422 FUNGUS-FLORA. 



On stumps. 



Readily distinguished by the densely tufted habit, and 

 growing on wood. The distinctly cartilaginous stem suggests 

 the genus Omphalia, but the gills are not truly decurrent. 



Clitocybe cryptarum. Letell. 



Densely caespitose. Pi lens somewhat conical, depressedly 

 floccose, spotted with brown ; gills rather decurrent, narrow, 

 arcuate, white ; stem white, rather striate, virgate, attenuated 

 upwards, more or less compressed, narrowly fistulose. 



Agaricus cryptarum, Letellier, Champ., p. 92, f. 88 ; Cke., 

 Hdbk., p. 52. 



On sawdust. 



Habit that of C. tumulosa. Pileus varying much in size, 

 according to the dimensions of the clusters. Inodorous, 

 insipid ; stem mottled within. (Berk. & Broome.) 



A doubtful species, respecting which little is known ; 

 Berkeley and Broome consider that they met with the species 

 intended by Letellier. Fries, on the other hand, considers 

 that it may be a form of Collybia fusipes. 



Clitocybe opaca. Fr. 



White. Pileus l|-2i in. across, flesh thickish at the disc, 

 "very thin elsewhere, convex, then expanded, umbonate, often 

 depressed round the nmbo, wavy, even, opaque, minutely 

 flocculose ; gills adnate with a suggestion of being decurrent, 

 closely crowded, about \\ line broad, white; stem l|-2 in. 

 long, 2-3 lines thick, unequal, somewhat fibrillose, wavy, 

 stuffed. 



Agaricus (Clitocybe) opacus, Fries, Hym. Eur., p. 93 ; Cke., 

 Hdbk., p. 52; Cke., Illustr., pi. 176. 



In woods. 



Solitary ior caespitose and grown together at the base. 

 Closely allied to C. cerrusata, with which it was once joined, 

 and differing mainly in the umbonate pilous. 



Clitocybe occulta. Cooke. 



Pileus l|-2i in. across, flesh rather thick at the disc, thin 

 elsewhere, white ; convex then plane and depressed, even, 

 smooth, but innately streaked or virgate, viscid, pallid, 

 smoky about the disc, whitish at the margin ; gills adnate 

 and very slightly decurrent, scarcely emarginate, white,
