COLLYI3IA. 1S3 



gills adnate, at length separated from the stem, crowded, 

 exceedingly narrow, very unequal, white ; stem 1-2 in. 

 long, very slender, flexuous, pallid, delicately coated with- 

 white mealy down, ending in an elongated fibrillose, twisted 

 root ; spores elliptical, 4-5 x 2-3 //,. 



Agaricus (Collybia) cirrhatus, Fries, Epicr., p. 89. 



Among moss, &c. 



Sclerotium not present in this species. Very variable in 

 size, but always small, tough, whitish, often becoming tinged 

 with rufous. (Fries.) 



Allied to C. conigena but known by the gills being adnate 

 at first. Differs from C. tuberosa in the rooting fibrillose 

 base of the stem, and the absence of a sclerotium. 



Collybia tuberosa. Bull. 



Pileus up to | in. across, flesh thin, convex then plane, 

 umbonate but not umbilicately depressed, minutely silky then 

 almost glabrous, even, opaque, white ; gills adnate, crowded, 

 thin, unequal, white, slightly ventricose; stem |-1| in. long, 

 thin, usually ascending, equal, obsoletely powdery, white, 

 rarely tinged rufous, base quite glabrous, springing from 

 a smooth, solid, yellowish or reddish sclerotium; spores 

 elliptical, 4-6 x 2-3 p.

 Illustr., pi. 1 44B. 



Growing on decaying species of JRussula and other Agarics, 

 and on the ground among moss, &c. 



Small but tough, rather firm, gregarious, entirely whito. 

 C. cirrhata resembles the present species, but differs in having 

 a downy rooting base to the stem, and in not springing from 

 a sclerotium. 



Collybia racemosa. Pers. 



Pileus 3-4 lines across, flesh very thin ; convex, papillate, 

 covered with grey down ; gills adnate, crowded, white ; stem 

 1-2 in. long, slender, bearing slender, minute stems with 

 abortive pilei, base black, sclerotioid, stuffed.
