The stem is stuffed, then hollow, even, tough, pale-tawny. The spores are 7–8×5–6µ.

The plants are usually hygrophanous, but when dry, floccose or slightly silky. This is a small plant growing usually on lawns, nearly hidden in the grass. I found some very fine specimens on Dr. Sulzbacher's lawn on Second Street, Chillicothe. The plant is, however, widely distributed. I found many specimens on the 3d of November.

Figure 99.—Omphalia fibula.

Fibula means a buckle or pin, from the pin-like stem.

The pileus is membranaceous, at first top-shaped, expanded, slightly umbilicate, striate, margin inclined to be inflexed, yellow or tawny, with a dusky center, minutely pilose.

The gills are deeply decurrent, paler, distinct.
