28 FUNGI. [Ar/aricus. 



The variety with yellow milk I have found at Barnby in the willows 

 near Newark and at King's Cliffe, Norths., where A. theiogalus abounds; 

 but the two are quite distinct. 



62. A. subdulcis, Bull, (subacrid rufous Agaric) ; subacrid, 

 pileus smooth polished dry rufescent, gills flesh-colour at length 

 ferruginous, milk white unchangeable, stem smooth at length 

 hollow. Bull t. 224. Pers. Syn. p. 433. Fr, Syst. Myc,

Woods. Sept. — Oct. Not so common as the last.— Pi/ez<5 1 — 4 inches 

 broad, dark chocolate, sometimes slightly viscid when young. Alilk 

 white, acrid when the plant is old. Gi/is at length deep red-brown, 

 scarcely at all forked. Stem 1 — 2 inches high, | — k an inch thick, 

 substance looser than in the last at length hollow. I once found a most 

 splendid variety of this at Colly weston. Norths., in which the pileus and 

 stem were of a bright orange, very like Bolt. t. 9, but the milk was not 

 yellow. 



63. A. theiogalus, Bull, (jjelloiv-milked Agaric) ; subacrid, 

 pileus dry smooth somewhat zoned, milk white changing to 

 yellow. Bull t. bQl.f. 2. Pers. Syn. p. 431. Fr, Syst. Myc.

Woods amongst dead leaves. July — Nov. Woolhope, Herefordshire. 

 Mr. Stackhuuse. King's Cliffe, Norths. Bev. M. J. Berkeley. — Pileus 

 1 — 3 inches broad, buff, sometimes slightly tinged with tawny, at first 

 hemispherical, dimpled, at length depressed, more or less zoned ; mar- 

 gin wavy, involute and minutely downy when young ; Jiesli firm, crisp. 

 Gills very slightly decurrent, connected by veins, distant, by no means 

 rigid, salmon-coloured, slightly forked, about as broad as the flesh of 

 the pileus. Milk white, rather acrid with a peculiar taste, changing 

 instantly on exposure to air to a delicate but beautiful yellow, as does 

 the whole plant when cut. Stem U inch high, ^—1 inch thick, at first 

 nearly white, obese, paler than the pileus, downy at the base, more or 

 less hollow. — A very elegant species, not to be confounded with the 

 variety of A. quietus mentioned above. A. zonariusy Bolt, is quoted by 

 Fries under A. deliciosus, but a comparison of the figure with the 

 description shows it I think to be certainly the present species. 



64. A. rufus, Scop, (rufous milky Agaric) ; extremely acrid, 

 pileus subobtuse dry polished or squamulose rufous, milk white, 

 stem subsolid. Scop. 451. Fr. Syst. Myc. v. I. p. 71. Klotzsch,

Plantations at Edgbaston in clayey soil. Withering. Fir plantation 

 between Poole and Bourne Mouth, on a sandy bank. Sept. — Pileus 3 

 inches broad, plano-convex, slightly or strongly umbonate, with a de- 

 pression round the umbo as the plant advances, deep rufescent, adpresso-
