Anamorph: Conidiomata pycnidial, 40-80 µm diam, immersed, dark greyish brown, subglobose, opening irregularly without a well-defined ostiole. Wall 9-16 µm thick, brown, paler below, K-, in some parts with a greenish olivaceous pigment, composed of ellipsoidal cells 4-8 x 2.5-5 µm in size. Setae absent. Conidiophores absent. Conidiogenous cells 3-4.5 x 2.5-3.5 µm, ellipsoidal, ampulliform or irregular in shape, tapering towards the apex, arising directly from the inner wall and lining the entire pycnidial cavity, hyaline, non-septate, apparently non-proliferating, without annellations. Conidia abundant, hyaline, smooth- and thin-walled, basally slightly attenuated, transversely septate, elongate, with one main axis which is ± straight, except in the middle region where it is strongly curved (by ca 50-150°), with two lateral branches, one just before and one just after the curved segment, the resulting conidium thus often appearing H-shaped, with four cylindrical 1- to 3-septate arms 18-32 µm long and 1-2.5 µm diam.
