Figure. Evolutionary relationships of Acanthobasidium, Aleurodiscus (s.s.) and Neoaleurodiscus The evolutionary history was inferred using the UPGMA method [1]. The optimal tree with the sum of branch length = 0.27259509 is shown. The percentage of replicate trees in which the associated taxa clustered together in the bootstrap test (1000 replicates) are shown next to the branches. (Only Bootstrap values more than 50% are shown) [2]. The tree is drawn to scale, with branch lengths in the same units as those of the evolutionary distances used to infer the phylogenetic tree. The evolutionary distances were computed using the Kimura 2-parameter method [3] and are in the units of the number of base substitutions per site. The analysis involved 19 nucleotide sequences. All positions with less than 95% site coverage were eliminated. That is, fewer than 5% alignment gaps, missing data, and ambiguous bases were allowed at any position. There were a total of 812 positions in the final dataset. Evolutionary analyses were conducted in MEGA6 [4].

For all taxa the GenBank number of the DNA-sequence is shown. For the tree, the same sequences are used, which Sheng-Hua Wu used for his most parsimonious tree. [5]
