Abstract

A slow growing, asexual fungus that produces numerous arthroconidia was isolated during a mycobiota survey of pig farm soil in China. Phenotypic characteristics and phylogenetic analysis based on ITS and LSU rDNA sequences showed that it is a new species in the genus Arachnomyces, and the name Arachnomyces jinanicus was introduced. A. pilosus and A. scleroticus are new combinations for Chrysosporium pilosum and Onychocola sclerotica (=Malbranchia scleroticus) respectively. Currently, 11 species are accepted in Arachnomyces and an overview with type information and reference sequence data is given. The phylogenetic relationships of species within the genus are discussed, and a dichotomous key for distinguishing all reported Arachnomyces species is provided.
