Overview of Sordariomycetes.

The class Sordariomycetes, traditionally referred to as “pyrenomycetes”, consists of three subclasses, Hypocreomycetidae, Sordariomycetidae, Xylariomycetidae, and contains over 1,200 genera and 10,000 species of non-lichenized ascomycetes. Most taxa are united by perithecia and inoperculate unitunicate asci although a few possess cleistothecia and prototunicate asci. Members are ubiquitous throughout all ecosystems occurring as saprobes, endophytes, mycoparasites, and plant, animal and insect pathogens. Phylogenetic relationships at the generic-level and above were estimated by assembling molecular sequence data for two taxa per genus, preferably the type species and another closely related species, from the following five nuclear genes: SSU, LSU, MCM7, RPB2, and TEF-1. The number of sequences per data set ranged from ~120 for MCM7 to nearly 550 for LSU and included ~600 unique taxa representing type species for ~20% of the genera in the Sordariomycetes. Each data set was aligned using PASTA and phylogenetic trees were generated employing both concatenation (FastTree) and coalescent-based (ASTRAL) methods. Evolutionary relationships of higher taxa will be discussed along with proposed changes to the existing taxonomic classification of the class.
