Polyporus brumalis, commonly known as the winter polypore, is a species of fungi in the genus Polyporus. It is distinguished by other members ofPolyporus by its pale large stalk and large pores. Like other members of the Polyporus genus, it causes a white rot in dead hardwoods
Description[edit]
Fruitbodies are erect, solitary or gregarious, centrally stalked. Cap round, flat to somewhat umbilicate, 2–8 cm in diameter, 2–4 mm thick, thin margin involute when dry, surface smooth, edge ciliate only when young, greyish brown to umber or blackish brown, lower surface white to cream, pores round or angular, thin-walled, 2–3 per mm, becoming larger and more elongated towards the center. The stalk is 2–6 × 0.3–0.8 cm, at first floccose and ochraceous, later becoming smooth and pale brown or grayish brown.[1]
Microscopic features[edit]
The spores are cylindrical or allantoid hylaine, smooth, with dimensions of 6–7 × 2–2.5 µm. Basidia are club-shaped, 4-spored, and have dimensions of 16–22x5–6.5 µm.[2]
Habitat and distribution[edit]
This species is found on the dead wood of various hardwood genera, such as Acer, Alnus, Arbutus, Betula, Corylus, Crataegus, Fagus, Fraxinus,Juglans,Malus, Populus, Prunus, Pyrus, Rhamnus, Robinia, Rubus, Quercus, Salix, Sorbus, Tilia, and Ulmus, and more rarely on conifers such as Cryptomeria, Juniperus, Picea, and Pinus.[2]
