the allied genera, Pholiota, Hebeloma and Naucoria. From Pholiota 
it is especially separated by the slight development of the veil which 
is merely fibrillose or entirely wanting. It never forms a persistent 
membranous collar on the stem. From Hebeloma it may be distin¬ 
guished by the absence of a sinus at or near the inner extremity of 
the lamellae, by the absence of white particles or mealiness from the 
upper part of the stem and by the brighter or more distinctly fer¬ 
ruginous or ochraceous color of the spores. From Naucoria the 
fleshy or fibrously fleshy stem affords the most available distinguish¬ 
ing character. The genus belongs to the Ochrosporae or ochraceous 
spored Series, but the spores of its species vary in color from ochra¬ 
ceous or tawny-ochraceous to ferruginous or fuscous-ferruginous. 
The three things to be especially kept in mind in order to recognize 
the species are the color of the spores, the adnate or decurrent but 
not clearly sinuate lamellae and the fleshy or fibrously fleshy stem 
without a membranous annulus. 
Our species are mostly of medium size, none being very small and 
one only meriting the appellation large. They appear chiefly in late 
summer or in autumn and grow in woods or in wooded regions either 
on the ground or more often on decaying wood. Many are grega¬ 
rious or caespitose in their mode of growth. Some have a bitterish 
or unpleasant flavor and none of our species has yet been classed as 
edible. Fries arranged the species in five groups, of which the 
names and more prominent characters are here given: 
Gymnotce. Pileus dry, often squamulose; veil none; spores fer¬ 
ruginous. 
Lubricce. Pileus viscose, glabrous, the pellicle subseparable; veil 
fibrillose; spores ferruginous or fuscous-ferruginous. 
Udce. Pileus moist or slightly viscid in rainy weather, glabrous, 
the cuticle not separable; veil evident, appendiculate. 
Sapinece. Pileus not viscose; lamellae at first yellow or yellowish; 
veil almost none or fibrillose, not appendiculate; spores tawny or 
ochraceous. 
Sericellce. Pileus dry or at first viscid, slightly silky. 
At present, no representatives of the first and the last tribes are 
known to belong to our State. The three remaining tribes are repre-
