232 FUNGtJS-FLOEA. 



On the ground among grass, moss, &c. 



Small, solitary or gregarious, stem obsoletely fistulose, 

 1-2 in. long, scarcely a line thick, equal, lax, even, glabrous, 

 yellowish, ring floccose in texture, forming a zone round the 

 stem, white. Fileus rather fleshy for its size, campanulate 

 then hemispherical, 4r-5 lines hroad, even, glabrous, not 

 moist. Colour normally ochraceous, but brownish cinnamon 

 in specimen figured (in Icones, pi. 105, f. 4) ; gills entirely 

 adnate, at first ascending then pLme, crowded, pallid. At 

 once distingiiished from all preceding species by the floccose, 

 not membranaceous ring. (Fries.) 



ACETABULAEIA. (Berk.) 



Pileus regular; gills free from the stem; stem central; 

 universal veil present, remaining as a volva at the base of 

 the stem; spores tawny or brown. 



Acetdbularia, Berk., Linn. Journ., xviii., p. 389 ; Cke., 

 Hdbk., p. 139. 



Locellina, Sacc, Syll., vol v., p. 761. 



Analogous with the genus Amanitopsis amongst the Leuco- 

 tporae. 



The present , genus was founded — as a subgenus — -by 

 Berkeley for the reception of brown or ochraceous spored 

 agarics furnished with a volva, and having free gills. The 

 genus Locellina, Gillett, founded for the reception of a rusty- 

 spored species having a universal veil that remains at the 

 base of the stem as a volva, diifers from Acetahularia in 

 having a secondary veil and adnate gills, nevertheless 

 Saccardo has made the mistake of sinking Berkuley's genus, 

 and placing the species in Locellina. 



Acetalbularia acetabulosa. Berk. 



Pileus about 1 in. across, convex, tan-colour, margin 

 plicate or deeply striate ; flesh very thin ; gills free, but 

 coming close up to the stem, distant, li- lino bioad, pale 

 brown; stem about 2 in. long, equal, white, hollow, the 

 base surrounded by a small, whitish volva.

 from Sowerby).
