Abstract

Four new species of rust fungi (Basidiomycota, Uredinales) are proposed: Edythea soratensis on Berberis phyllacantha (Berberidaceae), Prospodium bicristatum on Mansoa sp. (Bignoniaceae), Uromyces cearensis on Ipomoea sp. (Convolvulaceae) and Uredo cavernula on Ribes weberbaueri (Grossulariaceae). U. cavernula most probably belongs to the genus Goplana. Phakopsora phyllanthi and Phakopsora vernoniae are newly reported for Brazil and the New World. The uredinial stage of the latter is the same as Uredo toroiana, known so far from Hispaniola in the Caribbean. The parasitic mycelium of Esalque holwayi was studied. It is strictly intracellular but comprises well-defined haustoria and intracellular hyphae.
