SUBSECTION CAMAROPHYLL1 359 



Pleurocystidia and cheilocystidia none. Gill trama divergent, hyphae 

 3-8 jx broad. Cuticle an ixotrichodennium, hyphae more or less erect 

 and tangled, 2.5-5 fx broad, at times finally repent and then resembling 

 an ixocutis. No hypodermium differentiated. Pileus trama of radial hy- 

 phae. Clamp connections on the hyphae of the cuticle and gill trama. 

 Lactifers present in the gill trama. 



Habit, Habitat, and Distribution — Densely gregarious under 

 spruce, Idaho, California, and Washington, November; also Canada. 



Material Studied — California: Smith 8518, 8581, 8732 (type, 

 Fort Dick, Nov. 14, 1937), 9054, 9485. idaho: Smith 54790. washing- 

 ton: Kauffman, Lake Quinault, Nov. 3, 1925. Canada: (Nova Scotia) 

 Harrison Kings Co., Sept. 21, 1955. 



Observations — During the season of 1937 this species was very 

 abundant in the vicinity of Fort Dick, California. Kauffman collected 

 it in Washington in 1925. The large spores, dry stipe, russet to tawny 

 colors, mild taste, and strong aromatic odor distinguish it. Kauffman 

 tentatively referred it to H. agathosmus as a variety. It does resemble 

 that species in having an odor and a dry stipe, but the colors of both the 

 pileus and gills, and the large spores amply distinguish it. It is appar- 

 ently very closely related to the little known H. aromaticus (Sow.) 

 Berk. The latter apparently differs in its narrow, white to pink gills, 

 and the flesh which is said to turn blackish when bruised.

 ders appreciably; odor of cherry pits, taste mild. 



Lamellae decurrent, whitish, in age becoming flushed with color
