Progress toward a modern species-level phylogeny of Geoglossomycetes.

The class Geoglossomycetes (Ascomycota), commonly referred to as earth tongues, currently contains nine genera in one family (Geoglossaceae). Published estimates of species diversity have been mostly local, with current global estimates approaching 70 species in the class. This poster will present the latest results of our attempt at a modern species-level phylogeny of Geoglossomycetes using maximum likelihood and Bayesian analyses of multi-gene sequence alignments (ITS and LSU nrDNA, MCM7, RPB1) along with analysis of morphological characters and ecological associations. Ongoing molecular phylogenetic research indicates that cryptic species, previously unrecognized due to subtle morphological differences and lack of molecular evidence, are widely distributed throughout Geoglossomycetes. Molecular and ecological evidence for higher-level taxonomic changes and the influence of biogeographical factors on speciation is discussed.
