Notes – Jaklitsch & Voglmayr (2017) designated a lectotype based on morphological characters and phylogenetic analysis. It is characterized by superficial, globose, subglobose or pyriform, black ascomata, septate pseudoparaphyses, bitunicate, cylindrical, subclavate asci and ellipsoid, pale to medium brown, muriform ascospores with (3)5–7(8) transverse septa and 1–3 longitudinal septa (Jaklitsch & Voglmayr 2017). The asexual morph of Praetumpfia obducens always occurred on bark while sexual morph was on attached branches (Jaklitsch & Voglmayr 2017). Praetumpfia obducens is regarded as host specific for Fraxinus, and damages trees to some extent (Petrak 1927, Jaklitsch & Voglmayr 2017).
