摘要

Russulales comprises a highly diverse group of species with respect to basidiocarp morphology and hymenophore type. We reconstructed evolutionary histories of Russulales using ITS and nLSU rDNA sequence data with an emphasis on phylogeny of wood-inhabiting hydnoid species in this order. Based on the combination of morphological and molecular evidence, two new genera, three new species and two new combinations are proposed. Dentipellis microspora and D. coniferarum, newly described, were placed outside Hericiaceae but are provisionally treated in Dentipellis due to their morphological similarity to the generic type. Dentipellis leptodon and D. taiwaniana are transferred to the new genus Dentipellicula as D. leptodon and D. taiwaniana, which is designated as the generic type. The new genus Dentipellopsis was erected to accommodate a newly described species D. dacrydicola. Characters are provided in a generic key to distinguish Dentipellicula, Dentipellis and Dentipellopsis that morphologically are highly similar in addition to a key to the current species in Dentipellis. A new species of Gloeodontia was described based on both molecular and morphological data, and a key to this genus also is provided.
