Dryopteris erythrosora has an erect to short-creeping rhizome, 2-pinnate ovate laminae, and narrowly ovate blackish-brown scales on the stipe. Young fronds are often red-tinged. The scales on the costae are inflated, with long, attenuate apices. The sori are arranged in one row either side of the costae, and the reniform indusia characteristically have red centres (Hoshizaki & Moran 2001).
