COPRINUS VOLUTUS Copel. 



Coprinus volutus is characterized by having a pileus from 

 ■1 to 1.5 centimeters wide, being thin, naked, early explanate 

 and later revolute or involute. It turns gray to black and the 

 flat disk is ferruginous and warty. The gills are free, but very 

 close and at first obtuse at both ends, soon splitting from the. top 

 of the pileus, but not from the margin. The spores are black, 

 narrowly ovate and 12 to 13 by 6.5 microns. The stipe is 4 

 centimeters high, 1 to 1.5 millimeters thick, slightly attenuated 

 upward, and is white, naked, and hollow. The fungus grows on 

 rotted leaves. 



Coprinus fimbriati^s B. et Bt., Coprinus friesii Quelet. (Fig. 

 10) , and Coprinus nehulosus ZoU, may also be found. The first 

 two are commonly found growing on decaying Cocos nucifera 

 Linn, trunks. 



Genus PANAEOLUS 



Gills not deliquescing, not waxy, united above to the hymeno- 

 phore. Cap fleshy, not striate, with variegated gills exceeding 

 the margin. Spores globose to elliptic. Stipe not annulate. 



The descriptions given have been primarily taken from those 

 by Copeland.* 



PANAEOLUS PANAIENSE Copel. 



Panaeolus panaiense has a pileus which is 7 centimeters or 

 less wide, conical, tawny, and fleshy. The surface is flocculose 

 when dry and like blotting paper when wet. It has a fugacious

 are elliptical, 7.5 to 9 by 5.5 to 6.5 microns, and appendiculate. 

 The stipe is 12 centimeters or less high, 1 centimeter thick, 

 being equal, solid, and brittle. This species grows on horse 

 manure.

Panaeolus psedopapilionaceus has a pileus 1.5 to 3 centi- 

 meters wide, hemispherical, without umbo, whitish, not zonate, 

 dry, naked, and subfleshy. Its gills are narrowly adnate.
