Type species – Libertella betulina Desm.

Notes – Libertella was introduced by Desmazières (1830) to accommodate L. betulina, L. faginea and L. rosae. This genus was mostly reported as the asexual morph of Diatrypella, however, some species were reported as asexual Eutypa, Eutypella, Diaporthe, and Polystigma (Kirk et al. 2001). The genus is characterised by subcortical, erumpent, and yellow to red acervula conidiomata and branched conidiophores that produce hyaline, 1-celled, filiform conidia (Barnett & Hunter 1972, Sutton 1980, von Arx 1981b).
