Pastures and grassy places. Aug.— Nov. Not uncommon, but scarce 

 in some seasons. In the two last years I have not met with a single 



specimen " Pileus 1—2 inches broad, at length spreading towards the 



margin, but leaving the centre more or less convex as if umbonate 

 glabrous, margin often cracked, frequently contracted or lobed, bufhsh 

 reddish or brownish ; fesh whitish, thick in the centre, thin at the 

 margin. GUIs thick, distant, decurrent, connected by veins, separable 

 from the flesh of the pileus. Slem 1—2 inches high, 3—8 lines thick, 

 whitish, attenuated towards the base." Grev. I. c. A. ericeiis, With, is 

 a white variety with buff gills ; but with an incorrect synonym from 

 Bulliard. 



95. A.virgbmis, Wulf. (ivhite Field Agaric) ; white, pileus 

 thin moist convex then umbilicated, gills decurrent distant 

 connected by veins, stem slender stuffed attenuated downwards.

Pastures. Sept Nov. Extremely common. — Pileus 1 inch or 



more broad, slightly viscid when moist and shining as if oiled, with a 

 satiny lustre when dry, white, sometimes with a tinge of yellow or pink ; 

 various in shape, sometimes umbonate, often quite plane or depressed, 

 frequently obconic, margin more or less thin and transparent. GilU 

 broad, distant, with very prominent connecting veins, adnato-decurrent, 

 sometimes forked above. Stem 2 inches long, 1 — 2 lines thick, under 

 a lens fibrillose and sometimes pjilverulento-squamulose at the apex, 

 stuffed, the centre com[)osed of crisped fibres, at length more or less 

 hollow, with frequently a core running down from the {)ileus ; white, 

 with sometimes a tinge of pink at the base. Tdste like that of A. arca- 

 des This and the last are both eatal)le. There is no glandular ap- 

 pearance at the top of the stem as in A.cburncus ; with which when 

 once understood, the present species cannot be confounded. 



C. Hygrocybi; (from -jyoo; moist and xjp/; a head.) PiUus 

 thiUy viscid when moist. Stem hollow, 



96. A. psittacinus, Sclueff. (pnrrof/uet Agaric); green 

 changing to yellow viscid, pileus euinpanulate spreading striate 

 when moist, gills adnate ratiier distant, stem equal even.
