Seven new species in Piloderma (Atheliales, Basidiomycota) from the Northern Hemisphere recovered through morphological and molecular methods

The ectomycorrhizal genus Piloderma (Atheliales, Basidiomycota) is studied using morphological and molecular methods. Seven new species are identified and described, viz. P. cinicola, P. craurum, P. egens, P. exiguum, P. humile, P. ochraceum, and P. rallum, bringing the total number of accepted species to 13. All new species are supported by ITS sequences from basidiomata and from environmental soil and root-tip sequences available in public databases. A key to all species in Piloderma is provided.
