Differs from the greenish species in the prior section (Furcates) in 
not being always green, but also verging on yellow. 
Between B. ceruginosa, Pers. Obs. 103, and Ag. virescens , 
Schseff., I discover no limit, nor between Secretan, 514, 516, 517.

Pileus green, without pellicle, innately flocculose, then rivulose, 
areolately squamose, easily distinguished from all others. Taste 
mild, edible. Stem solid, spongy within, firm, white. Pileus 
compactly fleshy, globose, then expanded, at length depressed, often 
unequal, always dry, not pelliculose, cuticle flocculose, splitting up 
into areolie or warts. Margin straight, obtuse, even. Size and 
colour variable, now deep, now pallid, and now green, becoming 
yellowish. Flesh white, less compact. Gills free, rather crowded, 
less yellowish in front than its allies, sometimes equal, sometimes 
furcate, mixed with a few shorter ones, white. — Fr. Mon. 191. 
Spores scarcely echinulate, 6 /x (W. G. S.), 8-10 x 8 /x (Britz.), 
6-7 /A (Bizz.), 6-7 /x or 8-9 x 8 /x (Sacc. ). 
Pileus 4 in. broad, convex, at length slightly depressed and 
irregular, of various livid hues, yellow, purple, and green, fleshy, 
rugulose, very slightly viscid, margin even. The edge of the 
pileus sometimes hangs down in a singular manner. The texture 
is altogether vesiculose, consisting of roundish cells. Gills white, 
forked, sometimes anastomosing at the base, rather close, moderately 
rigid, elastic. Spores round, white. Stem 1-2 in. high, \ an in. 
or more thick, obtuse at the base, various in form, slightly reticu- 
lated with raised lines. Taste and odour mild.— Eng. FI. v., 23. 
Pileus from two to four inches across, never viscid, fleshy, firm, 
at first globose, them umbilicate, expanded, much depressed in the 
centre in age, but the margin always remaining plane, obtuse ; the 
cuticle is shining, thin, transparent, splitting at the margin, pallid, 
or variously shaded with ochraceous tints, covered with a thicker 
stratum, which is opaque, ceraceous, farinose, broken up at length 
into irregular warts of a dull verdigris or glaucous hue. Gills pure 
white, perfectly free, but in age appearing slightly decurrent from 
the depression of the pileus, unequal, rather distant, forked par- 
ticularly at the junction with the stem, exceedingly crisp, firm, and 
brittle, varying greatly in breadth in different individuals, for the 
most part sublanceolate. Stem white, subrivulose, thick, nearly 
equal, hard, compact, not stuffed, but homogeneous, entirely com- 
posed of cells, softening in the centre with age. The flesh both of 
the stem and pileus is pure white. — Hussey. 
The following are the forms described by Secretan, and cited by 
Fries : — 
R. cogranulata. Sec. No. 514. 
“ Pileus in the centre bright orange, mixed with greyish, mealy, 
and dull. This tint is distributed at the sides in small labyrinthine 
compartments ; the intervals which separate the granular spots are
