Liu and T. nigrosquamosa P. G. Liu. The new variety is T. bambusina Hongo var. megaspora P. G. Liu. T. lividipileata is close to T. totilivida (Murrill) Singer, but distinguished from the latter by the livid pileus, whitish to yellowish lamellae and stipe, and absence of pleurocystidia. T. nigrosquamosa P. G. Liu is close to T. decora (Fr.) Sing, but distinguished from the latter by its pale pileus with black to nigrescent scales and larger spores 7.8-11×5-7μm. The new variety, T. bambusina var. megaspora P. G. Liu, is distinct from the original variety in the larger spores ((4.5-)6-8×4-6μm) and its occurrence on the stump of Lithocarpus, not on bamboo. Tricholomopsis araucariae Singer, T. flavissima (Smith) Singer and T. radicata (Pk.) Singer are new records to China.
