Pucciniosira is a genus of rust fungi belonging to the family Pucciniosiraceae.
The type species is Pucciniosira triumfettae which is now Pucciniosira pallidula.Organization for Flora Neotropica
The Pucciniosira species are characterized by having Puccinia-like teliospores that are produced in chains alternately with intercalary cells. The sori have a continuous to rudimentary peridium (protective layer). In some species, the teliospores break easily into halves along their septa. They form circular groups of rust spores on the lower surfaces of the leaves of various species of plants (including solanum species).U.S. Department of Agriculture
