Abstract

Araneogenous fungi, a specialized group of fungi pathogenic to spiders, play an irreplaceable role in regulating spider population dynamics and maintaining ecological balance. During a survey of araneogenous fungi in southwestern China, a new species, Arachnidicola guiyangensis was isolated and introduced. Morphological characteristics, phylogenetic analyses and Genealogical Concordance Phylogenetic Species Recognition (GCPSR) analysis supported the establish of the new species. It different from other related species by its shorter conidiophores, shorter phialides and larger ellipsoidal to subglobose conidia.
