218 SECTIOX HYGROCYBE 



Lamellae adnexed, yellow or yellowish brown, narrow, ascending, 

 subdistant. 



Stipe about 2 cm long, 2 mm thick, colored like the pileus, equal, 

 viscid, hollow. 



Spores 7-9 X 4. .5-6 /a, ellipsoid, smooth, pale yellow in Melzer's 

 reagent. Basidia 31-44 X 6-8 jx, 4-spored. Pleurocystidia and cheilo- 

 cvstidia none. Gill trama subparallel to parallel, with scattered 

 lactifers. Cuticle of gelatinous, more or less repent hyphae, 2.-5-5 fi 

 broad. No hvpodermium. Pileus trama of radially disposed hvphae, 

 lactifers present, 3-4(5) p broad. Clamp connections present on the 

 cuticular hyphae. Surface hyphae of stipe gelatinous. 



Habit, Habitat, and Distribution — On soil among moss, in 

 swampy woods, Massachusetts and Florida, September and October. 



Material Studied — Florida: Murrill F18739. Massachusetts: 

 Morris (Peck's type, from Ellis, September). 



Observations — This species is distinct from H. conicus, which it 

 resembles in shape, more viscid pileus, bright-red stipe, and persistent, 

 unchanging color on drying; and from H. cuspidatus by its viscid stipe 

 and small spores. Although in the Florida collection the spores tend to 

 be slightly larger, and some basidia were 2-spored, it otherwise closely 

 resembles the type. 



The microscopic characters given above are based on our study of 

 the type. In the original description Peck (1907) gives the spores as 

 6-7.5 X 4-5 fi, but we found them larger.
