by Michael Kuo
Trametes pubescens is a small, thin polypore with a cream-colored, finely velvety cap surface that lacks strongly contrasting zones of color (most other turkey tail-like species of Trametes are decidedly zoned). Its pore surface becomes yellowish with age, and features 3-5 angular pores per mm. Trametes pubescens is a decomposer of the deadwood of hardwoods, widely distributed on our continent.
Ecology: Saprobic on the deadwood of hardwoods (rarely reported on conifer wood); annual; causing a white rot; growing in clusters on logs and stumps; summer and fall; widely distributed across North America.
Cap: Up to 8 cm across and 5 cm deep; semicircular, irregularly bracket-shaped, or kidney-shaped; sometimes fusing laterally with other caps; velvety to finely velvety, sometimes becoming nearly bald with age; often finely, radially lined and furrowed, especially on the margin; cream colored; sometimes with faint textural zones but without contrasting zones of color.
Pore Surface: Creamy, becoming yellowish with age; with 3-5 angular pores per mm; tubes to 6 mm deep.
Flesh: Insubstantial; whitish; tough and corky.
Odor and Taste: Not distinctive.
Chemical Reactions: KOH on flesh yellow.
Spore Print: White.
Microscopic Features: Spores 5-7 x 1.5-2 µ; smooth; cylindric; inamyloid. Cystidia absent. Hyphal system trimitic.
