, a new genus of neotropical rust fungi.

Two Cerrado rust fungi, and , described in 1993 and 1995 and originally assigned to families Phakopsoraceae and Ochropsoraceae, respectively, were subjected to molecular phylogenetic analyses using fragments of the nuc 28S and 18S rDNA and mitochondrial cytochrome oxidase subunit 3 (CO3) gene. Although both taxa were morphologically well placed in their original genera, they were shown to belong in a strongly supported new lineage within the Raveneliineae distant from the Phakopsoraceae and Ochropsoraceae. Therefore, we properly treated this lineage as the new genus now harboring (type species) and .

, a new genus of ravenelioid rust fungi on (Caesalpinioideae) from the Brazilian Cerrado and Caatinga.

The multicellular discoid convex teliospore heads represent a prominent generic feature of the genus . However, recent molecular phylogenetic work has shown that this is a convergent trait, and that this genus does not represent a natural group. In 2000, a rust fungus infecting the Caesalpinioid species Ce (= ) was described as .
