Abstract: plants located in Vicosa, Minas Gerais State, Brazil(Figure 1A). The spots were circular, with well-defined edges, gray atthe center, surrounded by a concentric dark reddish-brown ring, withapproximately 0.8 cm in diameter, where acervuli could be observedon the center of the lesion. The lesions evolved into necrotic tissues,which eventually may be detached. A highly pigmented region wasobserved around the lesions with a reddish-brown color, suggesting aplant defense response (Figure 1B). The causal agent of the diseasewas isolated and cultured on potato dextrose agar (PDA). Followingits development, microscopic preparations were made. Conidialdimensions were 10 – 25 x 2.5 – 3.7 µm and appressorium dimensionswere 7.5 – 15 x 5 – 8.7 µm. In accordance with standards ofmorphological characterization in the literature, the fungus wasidentified as
