264 FUNGUS-FLORA. 



ventricose, 2 lines or more broad, at first pale then flesh 

 colour; stem 1-2 in. long, 1-2 lines thick, almost equal or 

 slightly thinner downwards, even, nearly glabrous, pitch- 

 black, very slightly pruinose, rather tough, not straight, 

 hollow; spores elliptical, smooth, 7-8 X 5 /x. 



Agaricus (Nolanea) jpiceus, Kalchbr., Icon. Sel. Hym. Hung., 

 p. 23, lA. xi., fig. 2; Cke., Hdbk., p. 135; Cke., lUustr., 

 pi. 379a. 



Among grass. 



Smell strong, resembling cucumber or decaying fish. 

 Allied to N. pisciodora, but distinguished by the glabrous, 

 pitch-black pileus and stem when moist. 



Nolanea infula. Fr. 



Eemarkably tough. Pileus up to f in. across, membra- 

 naceous, conical then expanded, with a papilla or wart-like 

 umbo, shining, almost even, hygrophanous, dark grey when 

 moist, pale buff when dry ; gills adnexed, not 1 line broad, 

 closely crowded, snow-white then pink ; stem about 2 in. long, 

 rigid, glabrous, naked, brown, paler when dry, imperfectly 

 hollow. 



Agaricus infula, Fries, Sp., i^. 8; Cke., Hdbk., p. 135; 

 Fries, Icon., t. 100, f. 1. 



On the ground in copses, &c. 



Inodorous, sometimes small, with a filiform stem 1 in. 

 long, sometimes larger and firmer, up to 3 in. high. Stem 

 always remarkably cartilaginous, very tough, polished, 

 glabrous, coloured like the pileus, even or slightly striate. 

 Pileus membranaceous, tough, conical then expanded, often 

 deformed in large specimens, centre becoming depressed, 

 J— 1^ in. across, not striate, glabrous, sooty or browni>h 

 fawn-colour when moist, dingy ochraceous when dry, shining 

 in both stages. Gills variable accoiding to the state of 

 expansion of the pileus, typically adnexed, or breaking away 

 and becoming free, size very variable, but clearly distin- 

 guished from allies by its toughness, polished appearance, 

 and whiteness of the gills. (Fries.) 



Var. versiformis, Fries, Icon., p. 114. 



Pileus convex then depressed or even infundibuliform, but 

 persistently papillate, densely but slightly striate, silkily 

 shining when drj*.
