AGARICUS. 



Clitopilus. Subgenus XIV. CLITOPILUS {kxItos = K\n{)s, a declivity ; 

 7r?\os, a cap). Fr. Epicr. p. 148. Rosy-spored. Stem fleshy or 



fibrous, diffused upwards into the pi- 

 leus, the margin of which is at first 

 involute. Hymenophore continuous 

 with the stem; gills equally attenuated 

 behind and somewhat decurrent, not 

 separating or sinuate. Growing on 

 the ground, often stroftg-sfnelling, pi- 

 leus more or less depressed or U7nbil- 

 icate, with a similarly coloured um- 

 bilicus. Fr. Hym. Eur. p. 197. 



Clitopilus corresponds with Clito- 

 cybe, and differs from Entoloma as 

 Clitocybe differs from Tricholoma. 



XV. Agaricus {Clitopilus) pruiui- 

 lus. One-third natural size. 



II. Sericelli (slightly silky). 



I. Orcelli (A, Orcella). Gills deeply decur- 

 rent. Pileus irregular, somewhat excentric, 

 Jlexuous, scarcely hygrophanous, margin at 

 first flocc u lose. 

 Pileus regular, silky or hygrophanous-silky, 



margin involute, naked. Gills adnate, slightly decurrent. 



I. — Orcelli. 



444. A. prunulus Scop.— Pileus 5-10 cent. (2-4 in.) broad, 

 white or more rarely becoming cinereous, truly fleshy, compact, 

 convex then flattened, and at length depressed and repand or 

 unequal, delicately pnmiate, hence the surface is unpolished and 

 dry; flesh thick, white, unchangeable. Stem 2.5 cent, (i in.) 

 and more long, about 12 mm. {yi in.) thick, solid, firm, somewhat 

 ventricose, naked, often striate, white, villous at the base. Gills 

 deeply decurrent, attenuated at both ends and chiefly behind, 

 sojnewhat distant, quite entire, white then flesh-colour. 



The pileus is always firm, never viscid, and not zoned or spotted. The gills 

 are less crowded than those of A. Orcella. Odour pleasant, of fiew meal. 

 There is a white variety {Quel. t. 5./. 3 and Orcella/. 2), which forms a 

 connecting link with A. Orcella. A. prunulus Viviani t. 3 represents A. 

 graveolens. 



In woods and open ground. Common. July-Oct. 



It has been reckoned among the most delicious of edible species, and it has 

 the advantage of appearing early in the season. It may also be dried and 

 preserved for future use. It is easily distinguished by the pure pink gills run- 

 ning a considerable way down the stem, and by its fragrant scent of fresh 

 meal. It never appears anywhere in profusion. Spores 10-16x6 n)k. K.; 

 12-14x4-6 mk. B.; 11x6 mk. W.G.S. ^dimQ^prunus, plum. Scop. Cam.
