Theissenia rogersii deviates from known Theissenia species primarily in having large ascospores with a thick wall layer and a unique configuration of two stromatal tissue types, one carbonaceous and the other fibrous. The carbonaceous tissue forms palisades on and beneath the perithecial layer as well as encasing individual perithecia, whereas the fibrous tissue fills the spaces between columns of the palisades as well as between encased perithecia. Phylogenetic analyses based on DNA sequences of beta-tubulin and alpha-actin genes placed Theissenia in the subfamily Hypoxyloideae among the genera that are characterized by having bipartite stromata (i.e. with the stromata differentiated into an outer dehiscing layer and an inner perithecium-bearing layer).

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
