Maximum Likelihood (ML) phylogeny of Helicogloeaceae and allied families based on the LSU nucleotide alignment. The dataset was aligned using MAFFT v. 7.520 ( Katoh & Standley 2013) and the ML tree was calculated in IQ-TREE v. 2.1.3 ( Minh et al. 2020). Best nucleotide substitution models were calculated with ModelFinder ( Kalyaanamoorthy et al. 2017) as implemented in IQ-TREE. The tree was rooted to Sterigmatomyces hyphaenes (CBS 7811, GenBank NG_042408). Values at nodes are ML ultrafast bootstrap ≥ 75 % (based on 10 000 replicates; values ≥ 95 % can be considered significant). The novel taxon is shown in bold and a dark blue block. Families, the order and the class are shown in coloured blocks on the right side of the phylogeny. The basal branch was shortened to facilitate layout.
