mose or strigose-hairy appearance. The color of the pileus is often 
paler toward the base than it is on the margin. 
Claudopus variabilis, /’r. 
Variable Agaric. 
Agaricus variabilis, Pers. Agaricus sessilis, Bull. Agaricus niveus, 
Sow. 
Pileus thin, one-half to one inch broad, at first resupinate, then 
reflexed, sessile or with a very short stem, tomentose, white; lamella 
rather broad, thin, radiating from a lateral or an eccentric point, dis- 
tant, white becoming pink; spores even, elliptical, .00025 to .0003 in. 
long, about half as broad. 
Decaying wood and dead branches. Adirondack mountains. July 
to October. Buffalo. G. W. Clinton. 
A small and not common species. The thin pileus is often attached 
to its place of growth by white tomentose filaments, and the point to 
which the lamelle converge is also sometimes tomentose. , 
Claudopus depluens, /’7. 
Rainy Agaric. 
Agaricus depluens, Batsch. 
Pileus thin, one-half to one inch broad, at first resupinate, then’ 
reflexed, variable in form, sessile or with a short stem, slightly silky- 
tomentose especially toward the base, white or whitish, sometimes 
slightly tinged with pink; lamelle broad, subdistant, whitish, becom- 
ing pink; spores angulated, .0004 to .00045 in. long, .0003 broad, 
usually containing a single large nucleus. 
Decaying wood. Catskill mountains, Gansevoort and Sterling. 
July and August. 
This species, like the preceding one, which it closely resembles and 
from which it is separated by the character of the spores, is very 
variable. In our specimens the pileus is white, but it is sometimes 
described as tinged with red or gray. It is also said to grow upon the 
ground and on mosses, but our specimens grew upon decaying wood. 
In both these particulars they agree with the figure of the species in 
Mycological Illustrations. 
Claudopus Greigensis, P/. 
Greig Agaric. 
Pileus very thin, convex, five to ten lines broad, hygrophanous, 
grayish-cinnamon color and striatulate when moist, silky-fibrillose 
when dry; lamellae subdistant, scarcely reaching the stem, grayish 
becoming dingy-pink; stem short, about one line long, solid, curved, 
fibrillose below, with an abundant white radiating mycelium at the 
base; spores angulated, .00035 to .00046 in. long, .0003 broad, usually 
containing a single large nucleus. 
Much decayed wood. Greig. September. . 
This species is intermediate between the preceding and the follow- 
ing one, but it is more closely related to the latter, from whichitis * 
distinguished by the striatulate pileus and free lamelle.
