Saprobic on branches and twigs of temperate trees. Sexual morph: Stromatic tissues prosenchymatous around perithecia, delimited externally by blackened dense pseudoparenchymatous zone, interior whitish, composed of interwoven hyphae mixed with substrate cells. Ascomata perithecial, few, small, circinate, beaks converging, becoming united and erumpent through stroma surface as single large opening. Asci 8-spored, unitunicate, broadly cylindrical. Ascospores hyaline, broadly ellipsoid, one septate, wall smooth, without gelcoating, with narrow terminal and median appendages in some species. Asexual morph: Rabenhorstia sp. , Stromata prosenchymatous. Conidiomata pycnidial, uniloculate, ostiolate, ostiole surrounded by a superficial cap of sterile tissues. Conidiophores elongate. Conidia hyaline ovoid to ellipsoid, one-celled.

Type species:— Hercospora tiliae (Pers.) Tul. & C. Tul.

Notes:— Fries (1825) listed Sphaeria tiliae Pers. , and Sphaeria atrovirens Alb. & Schwein. , as two of the species in Hercospora . However morphologically S. tiliae has hyaline ascospores while S. atrovirens comprising opaque ascospores. Tulasne and Tulasne (1863) accepted H. tiliae as the type species of Hercospora . Petrak (1938) and Ruhland (1900) implicated Rabenhorstia tiliae (Pers.) Fr. , as the asexual morph of Hercospora tiliae . Fourteen species listed under Hercospora ( Index Fungorum, 2016) .
