Sept.
Singly or gregarious on the ground in frondose or mixed woods. June-
This is a fairly common species and differs from the other Leccinums in
having yellow tubes. However, the slender, furfuraceous stipe, and other
characters seem to indicate that it is more closely related to Leccinum than to
Boletus.
STROBILOMYCES FLOCCOPUS (Vahl ex Fr.) Karst. Edible
Figure 348, page 235; Figure 425, page 302
pileus 2-5 in. broad, hemispherical to convex, dry, covered with large,
thick, erect, floccose, blackish brown scales, margin thick and irregular, appen-
diculate with scales and veil fragments, flesh whitish, soon reddening and
becoming black when wounded, mild, tubes at first whitish, changing color
like the flesh, adnate, depressed at the stipe, mouths rather large, angular.
STIPE 2-5 in. long, i4-% in. thick, nearly equal or somewhat enlarged at base,
colored like the pileus, floccose-tomentose from the remains of the veil, solid.
SPORES black in mass, globose, reticulate, 9-12 X 9-10 /x.

This species has been known under the name Strobilomyces strobilaceus
(Scop, ex Fr.) Berk., but S.floccopus is the correct name for it. It is sometimes
called the cone-like boletus or pine cone fungus, perhaps because of the
shaggy appearance caused by the large scale. It is a striking fungus but rather
unattractive in appearance. It is said to be edible but of indifferent quality.
