The gills are attached to the stem with a decurrent tooth, thin, whitish or tinged with gray.
The stem is two to four inches long, hollow, tough, rooting, viscid, yellowish, sometimes gray or even whitish. The spores are elliptical, 8–10×4–5µ.
These plants have a wide distribution and are found on branches, among moss and dead leaves. They are found in clusters and solitary. They resemble in many ways M. alcalina but do not have the peculiar smell.
The plants in Figure 96 were photographed by Prof. G. D. Smith of Akron.
Omphalia. Fr.
Omphalia is from a Greek word meaning the navel; referring here to the central depression in the cap.
The pileus from the first is centrally depressed, then funnel-shaped, almost membranaceous, and watery when moist; margin incurved or straight. Stem cartilaginous and hollow, often stuffed when young, continuous with the cap but different in character. Gills decurrent and sometimes branched.
They are generally found on wood, preferring a damp woody situation and a wet season. It is easily distinguished from Collybia and Mycena by its decurrent gills. In some of the species of the Mycena where the gills are slightly decurrent, the pileus is not centrally depressed as it is in corresponding species of Omphalia. There are a few species of Omphalia whose pileus is not centrally depressed but whose gills are plainly decurrent.
