The plants are usually smaller, many of them being of small size, the cap is usually bell-shaped, rarely umbilicate, but what is a more important character the margin of the cap in the young stage is straight as it is applied against the stem, and not at first incurved as it is in Collybia, when the gills and margin of the pileus lie against the stem.

Some of the species are apt to be confused with certain species of Omphalia in which the gills are but slightly decurrent, but in Omphalia the pileus is umbilicate in such species, while in Mycena it is blunt or umbonate.

In the small species of Mycena where the gills are slightly decurrent, the pileus is not umbilicate as it is in corresponding species of Omphalia.
