Hygrophorus westii Murr. 



Uoydia 5: L39. L942 



Pileus 2.5 1 cm broad, convex, expanding convex, slight!) umbili- 

 cate, slimy-viscid, glabrous, pallid with a yellowish tint, disc slightl) 

 darker, margin involute, even. Context white, thin; odor somewhat 

 disagreeable, taste mild. 



Lamellae adnexed, arcuate, white, close, narrow, tapering behind. 



Stipe 2-3 cm • 5—10 mm, white, slimy-viscid, apex white-floccose, 

 enlarged above or below. 



Spores (5.5)6-8 x 3. .5 — 1 /<, ellipsoid to subpyriform, smooth, non- 

 amyloid. Basidia 40-48 ■ 5-9 p, 4-spored. Pleurocystidia and cheilo- 

 cystidia none, Gill trama composed of parallel to subparallel hyphae. 

 Cuticle an ixotrichodermium, 250-400/1 thick, the hyphae more or less 

 erect, densely tangled, 2-4 p broad. No hypodermium differentiated. 

 A few lactifers present. Clamp connections on the cuticular hyphae, 

 and occasionally on the lactifers. 



Habit, Habitat, and Distribution — On soil under oaks. Florida. 

 January. 



Material Studied — FLORIDA: West, F19307 (type, from near 

 Hogtown Creek, Gainesville, Jan. 11, 1940). 



Observations — The description of microscopic characters given 

 above is based on our study of the type. 



In appearance, the dried carpophores resemble those of 11. dis- 

 coideus (which has divergent gill trama), and Murrill erroneously 

 regarded it as a member of the section Hygrophorus (Limacium I. The 

 pilei of the type (dried) are "ochraceous tawny" to "buckthorn 

 brown," and the lamellae "cinnamon."
