part of the eastern United States, as well as in Europe. The 
surface is usually decorated with reddish spots or stains, but varie- 
ties occur in which these spots are entirely absent. 
Hygrophorus eburneus (Bull.) Fries 
Ivory Hygrophorus 
Plate 131. X Yi 
Pileus fleshy, moderately thick, sometimes thin, convex to ex- 
panded, 3-8 cm. broad ; surface very viscid or glutinous, com- 
pletely covered with a coating of gluten, entirely white; context 
having a mild and not unpleasant odor; lamellae strongly decur- 
rent, distant, with vein-like elevations near the stipe ; spores ovoid, 
granular 6-10 X 5—6 /x ; stipe spongy to stuffed within, sometimes 
hollow and tapering below, 6-15 cm. long, 3-8 mm. thick. 
This attractive edible species is widely distributed throughout 
the cooler regions of Europe and America, occurring on the 
ground in woods or in partially shaded places. The writer found 
it to be one of the most common and abundant species on the 
Pacific coast. In many localities, a basketful could have been 
gathered in a very small area. Its white color, slimy covering, 
mild odor, and decurrent, distant gills will serve to distinguish it 
from closely related species.

Plate 132. Lower Figure. X V2 
Pileus fleshy, convex-umbilicate, at length infundibuliform, 
4-12 cm. or more in diameter; surface white, azonate, dry, glab- 
rous ; margin involute at first and naked, at length uplifted ; con- 
text compact, white, unchanging or becoming sordid, edible ; latex 
white, unchanging, very acrid, abundant ; lamellae white or 
creamy-white, forking dichotomously, close, more or less decur- 
rent, arcuate at first, then extending upwards, only about 2 mm. 
broad ; spores white, subglobose, nearly smooth, 8-9 ju, in diameter; 
stipe white, equal, dry, often pruinose, solid and firm, 2-8 cm. 
long, up to 2 cm. thick. 
Found in great abundance in oak woods throughout temperate 
North America, as well as in Europe. It contains an acid and a 
resin, “ piperon,” which is extremely acrid in the fresh state, but
