Eburneus is from ebur, ivory. The pileus is two to four inches broad, sometimes thin, sometimes somewhat compact, white; very viscid or glutinous in wet weather, and slippery to the touch; margin uneven, sometimes wavy; smooth, and shining. When young, the margin is incurved.
The gills are firm, distant, straight, strongly decurrent, with vein-like elevations near the stem. The spores are white, rather long.
The stem is unequal, sometimes long and sometimes short; stuffed, then hollow, tapering downward, punctate above with granular scales. Odor and taste are rather pleasant. It is found in woods and pastures in all parts of Ohio, but it is not plentiful anywhere. I have found it only in damp woods about Chillicothe. August to October.
Hygrophorus cossus. Sow.
Cossus, because it smells like the caterpillar, Cossus ligniperda.
The pileus is small, quite viscid, shining when dry, white with a yellow tinge, edge naked, very strong-scented.
The gills are somewhat decurrent, thin, distant, straight, firm.
The stem is stuffed, nearly equal, scurvy-punctate upwards. Spores 8×4. Found in the woods. The strong smell will serve to identify the species.
