Description
Tapinella atrotomentosa, also known as Paxillus atrotomentosus or Velvet Rollrim, is a large or massive agaric with a brown cap, buff gills, and a dark brown, velvety, sometimes eccentric stem. The mushroom grows singly or in groups or clumps on decaying conifer logs, stumps, roots, or partially buried wood.

Cap initially broadly convex, later flat or shallowly vase-shaped, dry, densely to finely velvety, brownish yellow to yellow-brown or reddish-brown in youth, typically darkening with age. Margin initially inrolled, often developing wide scalloping in maturity. The flesh is thick and firm and whitish to yellowish coloured. Gills decurrent (running down the stem), cream-yellow and forked, becoming ochre and spotted rust with age. Stem equal or occasionally swollen in the middle, sometimes off-centre or even lateral, thick and sturdy, whitish near the top but velvety brown to blackish-brown fuzz covers the lower part. The stem has no ring. Spore print sienna-brown.

Microscopic Features: The spores are ellipsoidal, smooth, measuring 5-6 x 3-4.5┬Ám.

Synonyms: Paxillus atrotomentosus is an older name.
