Saprotroph. It grows near the roots of trees, on dry stumps, rotten wood of various species, on small-sized deadwood of deciduous species in broad-leaved and mixed forests. Found on decaying live trees. Prefers oak, birch, maple, poplar, beech wood.
Depending on the region, it occurs in August-September, until November. Regions: Europe, England, North Africa, Asia, China, Japan. Recorded in Our Country, Belarus.

Some sources indicate Tuberous Pluteus (Pluteus semibulbosus) as a synonym for velvety-legged Pluteus (Pluteus plautus). However, Plyutei velvety-legged is distinguished by the somewhat larger size of the fruiting bodies, the velvety surface of the cap, which becomes finely scaly with age, and by microscopic features.
