expanded, indistinctly umbonate, often becoming depressed

 slight decurrent tooth, ventricose, 3-4 lines broad, thickish, 

 rather distant, whitish ; stem 2-3 in. long, 2-3 lines thick,

 p. 298; Cke., lUustr., pi. 919. 



Amongst grass. 



Hygrophorus unguinosus resembles the present species, but 

 is distinguished by the viscid pileus. M. Clarkii is readily 

 distinguished by the globose spores. 



Hygrophorus (Camar.) clivalis. Fr. 



Pileus about 1^ in. across, disc rather fleshy, remainder 

 very thin, fragile, at first campanulate, obtuse, margin in- 

 curved, flexuous, glabrous, even, opaque, then expanded and 

 gibbous, irregular, often cracked, polished, shining, striate 

 owing to the thinness of the margin ; gills at first adnexed, 

 crowded, very ventricose when the pileus is expanded, dis- 

 tant, rather thick, fragile; attenuated behind, or free, or 

 arcuate and with a decurrent tooth ; stem solid, flesh fibrous, 

 not more than 1 in. long, 3—4 lines thick, attenuated at the 

 base, round or compressed and curved, even, glabrous, fragile, 

 mostly white.

 free.
