CRYPTOGAMIA. FUNGI. Agaricus.

M. Bulliard tells us it grows on large trees, and on stumps of trees towards 
the end of autumn and in winter. Mr. Relhan found it at Babraham, 
near Cambridge, and communicated it to me. 
(Glandular Agaric. E.) Ag. glandulosus. Bull. 
*Ag. dimidia'tus. (Schaeffi) Gills whitish, branched: pileus red 
brown and grey, semi-circular, convex, scaly, fleshy, turned in at 
the edge: stem lateral, whitish. 
Sclueff. 233. 
Gills fixed, only branched near the edge of the pileus. 
Pileus greyish with reddish brown scales, one inch and a half by two inches 
and a half. 
Stem solid, inversely conical, fixed to the side of the pileus, full half an inch 
long, and about as much in diameter. 
This differs from Ag. ostreatus in being solitary, the pileus scaly, the gills 
not decurrent, branched towards the margin only, and not anastomosing at 
the base. It differs from Ag. betulinus in being fleshy, convex, the mar¬ 
gins inflected, and having a short stem. Mr. W oodward. 
(Semi-circular Scaly Agaric. E.) Ag. campestris. SchiefF. On an old 
ash at Ditchingham. Mr. Woodward. 
(2) Gills brown. 
Ag. concha'tus. (Bulliard.) Gills rich brown, extremely numerous 
and irregular : pileus brown, shining, glutinous, the edge greatly 
turned in. 
Bull. 298. 
Gills decurrent, rich brown, very numerous, of every varying length from 
seven inches to less than half an inch. 
Pileus brown, rather shining and glutinous, convex, or concave, edge rolled 
inwards and downwards, seven inches from the root to the outer edge, 
and nearly as much in breadth, but its various contractions make its 
shape very irregular. Flesh thick, brown, white. 
Stem solid, short, thick, brown.

Ag. aurantio-ferrugin'eus. Gills orange brown, not numerous, ir¬ 
regular: pileus orange brown, nearly circular: stem yellow 
brown, between central and lateral. 
Gills fixed, orange brown, thin, not very numerous, of three or four different 
lengths, not at all decurrent. 
Pileus orange brown, dry, scaly, and cracking; convex, nearly circular, 
from three to five inches over. Flesh yellow. 
Stem solid, more yellow than the pileus ; one inch and a half to three inches 
long, half an inch diameter, sometimes swelling out into a globular sub¬ 
stance near the gills; lateral in the large, but nearly central in some of 
the smaller specimens. 
Grows in clusters, is of a rich orange brown, and throws out a great quan¬ 
tity of seeds from its gills, of the same colour. It connects the Agarics 
with central stems with those which have lateral stems.
