When dried, it is wrapped inward, the bottom edge of the cap has a lighter color. The cap reaches 10cm in diameter. Thickness – 1cm. Fruit bodies in the form of caps with a lateral and central peduncle.

Leg: -1-4 cm long and 1.5 cm thick, the same color with the cap, pubescent.

Pulp: up to 2mm thick. The lower layer is hard, fibrous, the upper layer is softer, felt. Light yellow-brown Onnia Felt in the upper part of the leg has a light metallic shade. The tubular layer runs down to the leg up to 5 mm thick. The pores are rounded, with a pale brown surface, 3-5 pieces per 1mm of the mushroom surface. The edges of the pores are occasionally covered with a white coating.

Hymenophore: initially, the surface of the hymenophore is yellow-gray-brown with age, acquires a darker brown color.

Distribution: Found at the base of trunks and on the roots of growing trees in undisturbed mixed spruce forests. Wood-destroying mushroom, develops on the roots of larch, pine, spruce.
