A new Ophiodothella species associated with leaf spots on Annona squamosa in Brazil

Abstract

A new species of Ophiodothella, O. annonae (Phyllachoraceae, Ascomycetes) is described and illustrated. The fungus causes brown lesions on leaves of Annonae squamosa, which can fall off prematurely, and is characterized by fusiform, slightly curved, biguttulate ascospores with a conspicuous central concentration of cytoplasm. This is the first species of Ophiodotella found on leaves of Annonaceae in Brazil.
