Species of Radulomyces (Radulomycetaceae, Agaricales) with spines were studied by morphological and molecular methods. Phylogenetic analyses and morphological studies show that Radulomyces paumanokensis is a later synonym of Radulomyces copelandii and that Radulomyces licentii is a distinct taxon. Based on morphologic and molecular data, the new genus Noblesia (Meruliaceae, Polyporales) is proposed to accommodate Sistotrema croceum and Peniophora femsjoeensis. Sarcodontia is emended and restricted to three species with 13 taxa excluded from the genus. For many years, Sarcodontia crocea was based on an erroneous concept of Sistotrema croceum. The correct name for the taxon with striking yellow spines found on Malus and Pyrus in Europe is Sarcodontia setosa; its North American sister species is Sarcodontia amplissima comb. nov. Hydnum sulphureum is a synonym of Sarcodontia uda, and Acia flava is a later synonym of Xylodon quercinus. Species excluded from Sarcodontia are discussed, and the new combination Hyalodon sibirica is proposed.
