ITS+LSU consensus tree of Helotiales

This is the consensus tree resulting from Maximum Likelihood inference of the ITS+LSU sequence dataset of Helotiales carried out using IQ-tree under partitioned models (GTR+I+G for ITS, TIM3+I+G for LSU) and ultrafast bootstrapping with 1000 replicates. --Annabella australiensis gen. & sp. nov. (Helotiales, Cordieritidaceae) from South Australian mangroves Authors: Sally C. Fryar1, Danny Haelewaters2,3 and David E.A.

(Cordieritidaceae), is described to accommodate Annabella australiensis sp. nov. This species was collected on attached decaying wood of Avicennia marina, a common mangrove species found in protected waters of southern Australia. Annabella is distinctive among Cordieritidaceae in having relatively small perithecioid, hyaline to yellowish apothecia and by the absence of an ionomidotic reaction. The apothecial shape and size of Annabella is most similar to Skyttea. The molecular phylogenetic analysis of a concatenated dataset of three ribosomal nuclear loci confirms the placement of Annabella within Cordieritidaceae, as a sister clade to Skyttea.
