when of a considerable size, at length expanded, quite 
smooth, soiled with portions of dead grass, &c., adhering to 
it; flesh thick. i 
Stem 7-8 inches high, 1j inch thick in the centre, 25-3 — 
inches thick at the base, which is incrassated and bulbous, 
somewhat rooting, and retaining a quantity of earth round it, 
by means of its cottony mycelium, solid, stringy within, ex- 
ternally smooth, subcartilaginous. 
Gills moderately broad, attached and slightly rounded 
behind, falcate in front. The colour of the whole in a dry 
state is a dull umber; the stem and gills being darker. Un- 
fortunately, no notes were preserved of its condition when 
gathered. - 
This magnificent species has the habit of Ag. grammopo- 
dius, which, however, it exceeds in size. It belongs, with it, 
to the section Tricholomata Hygrophana of Fries’ Epicrisis. 
Like too many exotic species, it is necessarily imperfectly 
defined, but it is too remarkable to omit altogether.

Pileus 11-3 lines broad, convex, membranaceous, plicate, 
yellow, ferruginous, extremely minutely wrinkled when ary; so 
as to appear pulverulent. Stem 3-3 of an inch high, 4 of a 
line thick, cinereous-brown, compressed: twisted, shining, 
smooth with a glaucous tinge, which arises from extremely 
minute globules, visible only under a high magnifier; at- 
tached by a little downy bulb. Gills pallid, few, attenuated 
behind, nearly free, with broad veiny interstices. The exact 
form of the gills and the mode of attachment are scarcely de- 
terminable. 
This charming little species is allied very closely to
