291. Agaricus (Psalliota) exaltatus, n. s. ; pileo amplo sicco fusco-pur- 
purascente subsericeo ; stipite exaltato fusiformi radicato, medio cavo, 
fibrilloso eortieato pallido ; lamellis latis postice truncatis vel attenuato- 
rotundatis, e niveo fusco-purpureis. Hook, fil., No. 31, cum ie. 
Has. On clay and earthy banks. Darjeeling, 7,000 feet. May, 
June, Rare. 
Pileus 6 inches across, undulated, at length purple-brown, dry, 
obscurely silky ; flesh thin, except in the centre, loose, purplish-brown 
just beneath the cuticle. Stem 9 inches high without the rooting 
base, fusiform, 14 inch thick in the centre where it has a narrow 
cavity, covered with a thin, cracking, fibrillose coat. Veil, if present, 
fugacious. Gills varying greatly in breadth, truncate behind, or attenu- 
ated, but rounded, yentricose or broadest in front, not adnate, at first 
snow-white, at length mushroom-purple. Spores minute, purple- 
brown, obliquely elliptic. 
Fries suspected that Coprini would be found on a splendid scale 
in tropical countries. Later illustrations, whether of the pencil or 
herbarium, do not prove this, the species of Coprini being, gene- 
rally, either the same with our own, or obscure and uninteresting. 
The mushroom, on the contrary, assumes every conceivable luxuriance 
of form. The present is a noble species, and as singular in its 
characters as it is magnificent. 4. augustus is the only one of its 
allies that can compare with it in the development of the stem, The 
difference exhibited in the gills is remarkable; sometimes they are 
rounded behind, but attenuated and remote from the stem, as in 
A. cretaceus ; sometimes è of an inch broad, and abruptly truncate.

Of this I have seen no specimens, but the figure indicates a variety, 
differing in scarcely any character, except the purple, rather than
