sometimes pinkish, unchanging, taste sweet and nutty, tubes adnexed to
nearly free, depressed around the stipe, at first white and stuffed, becoming
greenish yellow, stipe 2)/2-6 in. long, J^-1 1/4 in. thick, equal or swollen at the
base up to 2j4 in., reticulate, sometimes for the entire length, sometimes only
at the apex, whitish to yellowish or brownish, soHd. spores oHvaceous brown
to ochraceous brown, ellipsoid-fusiform, smooth, 13-18 (21) X 4-6 ju.
Solitary or gregarious on the ground in woods and open places. June-Oct.
B. edulis is one of the best edible fungi but it is difficult to find it free from
insect larvae in eastern Canada. In Europe it is a very well-known species and
has a good many common names such as cepe and Steinpilz. In some parts of
central Europe special trains used to and may still run from the cities in the
right season for people to go to the country and collect this bolete. It can be
shced and dried and retains its rich, nutty flavor when used in gravies or stews.
BOLETUS SUBVELUTIPES Peck Dangerous
Figures 321, 322, page 215
piLEUS 1 54-5 in. broad, convex, yellowish brown to reddish or dark
brown, sometimes paler or olivaceous toward the margin, at first somewhat
velvety-tomentose, becoming glabrous, flesh yellow, changing to blue when
wounded, taste mild, tubes adnexed, depressed around the stipe, red at the
mouths, elsewhere yellow, becoming blue when wounded, stipe 2-4% in. long,
V2-1 54 in. thick, equal or tapering upward, sometimes bulbous at the base,
more or less furfuraceous to nearly glabrous, with a red or yellow, coarsely
hairy tomentum at the base, reddish brown above, yellow at the apex, solid.
SPORES yellowish, elHpsoid-fusiform, smooth, 12-17 X 4.5-6 /x.
Usually sohtary or gregarious on the ground in mixed woods. July-Sept.
In several species the mouths of the tubes are red and some of these are
known to be poisonous. The species in this group are rather difficult to identify
and no species with red tube mouths should be eaten. This species, with the
furfuraceous, nearly equal stipe and colored tomentum at the base appears to
be the commonest one.
