This order consists of two families Coniochaetaceae representing the genera Barrina and
Coniochaeta and Cordanaceae which accommodates Cordana. Cordanaceae was previously
classified in Cordanales, however based on molecular clock evidence Hongsanan et al. (2017)
treated Cordanales as a synonym of Coniochaetales. The phylogenetic tree presented here supports
this synonymy (Fig. 9). The divergence time for Coniochaetales has been estimated as 131 MYA
(Fig. 2). Currently there are two families and five genera in this order (Hyde et al. 2020).
