AGARICUS. 



XXI. Agaric us (Inocybe) lanngi- 

 nosus. One-fourth natural size. 



inocybe. Subgenus XX. INOCYBE (ft, fibre; K vM, head). Fr. Syst. 



Myc. i. p. 254. Universal veil somewhat fibrillose, concrete with 



the cuticle of the pileus, often free 

 at the margin, in the form of a cor- 

 tina. Gills somewhat sinuate (but 

 they occur also adnate and in two 

 species decurrent), changing colour, 

 but not cinnamon-pulverulent. Spores 

 often rough, but in others even, more 

 or less fuscous-ferruginous. Fr. Hym. 

 Eur. p. 226. 



Inocybe (with Hebelomd) corresponds 

 with Tricholoma. Inocybe and Hebe- 

 loma have some common features, but 

 they are really very distinct. Inocybe 

 is readily distinguished by the silky- 

 fibril lose covering of the pileus, which 

 never has a distinct pellicle, by the 

 veil which is continuous and homo- 

 geneous with the fibrils of the pileus, and by the ferruginous- 

 fuscous spores. All grow on the ground. They are (mostly) 

 strong-smelling (commonly nauseous). None are edible. 



The position of Inocybe among Dermini is not satisfactory. It 

 forms a very natural group of itself, and is, in many respects, not 

 properly allied to Dermini. It might form a distinct genus in- 

 termediate between the Agarici and the Cortinarii. 



I. Squarrosi (squarrose). Pileus at the first squarrose, somewhat fuscous, 

 and stem scaly of the same colour. 



II. Laceri (torn). Pileus torn into scales or fibres (not split into cracks) ; 

 stem coloured, paler than the pileus, fibrillose. 



III. Rimosi (cracked). Pileus longitudinally fibrous, soon cracked and here 

 and there adpressedly scaly ; stem -whitish, slightly tinged with the colour of 

 the pileus, fibrillose. Many of them become yellow when old. 



IV. Velutini (velvety). Pileus not cracked, the cuticle fibrillose-ivoven, be- 

 coming even or adpressedly scaly, disc even; stem polished, smooth, whitish, 

 mealy at the apex. 



V. Viscidi (viscid). Pileus becoming even, viscid (with one exception). 



I. SQUARROSI. Pileus at the first squarrose, &>c. 



525. A. hystrix Fr. Pileus 5-7.5 cent. (2-3 in.) broad, mouse- 

 colour, fleshy, firm, but not compact, convex then flattened, ob- 

 tuse or slightly gibbous, orbicular, squarrose with revolute floe-
