Bryoerythrophyllum recurvirostrum is widespread northern hemispheric species known in Central America only from Guatemala. The species is marked by its oblong-lanceolate to lanceolate leaves that have strongly recurved leaf margins, rectangular basal cells, and irregularly dentate upper leaf margins. Bryoerythrophyllum aeneum is similar to B. recurvirostrum in most features, but differs in its dioicous sexuality, firm, thick-walled basal leaf cells, and in having rhizoidal gemmae. Bryoerythrophyllum campylocarpum is similar to this species in leaf shape and in having enlarged, thin-walled inner basal leaf cells. It differs from B. recurvirostrum in having plane upper leaf margins and a distinctive basal leaf border of long, narrow, firm-walled cells.
