Field Notes
Description:
This distinctive polypore is typically a fall species, often found on decaying hardwood logs across the continent. Its stem is black, and its dark reddish brown cap is fairly large, measuring up to 20 cm. The smaller Polyporus varius has a paler cap, and is usually found on smaller hardwood branches and sticks.
Description:
Ecology: Saprobic on decaying hardwood and conifer wood; causing a white rot; growing alone or in small groups; fall and winter (though I have found it in the spring); widely distributed in North America.
Cap: 4-20 cm; broadly convex to shallowly vase-shaped; round in outline, kidney-shaped, or lobed; dry; smooth; dark reddish brown to dark brown, often paler towards the margin (rarely pale overall, with a reddish brown center).
Pore Surface: White, becoming dingy in age; often running down the stem; pores circular and very tiny (4-6 per mm), not easily separable from cap.
Stem: Central or off-center to lateral; 1-6 cm long; 5-1.5 cm wide; equal; dry; pale at the apex but soon black nearly overall; tough.
Flesh: White; thin; very tough.
