In the genus Claudopus, recognized by some, the pileus is eccentric or lateral, that is, the stem is attached near the side of the cap, or the cap is sessile and attached by one side to the wood on which the plant is growing; or the plants are Resupinate, that is, they may be spread over the surface of the wood.

In Crepidotus the pileus is lateral, or eccentric, and thus more or less shelving, or it is Resupinate, that is, lying flat or nearly so on the wood.

In the Resupinate forms the cap is attached usually near one side, and then is produced more at the opposite side, so that it is more or less lateral or eccentric.
