Berger, F., Zimmermann, E. & Brackel, W. v. 2020. Species of Pronectria (Bionectriaceae) and Xenonectriella (Nectriaceae) growing on foliose Physciaceae, with a key of the Central European species. – Herzogia 33: 473 – 493.

Confusion about the identity of Xenonectriella leptaleae (J.Steiner) Rossman & Lowen led us to revise Central European material of the hypocrealean genera Pronectria and Xenonectriella growing on foliose Physciaceae to clarify the taxonomy. Consequently, we reinstate Pronectria leptaleae and describe Pronectria etayoi, Xenonectriella physciacearum and X. zimmermanni as new species. The new combination Xenonectriella angulospora is proposed. A key to the species of the genera Pronectria and Xenonectriella growing on Physciaceae in Europe is provided.
