Abstract

Pucciniamodiolae, a rust fungus pathogen of Carolina bristlemallow, Modiolacaroliniana (Malvaceae), is newly reported from North America, appears to be well established along the Gulf coast and is likely to have been introduced from South America. Its taxonomy, distribution and natural host range are discussed and a lectotype designated for this species. Malvasylvestris and Alcearosea are reported as new hosts for the rust. Additional new records for Malvaceae rusts are made for P.modiolae on Alcearosea from Brazil, P.heterospora on Herissantiacrispa in Florida and P.heterogenea on Malva sp. in Peru. Finally, an identification key for the microcyclic Puccinia species on members of Malvaceae in North America is provided.
