Agaricus (Omplialia) griseo-pallida, Desmazieres, Crypt., 

 no. 120 ; Cke., Hdbk., p. 97 ; Cke., lUustr., pi. 241b. 



On naked ground. 



Somewhat resembles 0. umhellifera and 0. rustica. but dis- 

 tinguished from both by the pileus not being striate when 

 moist. 



Omphalia stellata. Fr. 



White. Pileus up to J in. across, truly membranaceous, 

 convex, umbilicate, pelluoidly striate, glabrous; gills de- 

 current, rather distant, distinct, thin, not triangular ; stem 

 usually less than 1 in. long, very slender, fragile, stuffed then 

 hollow, often curved, base dilated and radiately stiigose or 

 hairy ; spores elliptical, 6-7 X 4 /i. 



Agaricus (Omphalia) stellatus, I'ries, Syst. Myc, i. p. 163 ; 

 Cke., Hdbk., p. 97 ; Cke., lUustr., p. 241c. 



On rotten trunks, wood, &c. 



Gregarious: Allied to 0. integrella, but distinguished by 

 the broader gills. Distinguished from Omphalia umhellifera 

 by being more slender, pileus generally excentric, and 

 general form. 



II. MYCENAEII. 



* Campanellae. 



Omphalia campanella. BatscL.

 convex, sometimes becoming expanded, umbilicate, striate, 

 hygrophanous, rusty-yellow, gills decurrent, rather crowded, 

 connected by veins, yellowish ; stem about 1^ in. long, not a

Agaricus campanella, Batsch, Fr., Syst. Myc, i. p. 166; 

 Cke., lUustr., pi. 273, f. 1 ; Cke., Hdbk., p. 98. 



In fir woods, often on fir trunks. 



Stem horny, rigid, iistulose, 1-2 in. long, scarcely a line 

 thick, glabrous, bay; base attenuated and rooting, tawny, 

 strigose. Pileus membranaceous, tough, campanuiate, soon 

 convex; umbilicate, about |- in. across, yellow-ferruginous,
