smooth, glabrous, dry, somewhat shining, margin entire, concol- 
orous; lamellae decurrent, distant, rather narrow, white to

members of this group, its appearance indicating ferruginous 
rather than hyaline spores.

Pileus convex to subexpanded, umbonate, terraced, reaching

ently viscid when fresh, bringing up adhering particles of sand ; 
context mild to the taste, but with a strong, unpleasant odor ; 
lamellae sinuate, ventricose, crowded, pallid, becoming discolored 
with subferruginous blotches ; spores globose or subglobose, 
smooth, hyaline, with granular contents, about 4/4; stipe long, 
slightly attenuate downward, fleshy, white, glabrous, except for 
a few fibrils where the margin of the pileus rested against the 
stipe, reaching 10 cm. long, and 2 cm. thick.
