CRYPTOGAMIA. FUNGI. Agaricus 
Ag. avella'neus. Gills white, numerous, irregular: pileus rich red¬ 
dish yellow, gently convex: stem brown yellow. 
Gills loose, white, with something of a yellowish cast; thin, numerous, 
three or four in a set, and often several long ones together. 
Pileus the colour of a fresh gathered ripe hazel nut; gently convex, rather 
bossed, thin at the edge, two and a half inches over. Flesh whitish, with 
a tinge of the nut colour. 
Stem solid, gently tapering upwards, brown, yellow, flecked with a scurf of 
a redder colour ; four inches high, near half an inch diameter. 
This species I believe was first found in England about three years ago, by 
Mr. Knapp, who then sent me an account of it, observing that it gave a 
greasy appearance to the paper in which he had preserved it. On making 
further inquiries concerning it, he favoured me with a drawing from his 
dried specimen, and the following observations. 
Gills white. Pileus nearly flat, of a nut colour, with an extremely fine 
woolliness. Stem tawny, rather scored, not hollow.-—I imagine it 
is a rare plant, as Mr. Knapp has not found it since, though its 
size and the length of its stem, as well as the elegance of its appearance, 
render it sufficiently observable. A single specimen was gathered in this 
neighbourhood, and brought to me this morning.

*Ag. geor'gii. (Linn.) Gills yellowish white: pileus yellow, convex,

Gills loose. Pileus brimstone coloured, four inches over. Stem solid, irre¬ 
gularly hollow with age. Linn. Clus. Haller. Pileus striated and hairy 
at the edge, white, changing to yellowish, and reddish yellow when old; 
but the gills do not lose their whiteness. Stem short, thick, woolly.

This species is introduced on the authority of Hudson and Relhan. I 
cannot collect the exact description of the gills from any of the authors 
who have mentioned it, bift from the general structure of the plant it is 
probable that they are loose. Ray Syn. p. 2. n. 2.

the plant nearly juiceless. E.)

Mr. Stackhouse had repeatedly'mentioned to me a large esculent Agaric 
found on the sea-coast in Cornwall, which is, I believe, a monstrous 
variety of this species. Its whole habit is very large, the button as big 
as a potatoe, the expanded pileus eighteen inches over, the stem as thick 
as a man’s wrist, the gills very pale ; the curtain as tough and as thick as 
a piece of leather, the juice yellowish; the flavour inferior to that of 
Ag. campestris. He has lately informed me that it corresponds with 
the description of J. B. Hist. iii. p. 824. cited by Linnseus under Ag. 
Georgii. t It was probably a plant of this kind, which was mentioned to 
f (So called from springing up plentifully about St. George’s day. Parkinson. E.)
