(Apocynaceae) JF - Scientific Electronic Archives JA - Sci. Electronic Arch VL - 15 IS - 8 SE - Ciências Agrárias DO - 10.36560/15820221589 UR - https://sea.ufr.edu.br/SEA/article/view/1589 SP - AB - <p><em>Phakopsora euvitis</em> is a phytopathological fungal species described in plants of <em>Vitis</em> sp. This study aimed to report the first case of fungal infestation of <em>P. euvitis</em> in the botanical genus <em>Plumeria</em>, <em>Plumeria rubra</em> in Rio Verde, Goiás, Brasil. Leaves showing <em>P. euvitis</em> urediniospore infestation were collected at Instituto Federal Goiano, Rio Verde, Goiás, Brasil, in the gardens of the central library. The plant and fungal species were identified by a specific dichotomous key for both genera. Slides were prepared with glycerin and micrographed under an optical microscope. As for the dimensions of <em>P. euvitis</em> urediniospores in this study, they presented length and width of 15.12 – 24.47 <em>x</em> 13.11 – 15.69 µm, sessile with slightly elongated peduncles, some abruptly elongated, ovoid, ovoid-ellipsoid and oblong-ellipsoid in only one hemisphere. Further studies should be carried out evaluating by histology the areas infected by <em>Phakopsora euvitis</em> in <em>Plumeria rubra</em> to understand the option of this fungus outside the genus Vitis and its evolution in this botanical species. <strong> </strong></p> ER -
