CLASSIFICATION 325 



A. comptulus. — Cap 1-2 in. across, convex, then plane, silky or 

 smooth, \vhite ; gills flesh-colour, then reddish brown ; stem about 

 2 in. high, whitish, ring fugacious. 



Among grass. 



A. subgibbosus. — Cap up to i in. across, almost flat, subumbonate, 

 smooth, yellowish, edge fibrillose ; gills white, then greyish brown ; 

 stem about i in. long, ring fugacious. 



In woods, etc. 



PiLOSACE 



Cap regular, fleshy ; gills free from the stem ; general and 

 partial veil both entirely absent ; stem central, stout ; spores 

 purple-brown. 



Almost exactly resembles A. campestris in general appearance, 

 differing in the absence of a ring on the stem. 



A . algeriensis. — Cap hemispherical with the edge incurved, then 

 becoming depressed round the gibbous disc, and with the edge up- 

 turned and often splitting, snow-white, minutely silky, 3-4 in. 

 across ; flesh thick except at the edge, white ; gills distant from 

 the stem, narrow, slightly broadest in front, dark brownish purple ; 

 stem 2-3 in. long, equal, firm, even, silky, white, differentiated from 

 the flesh of the cap, solid, 2-3 in. long. 



This species has up to the present only been found in one locality, 

 near Scarborough, in this country. As it is difficult to distinguish 

 in the field from A . campestris, unless attention is paid to the 

 absence of a ring on the stem, it has possibly been passed over as 

 that species. 



On the ground among grass. 



Stropharia 



Cap regular, often rather fleshy and with a viscid pellicle ; gills 

 becoming dark brown or purplish ; stem central, with a distinct ring. 



Readily distinguished amongst the Porphyrosporcce by the gills 

 being attached to the stem and the ring on the stem. 



I. Cap viscid, at least iclieii damp. 



* Not groiving on dung. 



S. percevali. — Cap 1J-2 in. across, viscid, ochraceous, umbonate, 

 with a few white squamules which often disappear ; flesh dusky ; 

 gills greyish, then umber ; stem 2-^-, in. high, hollow, flesh dark, 

 pale above ring, transversely squamulose 1 clow. 



On rotten wood, sawdust, etc. 



S. versicolor. — Cap 1-4 in. across, scaly ; gills running down the 

 stem, pallid, then reddish brown : stem whitish, bulbous, ring 

 persistent. 



An imperfectl}' known fungus.
