Two new rust species on Fabaceae from Brazil
Two new species of rust fungi (Basidiomycota, Pucciniales) on Fabaceae are proposed: Atelocauda sakuraguiae on Ormosia sp. and Ravenelia costae on Pseudopiptadenia leptostachya. Both were collected at the Parque Nacional do Itatiaia,
Brazil. Atelocauda sakuraguiae can be distinguished from all other Atelocauda species on Fabaceae by its non-lobed aeciospores, septate aecial paraphyses, less elongate teliospores, and septate teliospore pedicels. Ravenelia costae can be distinguished from all
other Ravenelia species by its smooth teliospores, probasidia deriving from germ pores, pendent cysts, echinulate urediniospores, and absence of paraphyses.
