CoUybia radicata Relh. 

 Rooted Collybia 



(Hym. Eur. p. 109. Sylloge vol. v. p. 200.) 



Pileus fleshy but thin, convex or nearly plane, sometimes somewhat 

 umbonate, glabrous, viscid or even glutinous when moist, often radiately 

 wrinkled in the center, varying in color from grayish-brown to dark- 

 brown, sometimes almost white, flesh white; lamellae broad, subdistant, 

 adnexed; stem long, firm, glabrous, stuffed, slightly tapering upward, at 

 length striate or grooved, colored like or paler than the pileus, ending in 

 a long root-like extension which penetrates the earth deeply; spores 

 elliptical, with a slight oblique apiculus at one end, .0006 to .0007 inch 

 long, .0004 to .0005 broad. 



Pileus 2 to 3 inches broad; stem 4 to 8 inches long, 2 to 3 lines thick. 



In woods and bushy places, generally about stumps or under trees. 

 Common. June to September. 



Var. furfuracea Pk. Stem furfuraceous, less distinctly striate. 



Var. pusilla Pk. Plant small, pileus about one inch broad, stem 

 slender. 



The \z.x\t\.y furfuracea is common, and connects this species with C. 

 longipes which has a villose stem and a dry velvety pileus. This species 

 has not yet been found here. The variety is apparently peculiar to this 

 country. Ndsv^ly pusilla passes gradually into the typical form. In dry 

 weather the viscidity of the pileus is not noticeable ; in very wet or rainy 

 weather it may be so fully developed that it may drop like gluten from 

 the surface. The striations of the stem are more distinct in dried than 

 in fresh specimens. In wa,r\Q\.Y furfuracea they are sometimes scarcely 

 perceptible in the fresh plant. 



This species was classed as edible by Rev. M. A. Curtis. I have not 



tried its esculent qualities, but suspect its thin flesh may be somewhat 



tough. 



Collybia platyphylla Fr. 



Broad-gilled Collybia. 

 (Hym. Eur. p. no. Syl. vol. v. p. 203.) 

 Pileus fleshy but thin and fragile, convex becoming flattened, obtuse, 

 moist in wet weather, more or less streaked with fibrils, commonly grayish- 

 brown but varying from whitish to dark-brown, sometimes with the disk 

 darker than the margin ; lamella broad, adnexed, usually deeply emar- 

 ginate or obliquely truncately notched next the stem, white ; stem stout, 

 fleshy, equal, striate or fibrillose-striate. stufTed or hollow, white or
