Brown Birch Bolete
Leccinum scabrum
Type: Boletes (boletus)
Physical Characteristics
Cap: Brownish, convex to broadly convex, dry to slightly tacky surface. Pores: Whitish to grayish, bruising brownish or yellowish. Stem: Pale to brownish, tall and slender, tapers upwards, covered with small, dark scabers (dots or scales) which may be darker brown or black.
Habitat & Growing Conditions
Typically found on the ground in woodlands, often in association with birch, aspen, or oak trees.
Season & Fruiting Time
Summer to early autumn, especially after periods of rain.
Similar Looking Species
There are several other Leccinum species, many of which are very similar and difficult to distinguish without microscopic examination or specific host tree identification. For example, Leccinum holopus (White Birch Bolete) is paler, and Leccinum versipelle (Orange Birch Bolete) has an orange cap and usually darkens when cut.
Ecological Role
Mycorrhizal, forming a symbiotic relationship with trees such as birch, aspen, and oak, exchanging nutrients.
Safety reminder
AI mushroom identification is a best-effort estimate and can be wrong. Never use it to decide whether a mushroom is safe to handle or eat — always confirm with a qualified mycologist before any consumption.
