Bussula sanguinea, !E*ries, Epicr., p. 351 ; Cke., Hdbk., p. 

 322 ; Cke. Illnatr., pL 1019. 



Among grass in Troods. 



-S. nAra agrees with the present species in colonr, bnt 

 differs in the very hard, rigid, somewhat gmmoTis flec'h of 

 the pileus, and in the gills bec»ming yellowish. Known, 

 from aU other species hy the truly decurrent gUls. 



Russala fragilis. Pr. 



Acrid. Pilens 1—1 J in. across, flesh "very thin and very 

 fragile ; convex at first and often nmbonate, then plane and 

 depressed, pellicle thin, rather viscid in moist weather, 

 becoming pale, colour variable, often opaque, iypicallyrflesh- 

 colonr, becoming abnost or entirely white, often with reddish 

 spots ; margin very thin, tnbercnlosely striate ; gills slightly 

 adnexed, very thin, broad, crowded, ventricose, all eqnal, 

 pure w^hite; stem Iv— 2 in. long, slender, often slightly 

 striate, shining white, spongy within and soon hollow; 

 spores minutely echinnlate, 8-10 x 3 /t.

In woods, &c. 



Difficult to define from fragile forms of B. emetica, bnt the 

 gills are much more crowded, ventricose, thinner, and the 

 margin often eroded ; pileus thinner, more las ; flesh en- 

 tirely white — not red nnder the cuticle ; margin tubercnlose, 

 and the entire fungus smaller and more fragile.

 Size and habit of type form, but every part white from, 

 the earliest stage ; spores 8 /i diameter.

Pileus about 1^ in. across, expanded and depresseii, thin,

 sometimes spotted with yellow, green, or olive ; flesh soft, 

 white, peppery; stem about li in. long, 2—3 lines thick,
