RUSSULA REDIVIVA.

“ Easily distinguished from R. integra by the white gills.” — 
Stevenson. 
It is sometimes suggested that the three species called respec- 
tively R. Queletii (Fries), R. expallens (Gillet), and R. drimeia 
(Cooke) are but forms of one species, but with this we are not 
disposed to agree. There is a superficial resemblance in form, size, 
and colour, but there the resemblance ends. R. Queletii has white 
weeping gills, but those of R. expallens are pale yellowish, and 
those of R. drimeia sulphur-coloured from the first, besides other 
differences which become evident on comparison. Of the three 
Russula Queletii and R. expallens are most nearly allied, but the 
other does not belong to the same section. — M. C. C.

Pileus fleshy, firm, somewhat depressed, viscid, bright purple, 
centre dark purple (6-8 c.m. diam.), at length, except the disc, 
discoloured, cuticle separable, flesh purple, stem cylindrical, firm, 
equal, or a little incrassated about the base, 5-8 c.m. long, 2 c.m. 
thick, becoming purplish, mealy ; gills pallid yellow, furcate at the 
base, broad. 
Under trees. 
Obs. Gillet thinks that R. drimeia (Cke.) is the same species, 
which can hardly be the case, as that does not become discoloured, 
the flesh is not purple, and the gills are lemon-coloured from the 
first. Perhaps Russula Jragilis , Krombh., t. 64, fig. 14-18, may 
be this present species. — M. C. C.
