Hydnellum dianthifolium sp. nov. (Basidiomycota, Thelephorales), a new tooth-fungus from southern Europe with notes on H. concrescens and H. scrobiculatum

Abstract

The new species Hydnellum dianthifolium is described and illustrated from Pinus brutia forests in Cyprus and southern Italy. Evidence from ITS-based phylogenetic and morphological analyses, including scanning electron microscopy is provided, and the relevant literature is reviewed. The long-standing taxonomic problems associated with the closely affiliated taxa Hydnellum concrescens and H. scrobiculatum, both variously interpreted in the literature and as yet phylogenetically unresolved, are discussed.
