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, oft.cn 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 I line 

 thick. 



Rich soil along gutters or in canons. Pasadena. January. 

 McClatchie. 



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, .0005 to .0006 in long, .00035 to 

 0004 broad. 



Pileus 4 to 6 lines broad; stem about 1 in. long, I line thick. 

 On dung. Pasadena. July. McClatchie. 



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 calyptratl's. 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-fiocculent 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 .0008 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. 

 E. Bartholomew. 



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 the stem 

 is similar to that ascribed to the stem of C. stcrquilinus Fr., but our 

 plant differs from that in its calyptra and in the absence of an an-
