Pseudotricholoma is a genus of fungi in the family Tricholomataceae. The genus contains three species known from North America. Europe, and the Azores. Basidiocarps (fruit bodies) resemble those of the genus Tricholoma, with a dry fibrillose pileus and white to brown lamellae that have adnate to emarginate attachment and stain reddish when damaged, eventually turning black. Microscopically, the basidiospores are smooth, ellipsoid to ellipsoid-oblong, thin-walled and amyloid. Cheilocystidia are rare to absent and pleurocystidia are absent.

Pseudotricholoma is a genus of fungi in the family Tricholomataceae. The genus contains three species known from North America. Europe, and the Azores. Basidiocarps (fruit bodies) resemble those of the genus Tricholoma, with a dry fibrillose pileus and white to brown lamellae that have adnate to emarginate attachment and stain reddish when damaged, eventually turning black. Microscopically, the basidiospores 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. They are probably biotrophic, and may be ectomycorrhizal.
==Etymology== Pseudotricholoma means "false Tricholoma".
