New anamorphic species of Pucciniales (Fungi, Basidiomycota) collected in the Itatiaia National Park, Brazil

Authorship SCIMAGO INSTITUTIONS RANKINGS

Abstract

Eight new anamorphic species of Pucciniales belonging to the genera Aecidium, Caeoma, Malupa, Milesia, Physopella and Uredo are proposed. The new species were collected in the Itatiaia National Park in the states of Minas Gerais and Rio de Janeiro, Brazil, on the plant families Annonaceae, Apocynaceae, Euphorbiaceae, Menispermaceae, Salicaceae, Solanaceae and Verbenaceae.

Key words
