CRYPTQGAMIA. FUNGI. Agaricus. 
Stem solid, hard, dirty yellowish brown, bent in various directions, four 
inches high, half an inch diameter: Bolton ; who in a letter to me re¬ 
marks, that it is slow of growth, and of much longer duration than any 
of the deliquescent species which had fallen under his observation. 
(Livid Agaric. E.) Ag. luridus. Bolt. On Gibbet Hill, and other places 
near Halifax. 
IV. HOLLOW AND DECURRENT. 
( 1 ) Gills white. 
*Ag. niv'eus. (Schaeff.) Gills white, in pairs: pileus white, viscid, 
flattish: stem white, cylindrical. 
{Gfev* Scot. Crypt* 166. E.) Schceff. 232. not good. Description at Ind. 
p. 57. very exact. 
Gills decurrent, glossy white, few, in pairs. 
Pileus at first convex, afterwards flattened, and often depressed in the 
centre ; viscid, brittle, not fleshy. 
Stem hollow, white, one to two and a half inches high, thick as a goose 
quill. Major Velley. I am obliged to that gentleman for the knowledge 
of this plant being indigenous, for most of the preceding characters, and 
for the following observations:—The pileus is so little fleshy, that when 
dry, it is sufficiently transparent to exhibit the form of the gills. The 
decurrence of the longer gills, which is invariable, separates it from the 
Ag. coriaceus of Lightfoot, (Ag. orcades,) the gills of which, as he 
observes, do not touch the stem. It is much less fleshy than Ag. 
ehurneus. 
(Snow-white Agaric. Ag. virgineus. Fries. Grev. ? Dr. Greville 
describes his plant as abundant on lawns and pastures in autumn, and 
the stem as sometimes solid; under which circumstances it may not be 
easily distinguished from Ag. ehurneus of With. EA In a small clump 
of firs, near the middle of Claverton Down, Bath.r 
Ag. cespitc/sus. Gills watery white, few, broad: pileus very light 
brown: convex : stem white. 
Bolt. 41. C. 
Gills slightly decurrent, watery white, two or four in a set, few, broad. 
Pileus light brown with a yellowish tinge, convex, flat, and sometimes 
turning up with age; half to one and a half inch over; extremely thin, 
and with the appearance of streaks from the gills being seen through it. 
Stem hollow, white, from a quarter to one and a quarter inch high, thick as 
a crow quill. 
Whole plant semi-transparent. 
(Semi-transparent Turf Agaric. E.) Ag. cespitosus. Bolt. In Pack- 
ington park, Warwickshire. 
( 2 ) Gills red. 
Ag. farina'ceus, (Huds.) Gills dilute pink, edges scolloped, four in 
a set: pileus pinky brown, bossed: stem very pale pinky brown, 
thick at the top.
