Leucosporae 



Often umbilicate. Remarkable for the few and distant gills. Stevenson. Hygrophorus. 

 Spores loxSfj. Cooke. 



Caps white, shaded to light pinkish-brown toward center. Gills very 

 distant. Leaves adhere to cap. 



Specimens tested were of mild, pleasant flavor. 



H. sphsero'sporus Pk. Pileus fleshy and thick in the center, sub- ; 



obconic, convex, obtuse or slightly umbonate, whitish, inclining to red- 

 dish-brown, the margin incurved. Flesh firm, white. Gills rather 

 broad, subdistant, adnate or slightly decurrent, white. Stems tufted, 

 flexuous, solid, glabrous, often slightly thickened at the base, colored 

 like the pileus. Spores globose, 6 Sp, broad.

Iowa. October. Communicated by C. Mcllvaine. 



The fresh plant is said to have no decided odor, but when partly dried 

 it emits a slight but rather unpleasant odor. It belongs apparently to 

 the section Camarophyllus, and is related to Hygrophorus Peckii. 

 Peck, Torr. Bull., Vol. 22, No. 12. 



Received by the writer from Hon. Thomas Updegraff, MacGregor, 

 Iowa, and forwarded to Professor Peck as a new species. 



The fungus has but slight taste and is without odor when fresh. 



It is probably edible. Not received in sufficient quantity to test.

H. cera'ceus Fr. cera, wax. Pileus about i in. broad, waxy-yel- 

 low, shining, slightly fleshy, thin, but slightly firm, convexo-plane, 

 obtuse, slightly pellucid-striate, viscid. Stem 1-2 in. and more long, 

 about 2 lines thick, hollow, often unequal, flexuous and at length com- 

 pressed, even, smooth, of the same color as the pileus, never darker at 

 the apex. Gills adnato-decurrent , broad, almost triangular, distinct,

 able) color. Stevenson.
