Abstract: Clitocybe polygonarum Laursen, O.K. Miller & H.E. Bigelow (Tricholomataceae) from arctic Alaska is transferred to Lepista (Fr.) W.G. Sm. as Lepista polygonarum(Laursen, O.K. Miller & H.E. Bigelow) Harmaja, comb. nov. The taxonomy of the species group that includes L. polygonarum is briefly discussed. The name Tricholoma multiforme has been incorrectly attributed to Romell as a new species. It is not synonymous with L. polygonarum. The nomenclature of Agaricus multiformis Schaeff. and Cortinarius multiformis Fr. is clarified. Mycena lammiensis Harmaja (Mycenaceae) is transferred to Prunulus Murrill, a segregate genus comprising species around M. pura (Pers. : Fr.) Kumm., as Prunulus lammiensis (Harmaja) Harmaja.
