Type species – Daldinia concentrica Ces. & De Not.
Notes – The genus was revisited and redefined by Stadler et al. (2014) and later included in Hypoxylaceae because of its affinities with Hypoxylon. Most species are characterized by well- defined concentric zones in the stromatal interior (Stadler et al. 2014). Multigene phylogeny studies showed that the genus comprises two well-supported clades within the family (Daranagama et al. 2018, Wendt et al. 2018). Daldinia eschscholtzii is illustrated in this entry (Figs. 126, 127).
