Phylogenetic position of Achnanthidium gladius Ind391 (indicated in bold) based on Bayesian inference for the partial 18S rDNA gene. Total length of the alignment is 441 characters. Bootstrap supports from ML (constructed by RaxML) are presented above the horizontal lines (slash). Posterior probabilities from BI (constructed by Beast) are presented below the horizontal lines (slash). Only BS and PP above 50 and 0.9 are shown. All sequences have strain numbers (if available) and GenBank numbers.
