PANAEOLUS INTERMEDIUS. Pileus campanulate or convex, even, 
glabrous, moist or hygrophanous, grayish-brown ; lamellae ascend- 
ing or subarcuate, subdistant, adnate, black* when mature ; stem 
slender, often elongated, hollow, grayish-brown, white-pruinose at 
the top; spores oblong-elliptical, .0005 to .0006 in. long, .00025 to 
.0003 broad. 
Pileus 6 to 12 lines broad; stem 2 to 4 in. long, .5 to 1 line 
thick. : 
Rich soil along gutters or in cafions. Pasadena. January.

_ The margin of the pileus does not extend beyond the lamellae, 
and this character with the slender stem suggests the genus 
Psathyrella, but because of the absence of striae on the pileus it 
seems best to refer the plant to the genus Panaeolus. 
PANAEOLUS DIGREssUS. Pileus hemispherical or convex, gla- 
brous, bay-red; lamellae very broad, plane, distant, adnate, pur- 
_plish black with a white edge; stem short, floccose-fibrillose 
toward the base, striate at the apex, hollow, a little paler than the 
pileus ; spores broadly elliptical, .o005 to..0006 in long, .00035 to 
.0004 broad. 
Pileus 4 to 6 lines broad; stem about 1 in. long, 1 line thick.

This plant also diverges from the generic character in its 
lamellae extending quite to the margin of the pileus, and in its 
unpolished stem. 
Coprinus caLyprratus. Pileus when mature adorned with a 
few grayish floccose scales and crowned with a persistent stellately 
Split membranous dingy-yellow or subtawny calyptra, radiate 
‘Striate to the disk, grayish-flocculent along the ridges of the striae, 
blackish ; lamellae free, dark lead color becoming black; stem 
equal, hollow, white, becoming blackish in drying except at the 
base, neither annulate nor -distinctly volvate; spores elliptical, 
black, .0006 to .o008 in. long, .00045 to .0005 broad. 
Pileus about 2 in. broad; stem 3 to 4 in. long, 2-to 3 lines 
thick. Open cultivated ground. Rockport, Kansas. August.

This species is well marked by the persistent membranous 
calyptra that adheres to the summit of the pileus. Its margin is 
split into four to six broad rays. The change of color in thestem 
is similar to that ascribed to the stem of C. sterguilinus Fr., but our 
Plant differs from that in its calyptra and in the absence of an an-
