BOLETINELLUS MERULIOIDES (Schw.) Murr. Edible
Figure 309, page 213
PILEUS 1 1/2-5 in. broad, circular to reniform, depressed towards one side,
olive-brown to yellowish brown or reddish brown, finely tomentose to gla-
brous, dry, margin usually indented and inrolled, finally spreading, even.
FLESH soft but rather tough, yellowish to pinkish near the surface, sometimes
turning bluish green when cut, taste mild, odor none or of raw potatoes.
TUBES decurrent, strongly radiating, partly lamellate, short and wide, yellow
with a greenish tinge, becoming more ochraceous in age. stipe excentric or
lateral, 1/2-2 in. long, i/^-% in. thick, nearly equal or slightly swollen at the
base, expanding into the pileus above, reticulate and yellowish above, reddish
brown or olivaceous brown to blackish and short-tomentose below, solid.
spores yellowish to brownish-ochraceous, eUipsoid, smooth, 7.5-10.5 X 5.5-
7.5 M.
On damp ground in woods or open places, usually gregarious and gen-
erally associated with ash. July-Sept.
This species is not likely to be confused with any other. It has been widely
known also under the name Boletinus porosus (Berk.) Pk. It resembles Paxillus
involutus in color and shape and shows relationships with the genus Paxillus.
It is said to be edible but it is not a very attractive fungus.
BOLETINUS CAVIPES (Opat.) Kalchbr. Edible
Figures 311, 312, page 213
PILEUS 1-4 in. broad or sometimes larger, broadly convex, subumbonate,
tawny brown to yellowish brown, sometimes tinged reddish or purphsh, fibril-
lose-squamulose. flesh yellowish, taste farinaceous to bitter, tubes decurrent,
radiating, at first sulphur-yellow becoming dingy ochraceous in age. stipe 1-3
in. long, 54-1/2 in. thick, enlarged below up to 1 1/2 in., usually more or less
reticulate above the annulus, yellow above the annulus, concolorous with the
pileus below, at first stuffed, soon hollow, annulus white to ochraceous,
dehcate, evanescent, sometimes partly adhering to the margin of the pileus.
spores olivaceous-ochraceous in a fresh deposit, changing to yellowish-ochra-

Singly or gregarious in damp woods or swamps, associated with larch or
pine. Sept. and Oct.
This species is usually a rich tawny brown but one collection was a bright
golden yellow. It seemed to be the same in every other respect and was growing
along with typical specimens. The hollow stipe is the chief diagnostic character.
