Twenty-two of them are described here as new species. Epitypes are proposed for <i>H. repandum</i> and <i>H. rufescens</i>. The majority of the species are currently known only from a single continent. The barcodes produced in this study are deposited in the RefSeq database and used as a basis to name species hypotheses in UNITE. Eleven infrageneric clades recovered in a phylogenetic analysis are supported by morphological characteristics and formally recognized: subgenera <i>Alba, Hydnum, Pallida</i>, and <i>Rufescentia</i>; sections <i>Hydnum, Olympica, Magnorufescentia</i>, and <i>Rufescentia</i>; and subsections <i>Mulsicoloria, Rufescentia</i>, and <i>Tenuiformia</i>.</p> 2018-09-14 15:39:29 Cantharellales commercial mushrooms cryptic species ectomycorrhizae fungal diversity ITS type specimens 29 new taxa 2 new typifications
