⚠️
Caution: Never consume any wild fungi unless you are 100% certain of its identity and have consulted with an expert mycologist. Many toxic species closely resemble edible ones.

Species Description
Description
One of the most unmistakable and "shaggy" mushrooms in the forest, the Old Man of the Woods looks like it belongs in a black-and-white film. It is covered in soft, dark, woolly scales that stand out sharply against a pale background, giving it a rugged, weathered appearance that mimics a piece of charcoal or a pine cone.
Habitat in the ANF
In the Allegheny National Forest, this mushroom is a common sight from July through September. It is mycorrhizal, forming symbiotic bonds with hardwood trees, particularly Oaks and Maples. It prefers well-drained soil and is often found on mossy banks, along the edges of hiking trails, or nestled in the leaf litter of mature deciduous stands.
Ecology and the Color-Shift Defense
The Old Man of the Woods is a member of the bolete family, meaning it has pores instead of gills. One of its most fascinating ecological traits is its dramatic color reaction to injury. If you slice the flesh or bruise the pores, it will quickly turn pinkish-red, then slowly transition to a deep, coal-black. This oxidation process is thought to be a chemical defense that makes the mushroom less appetizing to certain insects or larvae.
Identification
The Cap: 2 to 6 inches wide, covered in thick, dark grey to black woolly scales or tufts on a lighter white-to-grey background.
The Pores: The underside features a spongy layer of greyish-white pores that turn black as the mushroom ages.
The Stem: The stalk is tough, shaggy, and shares the same grey-black color and "woolly" texture as the cap.
The Flesh: When sliced, the white interior flesh will stain reddish-pink before eventually turning jet black.
The Spores: Unlike most boletes which have olive or brown spores, this species has black spores, which often stain the stem and the surrounding area.
