Figure: Molecular Phylogenetic analysis of Megalocystidium by the Maximum Likelihood method
The evolutionary history was inferred by using the Maximum Likelihood method based on the Kimura 2-parameter model [1]. The tree with the highest log likelihood (-4055.6447) is shown. The percentage of trees in which the associated taxa clustered together is shown next to the branches. A user-specified tree was used as an initial tree in the heuristic search. A discrete Gamma distribution was used to model evolutionary rate differences among sites (5 categories (+G, parameter = 1.0022)). The rate variation model allowed for some sites to be evolutionarily invariable ([+I], 71.5627% sites). The tree is drawn to scale, with branch lengths measured in the number of substitutions per site. The analysis involved 20 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 1158 positions in the final dataset. Evolutionary analyses were conducted in MEGA6 [2]

Figure: Evolutionary relationship of Megalocystidium
The evolutionary history was inferred using the Minimum Evolution method [1]. The optimal tree with the sum of branch length = 0.36807172 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 [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 ME tree was searched using the Close-Neighbor-Interchange (CNI) algorithm [4] at a search level of 2. The Neighbor-joining algorithm [5] was used to generate the initial tree. The analysis involved 20 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 Evolutionary analyses were conducted in MEGA6 [2]
