In Brazil, it is com- monly cultivated in the north and northeastern states for commercial exploitation of fruits and pulp. Over five million fruits are harvested each year in Brazil. During a survey of plant diseases in October 2007 in Pacaraima (Roraima State), trees of A. muricata were observed exhibiting necrotic dark brown circular leaf spots, 0Æ7–3Æ0 cm wide, frequently with concentric circles. All plants surveyed presented symptoms in high sever- ity. Microscopic examination revealed an association with a fungus that displayed amphigenous fructification, predominantly on the abaxial leaf surface, and stromata 21–83 lm in diameter.  aAnnonaceae1 aNECHET, K. de L.  tPlant Pathologygv. 5, n. 11, p.411, 2010.
