232 FUNGUS-FLORA. 



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, i'orming a zone round the 

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

 then hemispherical, 4—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 j)l'^ne, crowded, pallid. At 

 once distinguished from all preceding species by the floccose, 

 not membranaceous ring. (Fries.) 



ACETABULARIA. (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. 



Acetahularia^ Berk., Linn. Journ., xviii., p. 389 ; Cke., 

 Hdbk., p. 139. 



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



Analogous with the genus Amanitopsis amongst the Leuco- 

 gporae. 



The present genus Avas founded — as a subgenus — by 

 Berkeley for the reception of brown or ochraceous spored 

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

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

 spored sj^ecies having a universal veil that remains at the 

 base of the stem as a volva, differs from Acetabularia in 

 having a secondary veil and adnate gills, nevertheless 

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

 and placing the species in LocelUna. 



Acetabularia acetabulosa. Berk. 



Pileus about 1 in. across, convex, tan -col our, margin 

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

 coming close up to the stem, distant, Ih line broad, pale 

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

 base surrounded by a small, whitish volva.
