The Elsinoaceae is a family of fungi primarily known for causing plant diseases, particularly scab and spot diseases on a variety of crops and ornamental plants. Members of this family are mostly plant pathogens, infecting leaves, stems, and fruits, and often producing characteristic lesions or scabby areas. They belong to the order Myriangiales within the class Dothideomycetes, and their life cycle typically includes both sexual and asexual stages, with spores serving as the primary means of spread. Economically, Elsinoaceae species are significant due to their impact on horticultural and agricultural plants, including citrus, grapes, and various ornamental species, making them important targets for plant disease management and research.
