CLITOCYBE 



Cap mostly depressed in center or infundibuliform, the margin 

 involute to near maturity. Gills narrowed toward the stem, typically 

 decurrent, but often onlj- slightly so and rarely they are even a little 

 notched at the stem. Stem fibrous externally, more or less elastic, not 

 brittle, sometimes hollow, continuous with the flesh of the cap. Spores 

 typically white, but flesh color in C. cerussata and tinted pinkish- 

 lavender in C. cyathiformis, elliptic, pip-shaped or rarely subspher- 

 ical, smooth in all species here included, said to be minutely echinu- 

 late in C. pulcherrima, C. alhissima and C. maxima. Volva and 

 annulus wanting. Growing on the ground or among leaves or on 

 rotting wood. One species, not yet found here (C. nehuJaris), is the 

 host of a parasitic Volvaria {V. Loweiana. See Mycologia 8: 65. 

 1916) and another (C peltigerina) grows on the lichen Peltigera. 

 This i& not always an easy genus to determine as the gills are vari- 

 able, in some cases approaching Tricholoma, in others Collyhia or 

 Omphalia. A few of the species are poisonous, as C. ill nd ens and C. 

 morhifera, but these are not classed among the deadly mushrooms. 

 Clitocyhe sudorifica causes profuse perspiration.
