study, we report two new species of Capillidium that were isolated in China. Capillidiummacrocapilliconidium sp. nov. is characterised by large capilliconidia. Capillidiumjiangsuense sp. nov. is differentiated by large capilliconidia and long, slender secondary conidiophores. Phylogenetic analyses were performed using sequences from the nuclear large subunit of rDNA (nucLSU), the mitochondrial small subunit of rDNA (mtSSU) and elongation-factor-like (EFL). The analyses revealed sister relationships between Ca.macrocapilliconidium sp. nov. and Ca.globuliferus / Ca.pumilum and between Ca.jiangsuense sp. nov. and Ca.denaeosporum. Additionally, a new combination of Ca.rugosum (Drechsler) B. Huang & Y. Nie comb. nov. is proposed herein. An identification key is provided for the ten accepted Capillidium species.
