Index Fungorum number: IF 812184
Tirisporellaceae (Suetrong et al. 2015) accommodates three monotypic genera, Bacusphaeria (Abdel-Wahab et al. 2017), Thailandiomyces (Pinruan et al. 2008) and Tirisporella (Jones et al. 1996). The family is characterized by large, black perithecial, ostiolate ascomata, a thick-walled peridium, cylindrical asci, 1–7-septate, fusoid ascospores with or without appendages and Craspedodidymum and Phialophora-like asexual morphs (Jones et al. 2015, Suetrong et al. 2015, Maharachchikumbura et al. 2016, Hyde et al. 2020a). An updated phylogeny for Tirisporellales is provided.
Fig – Phylogram generated from maximum likelihood analysis based on combined LSU and SSU sequence data of taxa in Tirisporellales. Twenty-nine strains are included in the combined analyses which comprised 1861 characters (845 characters for LSU, 1016 characters for SSU) after alignment. Tree topology of the maximum likelihood analysis is similar to the Bayesian analysis. The best RaxML tree with a final likelihood value of -4201.831746 is shown here. Estimated base frequencies were as follows: A = 0.243036, C = 0.242271, G = 0.307289, T = 0.207404; substitution rates AC = 0.625317, AG = 1.610478, AT = 0.601945, CG = 0.831636, CT = 4.876660, GT = 1.000000; gamma distribution shape parameter α = 1.078289. Bootstrap support values for ML and MP greater than 75% and Bayesian posterior probabilities greater than 0.95 are indicated in bold branches. The tree is rooted with Togninia novae-zealandiae (CBS 110156) and T. fraxinopennsylvanica (CBS 101585). Ex-type strains are in bold and black. The newly generated sequences are indicated in yellow.
