Sori superficial or submarginal, terminal on free veinlets, circular or forming linear compound marginal sorus; indusium cup-shaped or 2-lipped (outer lip formed by recurved margins of lamina; inner lip a true indusium, membranous, delicate, sometimes reduced or absent); annulus usually vertical; spores tetrahedral or bilateral.

About 12 genera, mostly from tropical regions; 5 occurring in Australia, with Oenotrichia not represented in Victoria.
