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.

Abstract

A new genus of helotialean fungi, Annabella gen. nov. (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.
