Species of Uromyces (Pucciniales, Basidiomycota) on Loranthaceae

Two new species of Uromyces with reticulated teliospores are compared with nine species of this genus known from Loranthaceae. The new species Uromyces bahiensis from Brazil has smaller spores than all known species of Uromyces with reticulate teliospores on Loranthaceae. Uromyces struthanthi from Panama is characterized by long teliospore pedicels and spinose-echinulate aecidiospores. In addition, new details of ornamentation of aecidiospores and teliospores of known species are presented.
