Decaying wood of fir trees. Camas,, February. Yeomans. 
The small size, buff pileus solid stem and pallid lamellae.are 
the distinguishing features of this species. It is closely related to 
O. Campanella, but the paler colors of the pileus and lamellae and 
the white mycelium will separate it. The stem appears to be 
solid, but it is possible that in fully mature specimens there may 
be a small cavity. 
LACTARIUS LUTEOLUS. 
Pileus fleshy, rather thin, convex or nearly plane, commonly 
umbilicately depressed in the center and somewhat rugulose, 
pruinose or subglabrous, buff color, flesh white, taste mild, milk 
copious, flowing easily, white or whitish; lamellae close, nearly 
plane, adnate or slightly rounded behind, whitish, becoming 
brownish where wounded; stem short, equal or tapering down- 
ward, solid, but somewhat spongy within, colored like the pileus; 
spores globose, .0003 in. broad; pileus 2-3 in. broad; stem I-1.5 
in. long, 3-5 lines thick.

Webster. 
This species is related to Lactarius volemus and L. hygropho- 
voides, but its smaller size and short stem will distinguish it from 
the former and its close lamellae from the latter. Its paler buff 
color will separate it from both. Some specimens have a narrow 
encircling furrow or depressed zone near the margin and a 
slightly darker shade of color on the margin. The milk consti- 
tutes a remarkable feature of the species. According to the notes 
of the collector it is exceedingly copious, rather sticky, serous in 
character with white particles in suspension. It flows from many 
points as soon as the plant is disturbed and it stains the gills. It 1s 
impossible to collect an unstained specimen, so free is the flow of 
the milk. He says, “I have never succeeded in picking a spec! 
men so quietly as to prevent an instant and copious flow of its milk.” 
RUSSULA SUBDEPALLENS. 
Pileus fleshy, at first convex-and ‘striate on the margin, then 
expanded or centrally depressed and tuberculate-striate on the 
“margin, viscid, blood-red or purplish red, mottled with yellowish 
spots, becoming paler or almost white with age, often irregular, 
flesh fragile, white, becoming cinereous with age, reddish under 
the cuticle, taste mild; lamellae broad, subdistant, adnate, white —
