120 FUNGI. [Agaricus. 



Common. — Gregarious, csespitose. Pileus 3^ inches or more high, 

 subcarnose, campaniilate, obtuse, the edge uneven, dirty-grey, at length 

 brownish, innato-fibrillose, more or less farfuraceous and corrugated, 

 the apex often scaly. Gills very broad and close, with numerous 

 pellucid processes, ventricose, umber, the mai'gin white, rounded behind, 

 quite free. Stem Q^ inches high, ^ an inch thick, fistulose, juic}', 

 fibrillose, attenuated upwards, brittle, the substance banded concentri- 

 cally. There is generally a prominent mark at the base, caused by the 

 pressure of the edge of the pileus in an early stage of growth, which 

 has somewhat the appearance of a volva.

Roots of trees, bottoms of posts, Sec. May — Nov. Very common. 

 — Csespitose. Pileus ^ — 1 inch or more broad, half-ovate, often more 

 or less irregular from the dense mode of growth, sprinkled with glitter- 

 ing meal, strongly striate, almost plicate, rufous, the umbo darkest, 

 the margin cinereous, very thin ; veil very fugacious. Gills attenuated 

 in front, broad behind, ascending, attached above, umber mottled with 

 the sporules, which appear black when viewed in a mass, but are really 

 brown-purple. Stem 2 — 3 inches or more high, 2 lines thick, hollow, 

 brittle, squamuloso-pulverulent, the epidermis often cracked into little 

 scales, very faintly tinged with red, attenuated upwards ; the base 

 downy and sometimes assuming the appearance of a volva, as in 

 A. atramentarius. A. acefabulosus. Sow. t. 303, is perhaps such a 

 form, if the strongly marked spicules do not indicate a distinct species. 



321. A. cinereus, Bull, {cinereous Agaric) ; pileus at first 

 cylindrical sulcate squamulose or tomentose cinereous, apex 

 bald even, gills linear, stem scaly subtomentose. Bull. t. 88.

Gardens, rich meadows, saw-dust, dung, &c. July — Oct. Very 

 common. — Pileus 2 inches high before expansion, then 3 inches, but 

 very variable in size, sulcate, at first cylindrical, rather flat at the apex, 

 clothed with fugacious adpressed or slightly recurved feathery scales ; 

 then conico-campanulate ; at length inverted with the margin spUt 

 and rolled back. Gills black, clothed with pellucid conic processes 

 and elliptic black sporules. Stem sometimes 5 inches high, \ — ^ of an 

 inch thick, clothed near the apex with thick patent down, near the 

 base with small adpressed scales, very fragile, hollow, without any 

 cottony fibres. 



322. A.macrorhizuSy Pers. (long -rooted Agaric) ; pileus ovato- 

 campanulate obtuse clothed with evanescent reflexed scales.
