338 SECTION HYGROPHORUS 



changing to delicate pink under the cuticle or around the edges of in- 

 juries, fragile, taste mild, odor faintly fragrant. 



Lamellae bluntly adnate, becoming subdecurrent, close to subdis- 

 tant, white, broad (1-1.3 cm). 



Stipe 10-18 cm long, 10-25 mm thick, white over all, base staining 

 rusty yellow, solid, equal to subventricose, whitish within, surface 

 densely white floccose-squamulose above, appressed-fibrillose below, 

 slightly viscid (tacky) at the base when wet. 



Spores 8-10 X 5-6 /x, ellipsoid smooth. Basidia 4-spored. Pleurocys- 

 tidia and cheilocystidia none. Gill trama divergent, hyphae 4-7 /x broad. 

 Cuticle a gelatinous zone, 275-400 ti thick, with a narrow zone of brown 

 (in KOH), surface hyphae, beneath which is a tangled zone of colorless 

 hyphae, an ixocutis. No hypodermium differentiated. Pileus trama of 

 interwoven, radial hyphae. Clamp connections present on the hyphae 

 of the cuticle, the pileus trama, and the cuticle. 



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

 redwood, California, December. 



Material Studied — California: Smith 3685 (type, Trinidad, 

 Dec. 1, 1935). 



Observations — Since first collecting this form under spruce in 

 northern California, H. fragrans has been found in great abundance, 

 and the context was never observed to change to the colors described 

 above. It thus seems advisable to consider this variant as representing 

 a distinct color form of the species.
