Entomosporium mespili appears to be a hemibiotroph on infected Photinia leaves. This fungal pathogen produced distinctive haustoria in living host cells in young lesions. Each haustorium possessed a long slender neck with a single septum and an enlarged distal body that contained a single nucleus. A collar of host cell wall material was associated with the haustorial neck. Intact haustoria also were found in necrotic cells of older lesions. However, by this stage of disease development, the pathogen also possessed an extensive system of branched, septate hyphae that grew indiscriminately between and through dead and dying host cells. These hyphae eventually gave rise to a subcutaneous layer of sporogenous cells that formed conidia.
