Type specimens of fifteen, resupinate, crustose basidiomycetes with aculei described by various authors were examined. Nine taxa are later synonyms: Hydnum albiceps Berk. & Rav. (= Phlebia fascicularis), Hydnum chrysodon Berk. & M.A. Curtis (= Hydnophlebia chrysorhiza), Hydnum hypochrum Berk. & Broome (= Dentipellis leptodon), Hydnum micheneri Berk. (= Steccherinum ciliolatum), Hydnum pallidum Cooke & Ellis (= Xylodon fimbriiformis), Hydnum schweinitzii Berk. & M.A. Curtis (= H. chrysorhiza), Irpex furfuraceovelutinus Rick (= Kneiffiella stereicola), Irpex galzinii Bres. (= Amyloporia sinuosa), and Merulius elliottii Massee (= H. chrysorhiza). Irpex fimbriiformis Berk. & M.A. Curtis (≡ X. fimbriiformis) is accepted as a distinct species. Five new combinations are proposed: Cristinia decolorans for Irpex decolorans Cooke, Dentipellis ohiensis for Hydnum ohiense Berk., an earlier name for Dentipellis dissita (Berk. & Cooke) Maas Geest., Odonticium depauperatum for Irpex depauperatus Berk. & Broome, Peniophorella tessulata for Kneiffia tessulata Berk. & M.A. Curtis, an earlier name for Peniophorella rudis (Bres.) K.H. Larss., and Schizopora archeri for Irpex archeri Berk.
