A 50% majority-rule consensus tree of the genus Tinnea obtained from the Bayesian analysis of the combined datasets of the nrITS, and matK, rbcL and trnL-F.
Numbers on nodes indicate the posterior probability and the bootstrap support values of >0.80 and >55% respectively. Note that the new species (T. gombea) is in bold blue.
