Tracyllalales Crous, Persoonia 40: 365 (2018)
Hernandez-Restrepo et al. (2016a) placed Tracylla aristata within Sordariomycetidae
incertae sedis based on LSU and ITS sequence data. With the description of a new species of
Tracylla from Eucalyptus urophylla in Colombia, Crous et al. (2018d) introduced Tracyllalales to
accommodate the monotypic family Tracyllaceae. Multigene phylogenetic analysis (ITS, LSU,
SSU) of T. aristata and T. eucalypti group these taxa in a well-supported clade distinct from known
orders within Sordariomycetidae. Tracyllalales is closely related to Chaetosphaeriales. The
divergence time for Tracyllalales is estimated as 154 MYA (Fig. 2). Currently there is one family
with one genus in this order (Hyde et al. 2020)
