EDIBLE AND POISONOUS MUSHROOMS OF CANADA
nearly white at first, becoming flesh-colored, stipe 1 )/2-2!/2 in- long ^6"!^ in.
thick, equal, smooth, somewhat striate, yellow, white-mycelioid at base, hollow,
central, spores pink, angular, 10-12 X 6-7 fi.
Singly or in groups in swampy woods. Aug.-Sept.
A rather distinctive species in which the whole plant is more or less
yellowish and the pileus is scaly.
NOLANEA
Nolanea includes a group of species with angular pink spores, closely
related to Leptonia. In the young fruiting bodies the margin of the pileus is
straight on the stipe rather than inrolled and the mature pileus is usually more
or less conical to campanulate. This is the principal distinction from Leptonia
although in Nolanea the pileus is usually umbonate or papillate whereas in
Leptonia it is umbilicate or depressed. The lamellae are adnate to adnexed,
often seceding. The cartilaginous stipe distinguishes it from Entoloma.
The species are not well known and are small and of no value as food.
The one described here is fairly common.
NOLANEA MAMMOSA (Fr.) Quel.
pileus J/^-1 1/2 in. broad, conic to campanulate, umbonate, slightly hygro-
phanous, umber when moist, becoming grayish brown to fuscous, innately
fibrillose and shining when dry, margin decurved. flesh thin, brownish to
whitish, odor and taste of rancid meal, lamellae adnate, seceding, subdistant,
broad, at first pale gray, then becoming pinkish, edges often uneven, stipe
2-31/2 in. long, Jf6~% in- thick, equal, sometimes compressed, glabrous,
pruinose at the apex, brownish gray, hollow, spores pink, angular, 9-11 X
6-7 M-
In groups on the ground in woods or grassy places. July-Sept.
N. fuscogrisella Peck is somewhat similar but is usually smaller; it has
smaller spores, and the lamellae are at first white rather than gray. N. papillata
Bres. is also very close to A^. mammosa and is separated principally on the
basis of smaller size and closer lamellae.
