Leptodophora gen. nov. (Helotiales, Leotiomycetes) proposed to accommodate selected root-associated members of the genus Cadophora.

Abstract

Cadophora orchidicola , a root-associated asexual species, did not have a clear placement within the paraphyletic genus Cadophora because it was not represented by sequences derived from the type material . Based on four newly obtained molecular marker sequences from the ex-type strain, a new genus, Leptodophora , is proposed, typified with C. orchidicola , as well as new combinations for three recently described and closely related species. In addition, a new species, Collembolispora disimilis , is proposed for a fungus producing phialidic conidiogenous cells and previously treated as Cadophora sp.
