206 FUNGUS-FLORA. 



pellucid, margin striate, ratter umbonate, yellow becoming 

 pale; gills attenuated behind, adnexed, about 1J line broad, 

 rather distant, yellowish then pale cinnamon ; stem 23 in. 

 long, 1J line thick, attenuated upwards, straight, naked, 

 yellow, hollow ; spores ferruginous, elliptical, 7 x 3-5 /*. 



Bolbitius fragilis, Fries, Epicr., p. 254 ; Cke., Hdbk., p. 235 ; 

 Cke., Illustr., pi. 720A. 



On dung and amongst grass. Solitary, [or 2-3 clustered 

 togethered. 



More slender than Bolbitius Boltoni, fragile, drying up, 

 yellow becoming pale. Spores ferruginous. (Fries.) 



Bolbitius apicalis. W. G. Sm. (figs. 18, 19, p. 3.) 



Pileus conical, not expanding, | 1 in. long, meinbranaceous, 

 brownish, striate from the first up to the ochraceous, even, 

 subumbonate disc, the difference in colour between the two 

 parts defined by a distinct line ; gills free, at first pressed to 

 the stem, 11 line broad, ventricose, bright brown; stem 

 about 1^ in. long, incrassated at the base, striate, white, 

 minutely mealy under a lens, hollow ; spores brown, ellip- 

 tical, 9 x 6-7 p. 



Bolbitius apicalis, W. G. Smith, in Cooke's Hdbk., ed. i., p. 

 171 ; Cke., Hdbk., p. 235 ; Cke., Illustr., pi. 720s. 



In pastures. 



Distinguished by the pileus being striate and brown up to 

 the smooth, ochraceous disc. 



Bolbitius titubans. Fr. 



Pileus f-1 in. across, membranaceous, ovato-campanulate 

 then expanded, discoid, yellow ; gills slightly adnexed, 

 about 1 line broad, rather distant, pallid then salmon-colour ; 

 stem lj-2| in. long, about 1 line thick, straight, yellowish, 

 shining, hollow; spores 12 x 8 fi. 



Bolbitius titubans, Fries, Epicr., p. 254; Cke., Hdbk., 

 p. 235 ; Cke., Illustr., pi. 690. 



Amongst <rrass, &c. Very fragile, almost tottering. Fries 

 states that the gills are pallid then becoming purplish or 

 brownish flesh-colour, and in that respect his specimens 

 differed from the figures of other fungologists. He also says 

 that the spores appear purplish-brown.
