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 2015, 2016b, Huang Huang et 2019). They are mycophilic, rich in coprophilous taxa and associated with invertebrates and their ecological aspects and biotechnological potential have been researched (Zhang et 2006, Raghukumar 2008, Bovio et 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 2017, Hyde et 2017a). The divergence time for Sordariomycetidae is estimated as 247 MYA. Currently, there are eight orders and 19 families in this subclass.
