    The shaggy plants grow upright, with pinnate but often somewhat 1-sided branching. The broad, falcate leaves are irregularly wrinkled, both longitudinally and transversely. The costa is single, and the long, narrow, pitted cells often project at the upper ends at back as coarse papillae. The species is represented by fmiting material in Tamauhpas. Elsewhere in its broad range it rarely forms sporophytes.
