One of the 100 most parsimonious trees inferred from a heuristic search of ITS nrDNA sequences of Astraeus spp. Clades I–III and subclades 1–9 as mentioned in the text. Numbers separated by “/” represent maximum parsimony bootstrap values (BS) and Bayesian posterior probabilities values (PP), respectively. Percentage of bootstrap values < 50% and Bayesian posterior probability values < 0.5 are not included. Sequences from new specimens included in this study are marked and sequences from type specimens designated here are in bold. (*) before accession numbers from Phosri et al. (2007), indicates that SEM spores and basidiomes are illustrated in Figs 2 and 3.
