EDIBLE AND POISONOUS MUSHROOMS OF CANADA<br />
Scattered or in groups on the ground in woods, uncommon. Sept.-Oct.<br />
This is one of the largest of the hebelomas and has been included as a<br />
representative of the genus. The floccose-scaly stipe and broad lamellae<br />
together with the large size are the distinguishing characters. Definite information<br />
as to its edibihty is lacking but it is not recommended since other members<br />
of the genus are known to be poisonous.<br />
CONOCYBE<br />
Conocybe includes a group of small, fragile, Mycena-\\kt mushrooms with<br />
rusty brown spores. They were formerly included in the genus Galera but this<br />
name cannot be used under the International Code of Nomenclature because<br />
the name had been given earlier to a genus of flowering plants. The old genus<br />
Galera has been divided into two genera based on the structure of the cuticle.<br />
In Conocybe the cuticle is cellular and in Galerina it is filamentous. The species<br />
are unimportant as food because they are so small and fragile and they are<br />
difficult to identify. One species is included here because it is commonly found<br />
on lawns and is fairly easily recognized.<br />
CONOCYBE CRISPA (Longyear) Singer<br />
Figure 385, page 283<br />
PILEUS Yi-l Va in. broad, conic to campanulate, sometimes slightly umbonate,<br />
striate to rugulose, glabrous, atomate, whitish buff", more brownish on<br />
disk when moist, flesh thin, membranous, lamellae adnexed, close to sub-<br />
distant, narrow, crisped and interveined, ferruginous brown, stipe 1 y^-2> in.<br />
long, about i/fg in. thick, white, or tinged ochraceous, equal, shghtly bulbous at<br />
base, hollow, spores ellipsoid to ovoid, rather variable, smooth, rusty brown,<br />
11-16(18) X 8-12 M-<br />
Gregarious on lawns and grassy places. June-July (Sept.).<br />
The distinctive character of this species is the crisped lamellae. A similar<br />
species in which the lamellae are not crisped is also common on lawns. It has<br />
been generally known as Galera tenera Fr., but according to Smith (1949) the<br />
true G. tenera is rare and the common species that has been called G. tenera is,<br />
in reality, Conocybe lactea (Lange) Metrod. Although this species is, perhaps,<br />
more common than G. crispa it was thought desirable to choose the latter as a<br />
representative of this group because it could be identified with more certainty.<br />
All the species of this group are too small and fragile to be of any value as food.<br />
