Epifungium

The fragile, whitish shells have a teleoconch sculpture of low costal ribs and spiral threads.
The snails live under fungiid hosts (Fungiidae) on the coral itself or on the substratum underneath When the snails are not on the coral surface, they are usually found on a hard substratum, like coral rubble and only rarely on sand.

A similar teleoconch sculpture of low costal ribs and spiral threads is present in Epidendrium and some Epitonium species.

Etymology: epi [Greek]= on and fungium referring to the coral host family Fungiidae.
