RUSSULA REDIVIVA. 
71 
The stem, curved, ventricose, is attenuated at the base, it is pure 
white. 
Under firs. July, August. 
Obs. We distinguish this species from A. lividus (No. 521) 
especially by its colour in infancy, and by the purple tints of the 
centre, which do not exist in any other species. When it 
becomes greenish in old age care must be taken not to confound it 
with B. fur cat a, from which it is distinguished by the numerous 
gills and their flabbiness. — Seer. No. 520. 
The species above called A. lividus is most probably B. hetero- 
phylla. 
R. vaga. Seer. No. 523. 
var. A. Pileus approaching light purple, mixed with olive, dull, 
then deep purple red, the centre greenish olive. It is some time 
plane, finally a little concave, umbonate in the centre. Diam. 3 in. 
It is at length shining, a little viscid, margin striate and tubercu- 
lose. Flesh white, rather firm, 4 lines thick, conical, vinous under 
the cuticle, which is easily raised. 
Gills white, numerous, slender, fragile, straight, adnate, 3 lines 
broad, united by numerous anastomoses, and serpentine in old age. 
A few short gills. 
Stem covered in its length with a purple tint, swollen insensibly 
at the base, 2^ in. long, 7-8 lines thick, up to 1 in. Striate with 
fine whitish streaks. It becomes flabby, and yields to pressure. 
Odour agreeable and penetrating. — Seer. No. 523. 
var. B. Differs in its earlier stage, dull olive and convex ; it 
takes afterwards the same tints as the preceding. Finally it is dis- 
coloured entirely, and the margin is covered with striae. The gills 
remove from the stem, fairly passing as free. — Seer. No. 523. 
var. C. Pileus in infancy all green, centre darker, afterwards 
the deep olive centre admits in the middle a tint darker and shin- 
ing, the sides purple, becoming deep purple, the centre turns to 
green, mixed at last with yellowish. It approaches convex ; the 
middle, sometimes raised to a rather large boss, is depressed. The 
pileus becomes in time plane, and then concave, the margin striate 
and tuberculose at the extremity. Diam. 3 in. Flesh white, 3 
lines thick. 
Gills dirty white, veined at the base. 
Stem 7 lines thick, thickened and deformed at the base, soft, and 
then hollow. For all the rest the gills and stem resemble those of 
var. A. The odour is also the same. It is most delicate and 
fragile. — Seer. No. 523. 
var. D. It differs from the preceding in its smallness, its diam, 
not exceeding 2 in. It becomes in old age all black. — Seer. No. 
523.
