Annual, sessile, fan-shaped (attached to the substrate by one side), rarely solitary—as a rule, fruiting bodies of the pubescent trametes form an imbricate structure, fusing at the margins or overlapping. The diameter of a single fruiting body is 3–10 cm, thickness 0.5–1.5 cm. Surface zoned, tomentose, densely covered with bristly hairs. Coloration variable, from light, almost white or yellowish, to light ashen; generally lighter at the periphery, darker near the point of attachment to the substrate.
Hymenophore tubular (located on the underside of the "cap"). Tubes short (up to 5 mm long), pores angular, losing their geometric shape with age. The tubular layer is initially white, gradually darkening to brownish with age. Due to the tendency of the pubescent trametes to form indistinct fused clusters, the hymenophore of what appears to be a single fruiting body may consist of several layers of different ages.
