European Mycology

It inhabits Sweden and France, on old Willows; it is easily distinguished by its anise-like odor. When young it is white, then reddish, scabrous rough and zoned above, and sordidly yellowish inside. Sometimes it is odorless: according to Bulliard.

16. confragosa, with a leathery-corky, conate-scabrous fused and rough, brick-brown pileus, with labyrinthine, ashy-gray sinuses. Syn. fung. p. 501. Bolt. Fung. t. 160. (as a Boletus).

Boletus labyrinthiformis. Bull. p. 357. t. 491. f. 1.

On the trunks of the Wild Service tree (Sorbus torminalis). Sub-imbricated, with concolorous zones. The sinuses, which are reddish according to Bolton, and gray according to Bulliard, are quite large and varied in shape.

17. gibbosa, sub-imbricated, rather flat on both sides, obsoletely zoned, whitish-pale, gibbous humped and protruding at the base, with pale, narrow, straight sinuses. Syn. fung. p. 338. Boletus suberosus. Linn. B. imberbis Bull. t. 445. f. 1. (poor, drawn too thin).

It inhabits various regions on trunks, to which it is attached at the base in the form of a handle; sometimes a span the distance between the tip of the thumb and the little finger wide, but generally a hand-breadth wide, 1/2 inch thick, of a hard, dry substance. The surface turns greenish in old specimens.

The sinuses at the base of the pileus are almost as they are in D. quercina, and toward the circumference they are sub-pore-like.
