118 FUNGUS-FLOKA. 



Mycena pelianthina. Bolton. 



Pileus about 1 in. across, flesh, rather thick at the disc, 

 thin elsewhere; convex then expanded, obtuse, moist, hygro- 

 phanous, margin striate, pale livid-purple, becoming pale- 

 when dry ; gills adnexed, broad, distinctly connected by 

 veins, purplish, with a darker, fimbriated edge ; stem 2-3 in, 

 long 1| line thick, equal, firm, fibriUosely-striate above, 

 pallid, base more or less downy, hollow; spores elliptical, 

 7 X 4/x. 



Agaricus (Mycena) pelianthinus, Fries, Syst. Myc, p. 112; 

 Cke., Hdbk., p. 75 ; Cke., Illustr., pi. 156, f, 1. 



jigarieus denticulatus, Bolton, t. 4, f. 1. 



Among dead leaves in woods. 



Sometimes gregarious. Known by the purplish pileus ancB 

 gills. 



Pileus 1-2 in. broad, when dry whitish, tinged with 

 purple; stem 2-3 in. high, l|-2 lines thick; the gills ar& 

 sprinkled over with short purple hairs, arranged in fascicles 

 on the edge ; smell strong, (Berk.) 



;COLLYBIA. Tries. 



Pileus symmetrica], flesh usually thin, margin incurved! 

 at first, not coarsely striate nor corrugated ; gills free or 

 adnexed and rounded behind, membranaceous, soft ; stem 

 with a cartilaginous cortex, internally cartilaginous or soft, 

 fistulose, often rooting ; spores white, smooth. 



Collyhia, Pries, Epicr., p. 81 ; Cke., Hdbk., p. 62 (as a 

 subgenus of Agaricus). 



Growing on wood, leaves, and on decaying fungi, also on 

 the ground, and then often rooting. 



Most closely allied to Marasmius, which, however, difiers in 

 the dry, somewhat coriaceous, tough substance of the whole 

 fungus, somewhat persistent, und fully expanding when 

 moistened after being dried. Clitocyhe and Triclioloma differ 

 in the stem being fibrous externally, and Mycena in having 

 the margin of the pileus straight, and not incurved when 

 young.
