Lopadostoma is typified by Lopadostoma turgidum and consists of 12 accepted 12 species from Europe (Jaklitsch et al. 2014). Lopadostoma species are saprobes which produce pseudostromatic sexual morphs and libertella-like asexual morphs. The species delimitation of Lopadostoma is provided in low resolution using ITS and LSU, however, incorporating protein-coding regions in the phylogeny together with secondary metabolites are important (Jaklitsch et al. 2014, Daranagama et al. 2016).

Fig. 1 – Phylogram generated from maximum likelihood analysis based on combined ITS, LSU and RPB2 sequence data. Forty four strains are included in the combined analyses which comprised of 2680 characters (673 characters for ITS, 847 characters for LSU, 1160 characters for rpb2) after alignment. Tree topology of the maximum likelihood analysis is similar to the Bayesian and maximum parsimony analyses. The GTR+G+I evolutionary model was used for all the gene regions. model The best RaxML tree with a final likelihood value of -13068.839950 is presented. Estimated base frequencies were as follows: A = 0.252657, C = 0.247278, G = 0.267172, T = 0.23289; substitution rates AC = 1.514605, AG = 3.481258, AT = 1.196874, CG = 0.965675, CT = 6.380742, GT = 1.000000; gamma distribution shape parameter ɑ = 0.622728. Bootstrap support values for ML and MP greater than 50% and Bayesian posterior probabilities greater than 0.9 are given near nodes respectively. The tree is rooted with Xylaria hypoxylon (CBS 122620) and X. polymorpha (MUCL 49884). Ex-type strains are in bold and black.
