Togniniales

Togniniales Senan., Maharachch. & K.D. Hyde

 

Togniniales comprises a single family Togniniaceae based on phylogenetic analyses and it is similar to some members of Calosphaeriaceae in having perithecial ascomata and clavate, tiny asci with hyaline ascogenous hyphae and cylindrical to allantoid ascospores (Maharachchikumbura et al. 2015, Réblová et al. 2015). Togniniaceae was placed in Diaporthales based on SSU and LSU gene analyses (Mostert et al. 2006). However, multi-gene analyses showed that Togniniales as an independent clade with Diaporthales and Calosphaeriales (Maharachchikumbura et al. 2015, 2016, Réblová et al. 2015, Huang et al. 2019). Species of this order have a worldwide distribution and are well-known pathogens of plants and animals (Rooney-Latham et al. 2005, Hoffmann & Voigt 2011, Kredics et al. 2011, Huang et al. 2018). The divergence time for Togniniales is estimated as 138 MYA. Currently there is one family and two genera in this order (Hyde et al. 2020).
