Boeremia hedericola

Pycnidia in the middle of the leaf affected by the fungus's necrotic lesion; these pycnidia are black, grain-like, glabrous, with a well-defined aperture or ostiole.

Conidiophores virtually non-existent; these would be located on the inner wall of the pycnidium, corresponding to short conidiogenous cells.

Conidia cylindrical to ellipsoidal, hyaline and thin-walled.
