Name in North American Boletes: Leccinum chalybaeum
- Species 2: scabrum var. chalybaeum
Tells: Very firm, shorter salt & pepper stem. Flesh bruises pinkish, aging toward dark purplish gray. Whitish pores are depressed by the stem & bruise olive/brownish. Likes sandy soil near oak.
Other Information: Cap is viscid when fresh (often shiny when dry). Cap color starts pinkish buff & ages toward dingy yellow brown, often w/”steel gray” tints (esp. by the edge). A southern species. It’s not “chalcybeum,” “chalcybaeum”, or “chalybeum” but enough people misspell it to enter the keywords [laugh].
