Murrill stales that this species suggests //. subprataisis. a Cuban 

 Species, but the gills are not sinuate and the pileus docs not lade. 



Murrill correctly interpreted //. subpratensis as a member of the se< - 

 tion Hygrophorus. The globose spores oi //. ntbluridus sharply sepa- 

 rate it from //. unguinosus Fr., as docs the drj stipe

Hygrophorus subceraceus I Murr. I Murr. 



Klisha Mitchell Sei. Soc. Jour. 55: 372. 1939 



Hydrocybe subceracea Murr., Klisha Mitchell Sei. Sue. [our. 55: 171. 

 1939. 



Pileus 1-3 cm broad, convex to subexpanded, at times w ith a small. 

 broad umbo, viscid, glabrous, hygrophanous, "buff yellow" to "apricot 

 yellow," flavous, tinged luteous when young and at the center when 

 mature, pale chrome yellow when faded, margin even to translucent- 

 striate when moist, entire to slightly lobed. Context very thin, flavous, 

 unchanging; odor none, taste mild. 



Lamellae short-decurrent to adnate, arcuate, broad or medium 

 broad, inserted, medium distant, pale yellow, unchanging, edges even. 



Stipe 2-4 cm long, 2-4 mm thick, concolorous with the pileus or 

 paler yellow, base at times slightly orange chrome, glabrous, not viscid, 

 subequal, flattened, hollow . 



Spores 5-7.5 x 2.5-3.5 /x, ellipsoid, smooth, pale yellow in Melzer's 

 reagent. Basidia 30-42 x 4.5-7 /*, mostly 4-spored, a few 2-spored. Pleu- 

 rocystidia and cheilocvstidia none. Gill trama subparallel. hvphae 

 4-8(10) fi broad. Cuticle of repent to more or less erect, somewhat ge- 

 latinous hvphae. No hypodermium differentiated. Pileus trama of ra- 

 dial hvphae. Clamp connections present on the cuticular lnphae. 



Habit, Habitat, and Distbibutiox — On soil, under hardwoods. 

 Florida, Michigan, and Oregon; also Quebec, Canada and the Nether- 

 lands, July-November. 



Material Studied — Florida: West & Murrill F1S374 (type, from 

 Newnan's Lake, Nov. 15, 1938). Michigan: Smith 58053. Oregon: 

 Gruber & Smith 20118. Canada: (Quebec) Bigelow 5512. Nether- 

 lands: Geesteranus 13478. 



Observations — The stipe of the type lacks a gelatinous layer, and 

 its surface is therefore dry. The dry stipe and narrower spores separate 

 this species from H. ceraceus Fr. In the Michigan collection (Smith 

 58058) the carpophores (dried) are somewhat brighter yellow than 

 those of the type; otherwise there is agreement. 



Notes on the type: Spores 5-7 X 2.5-3.5 ft, ellipsoid, smooth, pale 

 yellow in Melzer's reagent. Basidia 30-40 x 5.5-7 /*, 4-spored. Pleuro-
