white. Surface dry sounding in the hand. It is at first hemis- 
pherical, the margin folded in, the summit a little depressed, then 
plane, the centre always sunk, and more or less deformed ; margin 
slightly depressed. Diam. 4^ in. Flesh white, firm, brittle, 4 lines 
thick. Gills white, having about the margin of the pileus a 
yellowish lustre at the edge ; they are numerous, slender, thick and 
veined at the base, 3^ lines wide, slightly arcuate, bifid, branched, 
and much veined at the part which reaches the stem ; short gills 
united entirely with their neighbours. Stem white, mealy, and 
with vein-like striae near the gills, with a faint tinge of yellowish, 
or olive, at the foot. 2£ in. long, 1 in. thick, swollen at the apex, 
conically attenuated and curved at the base. The foot is pointed.

Pileus the foundation is of a yellowish white, tessellated, laby- 
rinthed more or less finely, the little compartments charged with 
green spots, forming verdigris blotches, powdered. These are more 
marked in the centre, and their colour more pronounced in youth. 
They extend in a network more crowded at the margin, producing 
there a simple granulation. Finally the pileus becomes yellowish, 
with a deeper tint in the centre, a little shining, striate at the 
margin. The form hemispherical, centre a little depressed, then 
convex, and at length concave. Diam. 5 in. Flesh white, firm, 
4 lines thick. 
Gills, in infancy, with a faint tint of flesh-colour, then they 
become white, they are numerous, fragile in old age, 3 lines wide, 
their greatest width is about the margin of the pileus. Nearly all 
bifid on arriving at the stem. Short gills in a small number. 
Stem dull white, 2^-3 in. long, 1-1£ in. thick, solid, straight or 
curved, sometimes conic and attenuated at the foot, sometimes 
swollen with deformities (bumps), the tint is reddish at the base. 
Odour indifferent. 
Obs. It is difficult for me to admit with Persoon that this 
species is the same as Paulet, t. 95, f. 9, 10, 11. — Secretan.

var. A. Pileus in the first state the centre is verdigris 
powdery, the point in the middle darker, the green tint with a tinge 
of whiteness at the margin. Then the centre is mottled or yellow, 
turning to orange, the sides remaining of a verdigris green, more 
or less light. It is dry, dull, powdery, delicately like cloth, but 
without granulations. Later a darker tint, rather large, extends to 
the margin, the centre remaining of a light colour. In old age the 
surface is smooth, and the verdigris passes to yellowish green. It 
is some time plane, depressed in the centre, and finally the margin 
is elevated. Diam. 4^-5 in. Flesh white, not vinous under the
