Maximum likelihood phylogeny of LipS: Instances of stwintron loss in Eurotiomycetes. A subtree of the phylogenetic analysis depicted in Fig. 3, is shown in detail to highlight the loss of the stwintron from taxa of Eurotiomycetes. Class-specific color coding is the same as in Fig. 3. Species that have lost the stwintron from their lipS gene have their name printed in red lettering. For the sake of simplicity, we have collapsed groups of related fungi that behave identically with respect to stwintron presence/absence. All the species in the collapsed clades for the Chaetothyriales order and the Penicillium genus have no intronic sequences at the stwintron position (second intron position in Aspergillus) and the taxon names are therefore marked with red boxes to highlight stwintron loss. Independent events of stwintron loss are also indicated by red triangles on the directly preceding branches (NB. The position of the triangles does not correspond with the exact time point at which stwintron loss has taken place)
