the most closely related species, li.i\e no odor and the taste <>| thru 



flesh is mild or hitter finally. The white stipe showed no yellow tin' 

 even after handling, a character of //. lacmus IV. However, this is the 



nearest to //. lacmus of any North \nierican species we have studied. 

 In the dried specimens the cap has retained the purplish fusOOUS tun. 

 over the marginal area, hut the disc, the gills, and the Stipe show 

 varying tones of cinnamon hud to darker tan.

Hygrophorus nordmanensu, sp. nov. 



Pileus 2 cm lotus, convexo-extensus, "benzo brown" glaber, 

 viscidus, margins striate); cam modice tenuis, odore proprio; stipes 

 2 cm longus, siccus, pallidas; sporae 7-11 x 4.5-5.5 r . eUipsoideae. 

 Specimen tijpicum in Herb. Univ. Mich.; ledum juxta Granite Creek, 

 Nordman, Idaho, Oct. 9, 1956, A. H. Smith 54328. 



Pilens 2 cm broad, convex-expanding, "benzo brown," glabrous, 

 viscid, margin striate. Context medium thin; odor of green corn. 



Lamellae deenrrent, pale drab, becoming dingy hull in age, dis- 

 tant, medium broad. 



Stipe 2 cm long, dry, pallid. 



Spores 7-11 X 4.5-5.5 /a, ellipsoid, smooth, yellow in Mel/ei's 

 reagent. Basidia 38-50 x 5-8 /x, 2- and 4-spored. Pleurocystidia and 

 cheilocystidia none. Gill trama interwoven, hyphae 5-12 /> broad. 

 Cuticle a narrow (20-40 /x) gelatinous zone, hyphae 1.5-3 p broad, 

 repent, radial, not differentiated from the hyphae of the pileus trama. 

 Hypoderminm not differentiated. Pileus trama of radially disposed. 

 snbparallel hyphae. Clamp connections not found. 



Habit, Habitat, and Distbibution — On soil, under hemlock, 

 Idaho, October. 



Matebial Studied — idaho: Smith 54328 (type, from Granite 

 Creek, Nordman, Oct. 9, 1956). 



Obsebvations — This species is related to //. rainierensis, 11. sub- 

 violaceus, and H. lacmus but has longer spores than any of them. The 

 apparent absence of clamp connections may turn out to be an addi- 

 tional difference, but we hesitate to emphasize it because of the small 

 amount of material available for study.
