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.[1]
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.[1]
Macroscopically, it resembles Tricholoma and can be differentiated by its red staining gills.
Phylogenetically, it is closely related to Tricholoma and Leucopaxillus.[1]
