Notes:—
Hercospora
Fr.
comprises 15 species (
Index Fungorum 2016
) with
Hercospora tiliae
as the
type
. The characters of the genus include eustromatic, immersed, subepidermal, dark blackish brown, separate, uniloculate, multiloculate or convoluted and thick-walled conidiomata; conidiophores branched extensively at the base, less so above, hyaline, septate, smooth, often developing in mucilage, formed at the base and sides of the conidiomatal wall; and ellipsoid, thick-walled, hyaline, aseptate conidia (18–20 × 6–7.5 μm) (
