Gills loose, in contact with but not united to the stem, moderately nume¬ 
rous, four in a set, brown grey changing to black and deliquescing. 
Pileus light brown, or like ivory, polished, smooth, wrinkled when old like 
wash-leather, bluntly conical, or rather the shape ©f the broader end of 
an egg, one and a half inch from the edge to the apex, and as much across 
at the base. Flesh thin, white. 
Stem hollow, white, smooth, cylindrical, pithy within, bulbous at the base, 
five inches high, thick as a goose quill. The hollow sometimes very fine, 
and without pith.

Bull. .58. 
Gills loose, grey, mottled, turning black, broad, mostly in pairs, numerous, 
deliquescent, shorter gills narrow in proportion to the long ones, and often 
not extending to the edge of the pileus. 
Pileus brownish white, smooth, satiny, exactly the shape and about the 
size of the broader half of a hen’s egg cut across its longer axis. 
Stem hollow, cylindrical, brownish white, two to three inches high, thick 
as a crow quill. 
Ag. papilionaceus. Bull. Edgbaston park. 7th Nov. 1790. 
Ag. plicat'ilis. (Curt.) Gills grey, in pairs; pileus ash-coloured, 
centre brown yellow: stem white. 
Curt. 200— Batsch 2—( Sowerby 364. E)— Battar. 27. B. C — (Not FI. Dan. 
832. 2.) 
Gills loose, not reaching to the stem, grey or purplish grey, changing to 
black, semi-transparent, deliquescing, not numerous, in pairs. 
Pileus grey with a tinge of yellow, centre brown, yellow, conical, flat when 
expanded, edge at first turned down, with age turning up, sides semi¬ 
transparent, plaited, centre with a small boss sunk in a hollow, half to one 
inch over, centre underneath white, fleshy. 
Stem hollow, white, smooth, cylindrical, feeble, two to three inches high, 
thick as a crow quill. 
Curtain very evanescent, its remains sometimes fringing the edge of the 
pileus. 
This has been confounded with Ag. momentaneus, but the gills being in 
pairs, and their approach to the stem limited by a fleshy circle in the 
centre of the pileus on the under side, are at all times sufficient to point 
out the difference.
