''Pseudotricholoma'' is a genus of fungi in the family Tricholomataceae. The genus contains two species known from the Canada, the United States and Europe. ''Pseudotricholoma'' was described the mycologists Marisol Sánchez-García and P. Brandon Matheny in 2014 with ''Pseudotricholoma umbrosum'' as the type species.〔 ''Pseudotricholoma'' has a tricholomatoid stature, a dry fibrillose pileus and white to brown gills that have adnate to emarginate attachment and stain reddish when damaged, eventually turning black. The spores are smooth, ellipsoid to ellipsoid-oblong, thin-walled and amyloid. Cheilocystidia are rare to absent and pleurocystidia are absent. The pileipellis is a cutis and clamp connections are present. Species in ''Pseudotricholoma'' are found on soil in grasslands and woods in the Northern Hemisphere. They are probably biotrophic, and might be ectomycorrhizal.〔 Macroscopically, it resembles ''Tricholoma'' and can be differentiated by its red staining gills. Phylogenetically, it is closely related to ''Tricholoma'' and ''Leucopaxillus''.〔 == Etymology == ''Pseudotricholoma'' means "fake ''Tricholoma''". 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Pseudotricholoma」の詳細全文を読む スポンサード リンク
