Symptoms and signs (pycnidia) caused by Phyllosticta spp. on leaves: A) tan spots with darker brown border, caused by Phyllosticta sp. on pawpaw (Asimina triloba) leaves; (B) leaf lesions with pycnidia of P. cotoneaster on Cotoneaster sp. Similar symptoms and signs are caused by P. solitaria on its hosts. Apple blotch symptoms caused by Phyllosticta arbutifolia, a taxon closely related to P. solitaria, on Malus domestica fruits: (C) blotchy lesions with pycnidia (red arrows), (D) reddish to brown blotches.

Molecular and morphological characterization of four new Phyllosticta species (Botryosphaeriales, Phyllostictaceae): Genomic insights into evolutionary dynamics and metabolic adaptation The genus Phyllosticta comprises diverse plant-associated fungi, many of which are significant pathogens or endophytes with complex taxonomic histories. Traditional classification, reliant on morpholo...
