Collybia stipitaria Fr. 



Stem Collybia. 



(Hym. Eur. p. 116. Syl. vol. v. p. 216.) 



Pileus thin, submembranous, campanulate convex or nearly plane, 

 umbilicate, sometimes with a minute blackisti papilla in the umbilicus, 

 fibrillose-hairy or squamulose, grayish, grayish-tawny, tawny or brownish; 

 lamellae adnexed, sometimes separating and becoming free, subdistant, 

 white; stem slender, tough, stuffed or hollow, fibrillose-hairy, bro'wn, the 

 fibrillose coating gray or tawny; spores elliptical, .00024 to .0003 inch 

 long, .00016 broad, with an oblique apiculus at one end. 



Pileus 3 to 6 lines broad; stem i to 3 inches long, one-third to one-half 

 a line thick. 



Dead stems twigs and leaves. Common June to October. 



This is another anomalous species. It revives under the influence of 

 moisture as in the genus Marasmius, and the stem is inserted at the base 

 as in some species of that genus, not radicating as in typical species of 

 Collybia. The adornments of the pileus are also peculiar. The fibrils 

 or hairs are generally collected in tufts or prostrate fascicles which give a 

 squamulose ai)pearance to the pileus. In dry specimens the disk is often 

 circumscribed by a narrow concentric furrow, and frequently there are 

 two or three of these furrows one beyond the other as indicated by 

 Cooke's enlarged figure of the species, and by the figure of A. scabellus 

 by Albertini and Schweinitz. 



Var. setipes Pk. has the stem 2 to 3 inches long and very slender, and 

 the tufted fibrils of the pileus commonly arranged in radiating rows. 

 These tufts extend beyond the margin and give it a beautiful somewhat 

 fimbriate appearance. This variety is common in the Adirondack region. 



Collybia zonata Pk. 



Zoned Collybia. 

 (Rep. 24, p. 61. Syl. vol. v. p. 216.) 



Pileus fleshy, thin, convex or nearly plane, umbilicate, fibrillose-tomen- 

 tose, tawny or ochraceous-tawny, sometimes marked with faintly darker 

 zones ; lamellae narrow, close, free, white or whitish, with a white pulver- 

 ulent edge; stem firm, equal, hollow, fibrillose-tomentose, tawny or brown- 

 ish-tawny; spores broadly elliptical, .0002 inch long, .00016 broad. 



Plant commonly cgespitose; pileus 6 to 12 hues broad; stem i to 2 

 inches long, about i line thick. 



Decaying wood. Albany county. August.
