Abstract

Three new species of Agaricales are described and illustrated from eastern Honshu, Japan: Boletus rhodocarpus sp. nov. (section Luridi), forming large, deep red basidiomata with a pileus covered with small, blackish brown scales, was found on ground in a highland forest dominated by Tsuga diversifolia and Abies veitchii: Phaeomarasmius laccarioides sp. nov. (subgenus Carpophilus), forming a squamulose-fibrillose, reddish brown pileus in which the pileipellis consists of chains of thick-walled sphaerocysts with heavily incrusting, brown pigment, was found on a fallen fruit of Liquidambar styraciflua; Pluteus phaeocephalus sp. nov. (subsection Hispidodermini of section Celluloderma), forming a dark brown, velvety pileus and a white stipe densely covered with dark brown punctate scales, was found on dead fallen twigs of Quercus serrata.
