F.  aReport of Paramyrothecium roridum causing circular leaf spots on impatiens walleriana in Brazil.h[electronic resource]  c2019  aGarden impatiens (Impatiens walleriana Hook. f., Balsaminaceae) has been largely employed as a flowering (ornamental) potted species in Brazil, being propagated by either cuttings or seeds. In August 2016, commercial container-grown I. walleriana plants exhibiting dark brown, circular to semicircular leaf spots (0.5 to 10 mm diameter) were found in commercial nurseries in Atibaia (São Paulo State, Brazil). Under high humidity, the abaxial surface of the lower leaves displayed black sporodochia. Leaf fall was observed a few days after the beginning of the symptoms. Approximately 30% of the plants were unsuitable for sale. Symptomatic tissues were disinfected using 70% alcohol for 1 min and 2% sodium hypochlorite for 1 min, followed by a double rinse in sterilized distilled water for 1 min.  aBalsaminaceae  aDoença de Planta  aFungo  aParamyrothecium roridum1 aSANTOS, M.
