Sordariomycetidae O.E. Erikss. & Winka, Myconet 1(1): 10 (1997)

Index Fungorum Number: IF90351

The subclass Sordariomycetidae was established by Eriksson & Winka (1997) and comprised six orders, 12 families and two families incertae incertae sedis. Members of this subclass are mainly characterized by dark ascomata with inoperculate, unitunicate asci and occur in terrestrial, aquatic and marine habitats and are widely distributed as plant and animal pathogens, endophytes, saprobes as well as coprophilous and lichenicolous taxa (Maharachchikumbura et al.al. 2015, 2016b, Huang Huang et al.al. 2019). They are mycophilic, rich in coprophilous taxa and associated with invertebrates and their ecological aspects and biotechnological potential have been researched (Zhang et al.al. 2006, Raghukumar 2008, Bovio et al.al. 2018). An MCC tree based on a combined SSU, LSU, tef1 and rpb2 sequence data revealed that this subclass evolved around 145 –216 MYA (Hongsanan et al.al. 2017, Hyde et al.al. 2017a). The divergence time for Sordariomycetidae is estimated as 247 MYA. Currently, there are eight orders and 19 families in this subclass.
