Pileus 4-6.5 cm broad, campanulate-umbonate, remaining umbo- 

 nate or becoming plane to slightly depressed, orange-buff to pale in- 

 carnate yellowish to pale yellowish brown, disc more brightly colored 

 (reddish), surface slimy viscid, margin whitish and shimmering-fibril- 

 lose, occasionally creased, finally spreading, fleshy in the disc, margin 

 thin-fleshed. Context pale buff, odor and taste not distinctive. 



Lamellae adnate-decurrent, whitish to buff, 5-8 mm broad, dis- 

 tant. Stipe 5-10 cm long, 5-10(15) mm thick, pale buff to orange-buff, 

 often narrowed below and rooting, straight or flexuous, fibrillose-rough, 

 apex white-floccose, stuffed becoming hollow. Spores 6-8 X 4 ll, un- 

 equally elongate-elliptic. Basidia 26-42 X 6-7 p. 



Habit, Habitat, and Distbibution — Only in beech woods, August 

 and November, not rare, edible. 



Obsebvations — The description above is taken from Niiesch 

 ( 1922 ) . Notes following were made on Smith 52634, from Colorado, a 

 collection which seems to be H. leucophaeus: Spores 5.5-8.5 X 3.5-4.5 fx, 

 ellipsoid, smooth, yellowish in Melzer's reagent. Basidia 44-57 X 6-7 p, 

 mostly 4-spored, a few 2-spored. Pleurocystidia and cheilocystidia none. 

 Gill trama divergent, hyphae 5-11 fi broad. Cuticle of the pileus a ge- 

 latinous zone 70-100 /x broad. Pileus trama of interwoven, more or less 

 radial hyphae. Clamp connections present on the cuticular hyphae of 

 both the pileus and stipe. 



We believe that H. leucophaeus and H. laurae represent still 

 another pair of similarly colored species in section Hygrophorus differ- 

 ing in the presence or absence of a universal veil. It must be remem- 

 bered that H. leucophaeus is a species of the beech woods, and collec- 

 tions of what appear to be H. discoideus from under conifers but 

 having a dry stipe should not be referred to leucophaeus without a 

 very careful study.
