So AGARICUS. 



Clitocybe. On sawdust. Coed Coch, 1878. July-Oct. 



Name ad, and grego, to gather into a flock. Clustered. Schceff. t. 305,

156. A. elixus Sow. Pileus 5-7.5 cent. (2-3 in.) broad, fulig- 

 inous when moist, then becoming pale with a somewhat silky 

 habit, fleshy at the disc, otherwise thin, convex then flattened or de- 

 pressed, umbonate, undulato-repand, becoming even but delicately 

 streaked; flesh dingy white. Stem 5 cent. (2 in.) long, about 12 

 mm. ()4 in.) thick, solid, firm, somewhat equal, even, fuliginous- 

 whitish, velvety at the apex. Gills everywhere truly but unequally 

 decurrent, distant, connected by veins, 4 mm. (2 lin.) broad, quater- 

 nate, pure white. 



Gills almost obconical-decurrent. The only one of this group which is not 

 caespitose. The habit is that of Hygrophorus caprinus, but it is certainly dis- 

 tinct in the gills being thin, and in no wise at length waxy-soft. 



In woods. Frequent. Oct. 



Very bibulous, flesh soft. M.J.B. Name elixus, soaked. From its 

 sodden appearance. Sow. t. 172. Fr. Monogr. \. p. 114. Hym. Eur. p. 91.

157. A. fumosus, Pers. Pileus 2.5-7.5 cent. (1-3 in.) broad, 

 becoming fuliginous-fuscous, soon livid, or grey when dry, truly 

 fleshy at the disc, thin towards the margin, convex then plane, 

 obtuse, or gibbous only when young, sometimes circinate and 

 regular, sometimes flexuous-undulated, even, smooth, somewhat 

 hygrophanous ; flesh hyaline when moist, whitish when dry. 

 Stem 5-7.5 cent. (2-3 in.) long, 4-12 mm. (2-6 lin.) thick, solid or 

 stuffed, fibrous-fleshy, somewhat equal, but often twisted or 

 curved, smooth, dingy white, more or less white-mealy at the apex. 

 Gills in regular specimens adnate, in irregular ones in one place 

 decurrent and in another rounded, crowded, distinct, at the very 

 first grey -white. 



Odour none. Gregarious, somewhat caespitose, tough, somewhat cartila- 

 ginous. The colour of the pileus varies more or less dark ; pellicle adnate. 

 Easily distinguished from A. elixus, c., by its obtuse pileus, which is often 

 regular, but never streaked. 



In woods. Uncommon. Oct. 



Spores 6 mk. W.G.S. The densely caespitose form was formerly regarded 

 as a variety, polius ; it is figured by Saunders & Smith t. 13. Fries has 

 separated A. polius as a distinct species ; it is figured in Icones t. 48. f. i. 

 Berkeley now regards what was formerly called var. polius as merely a cosspi- 

 tose state of A. fumosus. A. polius Fr. Icon. t. 48. f. i. is an entirely different 

 plant. Name fumus, smoke. From its smoky colour. Pers. Syn. 348.
