Maximum likelihood tree based on partial gene sequences of β-tubulin and translation elongation factor 1-α (Scauflaire et al. 2011, De Vos et al. 2014). Sequence alignments were assembled with MAFFT version 7 (Katoh & Standley 2013). The program jModelTest v 2.1.7 (Guindon & Gascuel 2003, Darribo et al. 2012) was used to determine the best-fit substitution model (TIM2+I+G substitution model) with gamma correction (Tavare 1986). A maximum likelihood (ML) phylogenetic analysis was performed using PhyML v 3.1 (Guindon et al. 2010). Values at branch nodes are the bootstrapping confidence values with those ≥ 85 % shown. The F. circinatum FSP34 isolate used in this study is indicated in bold.
