Pileus 6 to 12 lines broad; stem 1 to 1.5 in. long, 1 to 2 lines thick. 
Burnt ground or damp earth. Highlands of Orange county, Cats- 
kill mountains and Adirondack mountains. June to September. 
From F. carbonaria, of which it may perhaps be a mere variety, 
this is separated by its smaller size, whitish flesh and differently 
colored lamellae. The margin of the pileus is often paler than the 
central part. The surface is usually more or less defiled by dirt or 
other adhering substances that have been carried up in the growth of 
the plant. The mycelium commonly binds together a little ball of 
earth which clings to the bottom of the stem when the plant is pulled 
from the ground. Agaricus Ascophorus is merely a form of this 
species with the squamules of the stem wanting or inconspicuous. 
Udse. 
Pileus moist or slightly viscid in rainy weather, glabrous, the cuti¬ 
cle not separable; veil evident, appendiculate.

Alder Flammula. 
Hym. Europ. p. 248. Syl. Fung. Vol. v. p. 820. 
Pileus fleshy, at first broadly conical or convex, then broadly con¬ 
vex or nearly plane, glabrous or sometimes slightly silky-fibrillose 
on the margin, clear lemon yellow, rarely tinged with ferruginous in 
the center, moist, flesh yellowish, taste bitter; lamellae close, adnate 
or sometimes slightly rounded behind, pallid or yellowish becoming 
ferruginous; stem rather long, often curved or flexuose, fibrillose, 
hollow, yellowish becoming ferruginous or brownish-ferruginous 
especially toward the base; spores ferruginous, .0003 to .0004 in. 
long, .0002 to .00024 broad. 
Gregarious or caespitose; pileus 1 to 2.5 in. broad; stem 2 to 3 in. 
long, 2 to 4 lines thick. 
Ground or decaying wood of deciduous trees. Albany and Rens¬ 
selaer counties, Catskill and Adirondack mountains. September

The Alder flammula is a beautiful fungus. The color of the pileus 
is generally a uniform bright lemon yellow but sometimes it assumes
