322 SECTION HYGROPHORUS 



veil. It is significant that he clearly aligned it to H. eburneus "Ce 

 Limacium est certainement voisin de Hygrophorus eburneus. . . ." 

 Kiihner and Romagnesi say of the droplets on the stipe "non gluti- 

 neuses" but report it under beech. 



With the discovery of H. tenax and previous knowledge of the 

 color changes that take place on the gills of H. variicolor and 

 H. baker ensis on drying, it must now be admitted that there are a 

 number of species known with the color change of H. chrysaspis. We 

 limit our recognition of H. chrysaspis to a fungus of the conifer forests, 

 odorless, and with a gelatinous veil and the epicutis of the pileus as 

 given above. 



The account of Kiihner and Romagnesi ( 1953, p. 58 ) might apply 

 to H. pseud ochrysaspis. This question needs to be investigated.

Hygrophorus subpungens Sm. & Hes. 



Sydowia 8: 312. 1954 



Pileus 1.5-3(4) cm broad, obtuse when young, the margin in- 

 curved, soon nearly plane or with just a trace of an obtuse umbo, in 

 age the disc depressed as a result of the uplifting of the margin, 

 viscid, dull white ("tilleul buff") at first, gradually darkening on the 

 disc in age to near pale avellaneous, the margin remaining dingy 

 whitish. Context thin, soft, dull white, unchanging or gradually be- 

 coming vinaceous buff to avellaneous; odor faint but spicy-fragrant, 

 taste mild. 



Lamellae broadly adnate and becoming short-decurrent, sub- 

 distant to nearly close, one tier of lamellulae, moderately broad, dark 

 "tilleul buff" young (pallid), becoming "cinnamon-buff" and in age 

 nearly clay color, edges even. 



Stipe 2.5-4 cm long, 3-7 mm thick, equal, sometimes hollow in age, 

 dry, whitish and pruinose over all at first, glabrescent, becoming dingy 

 where handled but never as dark as the old gills. 



Spores 7-8 X 4.5-5 /x, elliptic in face view, in side view slightly 

 bean-shaped, smooth, yellowish in Melzer's reagent. Basidia 4-spored, 

 44-56 X 7-8 p, basidia in sections of hymenium revived in KOH dull 

 pale cinnamon in color. Pleurocystidia and cheilocystidia none. Gill 

 trama divergent, hyaline, hyphae 4-7 /x broad. Cuticle a gelatinous 

 zone 70-120 ^ thick, hyphae repent, radial, 2-3 /x broad, an ixocutis. No 

 hypodermium differentiated. Pileus trama of radial hyphae, 4-10 /x 

 broad. Clamp connections present. 



Habit, Habitat, and Distbibution — Densely gregarious on wet 

 soil near a beaver pond, Oregon, October.
