Polyporus badius, commonly known as the black-footed polypore, is a species of fungi in the genus Polyporus. This species causes a white rot of dead hardwoods and conifers.

Description

[edit]

Fruiting bodies of this species tend to be erect, growing solitary of in groups, sometimes with two or more fruiting bodies arising from a common stipe. The cap is round or kidney-shaped, often lobed or with a wavy margin. When young, the fruiting bodies are convex, then become flat or funnel-shaped in maturity, having dimensions of 5 to 25 cm (2.0 to 9.8 in)* by 1-4 mm thick. The upper cap surface is smooth, glossy, and with radial wrinkles when old. The color of the cap is brown, often darker in the center of the cap and lighter-colored at the margins. The lower surface is white or cream-colored, yellowing when old. Pores are round, 6-8 per mm, with decurrent tubes. The stipe, attached centrally or laterially, is 2 to 8 cm (0.79 to 3.15 in)* long by 0.5 to 1.5 cm (0.20 to 0.59 in)*thick, velvety and dark brown to blackish brown, black and longitudinally wrinkled when old.[1]

Microscopic features

[edit]

Spores are ellipsoid or cylindrical, hyaline, smooth, and 7.5-9 x 3-5 µm.[2] The basidia are club-shaped with a narrow base, and have dimensions of 20–30 × 7–9 um.[2]


Habitat and distribution

[edit]

This species grows on standing or fallen trunks and branches of various hardwood genera, including Acer, Aesculus, Alnus, Betula, Castanea, Fagus,Fraxinus, Populus, Prunus, Robinia, Quercus, Salix, Tilia and Ulmus.[2]
