Uredinales do estado do Pará.

Abstract

The order Uredinales comprises the fungi of the subdivision Basidiomycotina called rusts. More than 5000 species are known to be distributed worldwide. In the Brazilian Rust Index, 150 species are cited, belonging to 49 genera. A survey of materials deposited in the João Murça Pires (MG) and CPATU/EMBRAPA (IAN) herbaria was carried out, followed by field collection and bibliographic research. The species were identified or updated taxonomically with the help of specialized literature. Until now, the order Uredinales is represented for the State of Pará by 82 species included in the genera: Aecidium (5); Apra (1); Cerotelium (1); Chaconia (1); Coleosporium (2); Crossopsora (3); Dasyspora (1); Dicheirinia (1); Maravalia (3); Olivea (1); Phakopsora (3); Physopella (1); Porotenus (2); Prospodium (1); Puccinia (28); Pucciniosira (1); Ravenelia (1); Sorataea (2); Sphenospora (2); Uredo (12); Uromyces (9); Uropyxis (1). The list of specimens studied comprises 50 species, 12 of which are deposited in the herbarium of the Museu Paraense Emílio Goeldi (MG) and 38 in the Instituto Agronômico do Norte (IAN). A bibliographical survey found 32 more species mentioned as occurring in Pará, but deposited in other herbariums. The list of Pará rust species will be presented, with host indication, collection site in the State and citation of the herbaria in which the Uredinales are deposited (CNPq/MPEG).
