Revisiting the genus Hyphodermella (Basidiomycota, Polyporales) with descriptions of three new species
In this study, we revisited Hyphodermella with the aim of circumscribing the genus, exploring its species diversity, re-evaluating the usefulness of the morphological characters used for its identification, and providing a more precise interpretation of its geographical distribution. Specimens were studied using morphological characters and molecular phylogenetic analyses of the ITS, LSU, RPB1, and RPB2 regions. The results of the concatenated phylogenetic trees based on two and four markers support the monophyly of Hyphodermella and the original description of the genus. Morphological and molecular evidence delimit six clades and one singleton within the Hyphodermella core; three of these correspond to species already described, Hyphodermella corrugata, H. maunakeaensis, and H. rosae, and three correspond to new species, Hyphodermella paulusiae sp. nov., H. ryvardenii sp. nov., and H. salcedoae sp. nov., which are described in this paper.
