COLLYBIA. 13^ 



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

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

 long, very slender, flexuons, pallid, delicately coated with 

 white mealy down, ending in an elongated librillose, twisted 

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



Agaricus (CoUyhia) cirrJiatus^ 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 knoT^Ti by the gills being adnate 

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

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



Collybia tuberosa. Bull. 



Pileus up to h 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 i-li" ^^- loi^g? 

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

 rarely tinged rufous, base quite glabrous, springing from 

 a smooth, solid, yellowish or reddish sclerotium; spores

Agaricus {Collyhia) cin-hatus, Cke., Hdbk., p. 67 ; Cke., 

 Illustr., pi. 144b. 



Growing on decaying species of Bussida and other Agarics, 

 and on the ground among moss, &g. 



Small but tough, rather firm, gregarious, entirely white. - 

 C. cirrhata resembles the present species, but difi'ers 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.
