NATURAL HISTORY SURVEY 39 



Stem stuffed, soft, equal, fibrillose-striate, otherwise smooth, 

 naked or obsoletely pruinose at the apex, whitish, shortly and 

 bluntly rooted at the base. 



Spores 19 x 13 /A. Pileus 7 to 10 cm. broad; stem 8 to 10 

 cm. long, 1.5 cm. or more thick. 



On and about the base of stumps; not rare. The plants are 

 slightly glutinous when moist. A specimen found in woods at 

 Lombard, June, 1900, had the pileus 16 cm. broad, stem 3 cm. 

 thick, and lamellae 18 mm. broad. The spores are very broadly 

 elliptical, 7.5 to 10 //.., much smaller than the measurements given 

 by \Yorthington G. Smith, from the European plant. 



Collybia maculata A. & S. 



Pileus fleshy, firm, convex or nearly plane, even, glabrous, 

 white or whitish, sometimes variegated with reddish spots or 

 stains; flesh white. 



Lamellae narrow, crowded, adnexed, sometimes nearly or 

 quite free, white or whitish. 



Stem generally stout, firm, equal or slightly swollen in the 

 middle, striate, white. 



Spores subglobose, 4 to 6 /x.; pileus 5 to 10 cm. broad; stem 

 5 to 10 cm. long, 6 to 12 mm. thick. 



Moist woods. Millers, Indiana, June. Stem occasionally 15 

 cm. long. Our plants show sordid (not reddish) stains in drying. 

 In the fresh specimens no stains were noticed. 



Collybia velutipes Curt. 



Pileus fleshy, rather thin, convex or nearly plane, obtuse, 

 glabrous, viscid, reddish-yellow or tawny, the thin margin often 

 wavy and irregular. 



Lamellae broad, subdistant, rounded behind, slightly adnexed, 

 whitish or yellowish. 



Stem firm, externally cartilaginous, stuffed or hollow, brown 

 or tawny-brown, densely velvety-hairy. 



Spores narrowly elliptical or oblong-elliptical, 7.5 to 9 x 4 //,. 

 Pileus 2.5 to 7 cm. broad; stem 2.5 to 9 cm. long, 2 to 8 mm. 

 thick. 



On and about decaying trunks and stumps. Often densely 

 cespitose. A clump collected by Will McDonald, in a lumber 

 yard at Wheaton, in November, 1899, contained over a hundred 

 pilei. The lamellae are pal id or cream-color, becoming yellowish 

 with age. Substance of the stem wholly fibrous, and, with the 

 flesh of the pileus pure white within. 



A specimen found on a stump of Salix, near Wheaton, had a 

 fusiform radicating prolongation of the stem, extending into the 

 ground 5 cm. The species is capable of withstanding low tem- 

 peratures, and is often collected in November and December, 

 when snow is on the ground. It is edible. 



Collybia confluens Pers. 



Pileus thin, tough, flaccid, convex then nearly plane, obtuse,
