The maximum-likelihood phylogram of Nigrograna based on a combined SSU, LSU, ITS, rpb2 and tef1-α sequence dataset with Cyclothyriella rubronotata CBS 141486 and CBS 419.85 as the outgroup taxa (Dayarathne et al. 2020). The maximum-likelihood bootstrap values (ML ≥ 60%, left) and Bayesian Inference Posterior Probability values (BIPP ≥ 0.90, right) are shown above the nodes. Strains derived from the current study are in blue, while type strains are in bold.
