RUSSULA REDIVIVA.

gills assuming a red tint, but this can hardly be considered more 
than a “ form.” 
Russula (Rigidae) olivacea ( Schceff.J. Fries Fpicr. 356. Fr. Hym.

Mild ; pileus fleshy, convex, then flattened and depressed, rather 
silky and squamulose ; margin spreading, even, flesh white , then 
somewhat yelloivish ; stem firm, ventricose, pale rose or pallid, 
internally spongy, stuffed; gills adnexed, broad, yellow , mixed 
with shorter and furcate ones. 
In mountain fir woods. Rare. 
Allied to K. rubra, but stem definitely spongy, pileus unpolished, 
gills soft and brightly coloured ; certainly distinct ; corresponding 
to K. aluta cea. Colour of the pileus from dingy purple to olive, or 
altogether tawny-olive. Spores yellow. — Hym. Eur. 445. 
Spores globose, 10 p (Quelet), 10 p (Sacc.). 
Fries in Hym. Eur. refers the following, from its habit, to the 
present species. 
Pileus approaching a mixture of olive, of green, and of dark 
brown, the injured places obtaining purple tints ; at other times 
the first tint is deep olive green, of one colour, dull, like cloth ; 
later, sometimes it remains olive, greyish at the margin, more deep 
at the centre, sometimes it turns a light purple at the margin, 
darker at the centre, sometimes it becomes all dark crimson. 
Finally the middle offers a yellowish mixture, which in old age is 
blanched ; the aspect is dull, as if mealy. The first form is convex, 
the summit flattened, the margin folded beneath, widens, becomes 
plane, and then a little concave ; diam. 6 in. Flesh white, taking 
at last yellowish tints, vinous under the cuticle. It is rather soft 
in the interior, but it is enclosed in a stem with a sort of firm bark, 
thick and hard when young. The thickness of the flesh of the 
pileus is 9 lines ; it enters into the gills. 
Gills for some time with a yellowish lustre, finally ochre-yellow, 
shining ; they are almost crowded, and appear numerous ; they 
prove remote in old age ; they follow the contour of the pileus, are 
adnate at the same level, and are easily bifid at that point, 6 lines 
wide, and preserve the same near the margin of the pileus, very 
fragile, soapy to the touch. 
Stem washed with a fine rose. This tint, which appears in youth 
near the gills, extends afterwards through the whole stem ; it is 
more pronounced on one side than the other (2J in. long, the thick- 
ness of a good thumb). Straight, or a little curved, swollen above 
in old age, sometimes a little ventricose about the base, ordinarily 
attenuated, and slightly curved at the foot, holding the odour of 
the fir. In dry seasons the pileus cracks into deep fragments, 
which show the white flesh. — Seer. 489.
