In pastures, &c. 



About the size of H. niveus, but very distinct in the thick 

 flesh at the disc of the persistently convex pileus, which is 

 not at all umbilicate, the thick, distant gills, and the strong 

 scent. The stem is stout and expanding upwards into the 

 pileus, both in Berkeley's type specimens and in his sketches, 

 nevertheless a thin-stemmed form, as described by B. & Br. 

 in the following note, may have occurred. 



Pileus about ^ in. in diameter, convex, fleshy, slightly 

 viscid, ivory-white. Stem f-1 in. high, not a line thick, 

 incrassated upwards, smooth, solid, pure Avhite. Gills thick, 

 broad, arched, decurrent, very few and distant, with a few 

 shorter ones intermixed. The whole plant exhales a strong 

 musky smell, like that of Eussian leather, or Potentilla 

 atrosanguinea, which it sometimes retains for years. It is at 

 once known by its delightful odour. (B. & Br.) 



Hygrophorus (Camar.) ventricosus. B. & Br. 



Pileus 2-3 in. across, very fleshy at the disc, margin thin ; 

 persistently convex, sometimes irregular, white ; gills deeply 

 decurrent, narrow, white ; stem 2-3 in. high, ^| in. at the 

 thickest j)art, ventricose, solid, smooth, white ; spores ellip- 

 tical, 7 X 4 /x.

Among grass. 



Stem often becoming imperfectly hollow ; gills sometimes 

 forked. Known among the entirely white species by the 

 very fleshy pileus, and stout ventricose stem. 



** Gills adnate or sinuate. 



Hygrophorus (Camar.) fornicatus. Fr. 

 Pileus 1-2 in. across, flesh thin, campanulate then ex-

 glabrous, white, or livid; gills sometimes almost free, at
