The rust fungi of Luzuriaga (Luzuriagaceae) with description of a new species, Puccinia luzuriagae-polyphyllae.

摘要

Three species of rust fungi (Uredinales), Puccinia perforans, P. fuegiana (=Uromyces skottsbergii), and Aecidium callixenis have been described on members of Luzuriaga (Luzuriagaceae). Puccinia luzuriagae-polyphyllae is added as a new species on Luzuriaga polyphylla from Chile. The rust had been confused hitherto with P. perforans occurring on L. radicans. Both species differ from P. fuegiana on L. marginata by the absence of a uredinial state and several telial characters. The investigated collections of Puccinia species on Luzuriaga indicate that each is restricted to a single host species. A determination key is presented.
