Six species of rust fungi Diorchidium copaiferae, Ravenelia hieronymi, Sphaerophragmium acaciae, Esalque holway, Uredo sp. and Uromyces neurocarpi were taxonomically studied. In addition, corrections were made in their original descriptions with morphological characteristics. Most of the species were new and illustrated for the first time in optical and scanning electron microscope. All exsiccates were deposited in the Micological Collection for Refference of the Universidade de Brasília.
