1 62 AGARICUS. 



Omphalia. grown pale above, pale rufescent below. Gills at first adnate, 

 nearly plane, then ascending and suddenly decurrent, rather 

 distant, white. 



Solitary or only subgregarious. There is no absolute depression, but only 

 a flattening of the centre of the pileus. 



On sticks, c. Rare. Aug.-Oct. 



Name Kd^nr<a, to bend or curve ; $v\\ov, a leaf. With bent gills ; elbow- 

 gilled. Berk. Eng. Fl. v. p. 62. Out. p. 133. C. Hbk. n. 224. Illust. PL

351. A. umbratilis Fr. Pileus 2.5 cent, (i in.) broad, shining 

 black-fuscous ; hoary when dry, somewhat membranaceous, obtusely 

 campanulate, then convex and umbilicate> smooth, margin some- 

 what striate. Stem 2.5-5 cent. (1-2 in.) long, 2 mm. (i lin.) thick, 

 tough, tubular but flocculoso-stuffed internally, equal, even, smooth, 

 fuscous - dead black. Gills adnato-decurrent, arcuate, crowded, 



broad, acute at both ends, becoming fuscous-white. 



Gregarious, tough, hygrophanous. In colours and external appearance it 

 approaches A. retostus, but is easily distinguished by the crowded gills and 

 other marks. It may rather be confounded with A. ambustus and A. atratus, 

 which however are removed from it by the characters of Collybia. It is larger 

 than those nearest to it and remarkably distinct. 



On the ground among grass. Coed Coch. Autumn. 



Spores 6-7 x 4-5 mk. B. Name umbratilis, remaining in shade. Perhaps 

 in reference to colour, as Fries compares it with A. ambustus, A. atratus, 

 and A. retostus. Fr. Monogr. i. /. 190. Hym. Eur. p. 164. Icon. t. 77. f.

352. A. griseus Fr. Pileus 12 mm. (}4 in.) broad, livid-grey 

 then hoary, hygrophanous, somewhat membranaceous, campanu- 

 late then convex, somewhat papillate and at length slightly um- 

 bilicate, not however expanded, smooth, striate. Stem 7.5 cent. 

 (3 in.) long, 2 mm. (i lin.) thick, slightly firm, cartilaginous, soon 

 fistulose, slightly thickened at the apex, round, tense and straight, 

 even, smooth, whitish-cinereous, longitudinally brittle, not rooting. 

 Gills shortly decurrent, distant, broad, rather thick, whitish-grey. 



Between Mycena and Omphalia. It has an analogy as regards stature with 

 A. campanella, and in both the pileus varies umbilicate or papillate. On 

 account of the gills, however, which are truly though slightly decurrent, it 

 must be referred to Omphalia. It is allied to Cautharellus replexus. 



In pine wood. Rare. Sept.
