Var. 3. Gills few, pale green, whitish at the edges, four in a set, hut irre¬ 
gular : pileus green, changing to yellow brown, convex, bossed, irregular: 
stem green above, yellow below. 
Gills fixed, dilute green, pale yellowish brown, or whitish towards the 
edges, four in a set, but the smaller series very irregular, sometimes 
absent, sometimes two in a place; large ones about thirty. 
Pileus convex, bossed, irregular, border scored, turning up with age, green 
when young, changing to a varying mixture of brownish yellow and 
green, one to one and a quarter inch over. 
Stem hollow, cylindrical, splitting, greenish upwards, yellowish below, one 
and a half inch high, thick as a raven quill. 
The whole plant semi-transparent, and so slimy, that it is with difficulty 
retained between the fingers. 
Edgbaston park, by the stews; not frequent. 21st October, 1790. 
Var. 4. Gills loose, pinky, fleshy, four in a set; pileus pale pink: stem 
pinky. 
Gills loose, pinky, fleshy, brittle, not numerous, in contact with, but not 
fixed to the stem, four in a set. 
Pileus pale pink, conical, pointed, edge irregular and uneven, almost clasp¬ 
ing the stem when young, turning up with age and cracking entirely 
through to the very centre; height of the cone one inch. Flesh thin, 
pinky. 
Stem hollow, white with a pinky tinge, cylindrical, but flatted, often 
cracking through its whole length on one or both sides, and the edges at 
the cracks turning in so as to give the appearance of two stems united 
together; one to two inches high, quarter of an inch diameter. 
Pastures, Edgbaston, by the long stew in the park, on land sloping to the 
north-east. 14th October. 
Var. 5. Gills loose, yellow, two, three, or four in a set: pileus and stem 
pinky. 
The smallest gills are very minute, and frequently wanting. 
On the same sloping ground as the preceding. 22d July. 
Ag. aurantius is the strongest exception I have met with to the present 
mode of arranging the genus. The last two varieties undoubtedly 
belong to the aurantius , many of the plates of which will give a good 
idea of them, if the colours, and the circumstances of the gills were 
changed. Perhaps the gills in an earlier stage of growth may be found 
attached to the stem; and as to colour, this species is unusually sportive. 
To prevent embarrassment I shall introduce them as exceptions to the 
general distribution; and what system exists without its exceptions ? 
On further examination I am satisfied that the gills are all fixed to the 
stem, though in some of the varieties only by a slender thread-like sub¬ 
stance which breaks as the pileus expands. All these varieties turn 
black in decay. 
Ag. cera'ceus. (Wulfen.) Gills pale yellow, in pairs: pileus deep 
yellow, hemispherical, smooth: stem deep yellow, cylindrical. 
Sowerhy 20— Wulfen, in Jacq. Misc. 15. ii. 2. 
Ag. stipitatus; pileo hemispherico stipiteque subjistuloso flavis : lamellis aquose 
luteolis. Wulfen. 
Gills fixed, yellow, four in a set, not crowded, broad. 
Pileus convex, dry, deep yellow, three-fourths of an inch over, flat and 
turning up with age. 
Stem with a fine hollow, yellow, thick as a crow or raven quill, full one inch 
high, two tenths diameter. Flesh yellow.
