[our. Bot & Kew Misc. 1: ( is. L849 



Pileus 1 2—1 S nun broad, convex, at length plane, pale reddish 

 yellow, darker in the center. \er\ mucilaginous, margin striate. 



Lamellae subdecurrent. flesh-colored, unequal, medium broad, 

 distant, flesh) . 



Stipe 2.5-5 Cm long, 2 nun or more thick, pale \ellow or canieons. 



composed of longitudinal fibers, brittle, subpellucid, fistulose. 



Spores 5-7x3-4.5 u. ellipsoid, smooth. Yellowish in Melzer's 



reagent. Basidia 40-52 x 5-6 /j. 4-spored. Pleurocystidia and cheilo- 



cystidia none, (all trama subparallel. Subhvineniuin indistinct. Cuticle 

 of the pileus fibrillose, the surface hyphae gelatinous. Clamp connec- 

 tions not found. 



Habit. Habitat, and Distribution" — On low ground, South 

 Carolina. 



Material Studied — south Carolina: The type, borrowed and 

 studied through the courtesv of Kew Gardens. 



Observations — The microscopic characters given above are based 

 on our study of the tvpe. 



The cuticular hyphae of the stipe are non-gelatinous, and the stipe 

 is therefore not viscid. The species is near H. subminiatus, the spores ot 

 which are larger and of different shape. It differs from H. subceraceus 

 in its broader spores; from H. nitidus in its subdecurrent, flesh-colored 

 lamellae, its dry stipe, and its smaller spores; and from //. parvulus in 

 its pileus colors, its subdecurrent lamellae, its much larger basidia, 

 and slightlv smaller spores.
