422 FUNGUS-FLORA. 



On stumps. 



Readilj distinguislied Ly tlie 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. 



Densel}^ caespitose. Pilous somewhat conical, depressedly 

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

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

 upwards, more or less comjiressed, narrowly fistulo>e. 



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

 Hdbk., p. 52. 



On sawduftt. 



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

 according to the dimensions of the clusters. Inodorous, 

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



A doubtful si^ecies, 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 Colhjhia fusipes. 



Clitocybe opaca. Fr. 



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

 ^ery thin elsewhere, convex, then expanded, umbonate, often 

 depressed round the umbo, wav}^ even, opaque, minutely 

 flocculose ; gills adnate with a suggestion of being decurrent, 

 closely crowded, about l^^ line broad, white; stem lJ-2-^7 in. 

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

 stuffed. 



Agaricus (Clitocyhe) opacus, Fries, Hym. Fur., p. 93 ; Cke., 

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



In woods. 



Solitary or caespitose and grown together at the base. 

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

 and differing mainly in the umbonate pileus. 



Clitocybe occulta. Cooke. 

 Pileus lh-2h 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.
