Saprophytic Fungi of Eastern Iowa. 191 



at lenofth smooth, the flesh thin, concolorous: lamellae seced- 

 ing, close but not crowded, brown, often beaded with drops of 

 moisture; stipe hollow, more or less tibrillose, brownish at 

 base, yellow above. 



Height 4 '-6'. Pileus3'-4'. Spores elliptic, .005 x -009 mm. 



Not common. Distinguished from the preceding species 

 by the pileus not scaly, campanulate and thin. In No. 39 

 the whole make-up is stout and firm; here, just the reverse. 



Found in unkept yards and lawns about the city. Inedible. 



41. Agaricus candolleanus, Fr. 



Pileus yellowish-white or dusky, thin, from campanulate- 

 convex at length expanded, smooth, hygrophanous; lamellae 

 round-adnate, crowded, at first violet, then brownish to cinna- 

 mon; stipe white, hollow, very frail, striate above. 



Height 2 '-5'. Pileus 2 '-4'. Spores elliptic, .004 x -007 

 mm. 



Very common from May to October about decaying stumps 

 or roots, anywhere on lawns, in pastures and in woods, and 

 very well defined. In large specimens the lamellae seem nar- 

 row for the size of the pileus, and the margin becomes refiexed 

 and lacerate in wet weather. The spores by reflected light 

 show the rich purplish-brown characteristic of the series, but 

 on the microscope the purple tints disappear, and only a 

 beautiful brown {sfadiccus) remains. Usually in dense clus- 

 ters, sometimes solitar}' or gregarious. Not edible, though 

 the taste is pleasant and the odor mealy. 



Subgenus Psilocybe, 



Pileus more or less fleshy, the margin at first incurved. 

 Veil none. Stipe subcartilaginous. 



42. Agaricus spadiceus, Fr. 



Pileus hygrophanous, brown, becoming pale when dry, 

 fleshy, convexo - plane, smooth; lamellee round-adnate, dry, 

 close, white, then rusty brown; stipe hollow, tough, smooth at 

 the apex.
