ITS+LSU sequence dataset of Helotiales

This is a crude aligned and concatenated ITS+LSU rDNA dataset of Helotiales. Taxonomic sampling covers 25 families (Arachnopezizaceae, Calloriaceae, Cenangiaceae, Chaetomellaceae, Chlorociboriaceae, Cordieritidaceae, Dermateaceae, Drepanopezizaceae, Gelatinodiscaceae, Godroniaceae, Helotiaceae, Heterosphaeriaceae, Hyaloscyphaceae, Lachnaceae, Leptodontidiaceae, Loramycetaceae, Mitrulaceae, Mollisiaceae, Pezizellaceae, Ploettnerulaceae, Roesleriaceae, Rutstroemiaceae, Sclerotiniaceae, Vibrisseaceae) and a number of taxa without clear affinities.<br>--<br> <i>Annabella australiensis</i> gen. &amp; sp. nov.

(Cordieritidaceae), is described to accommodate <i>Annabella australiensis </i>sp. nov. This species was collected on attached decaying wood of <i>Avicennia marina</i>, a common mangrove species found in protected waters of southern Australia. <i>Annabella</i> 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 <i>Annabella</i> is most similar to <i>Skyttea</i>. The molecular phylogenetic analysis of a concatenated dataset of three ribosomal nuclear loci confirms the placement of <i>Annabella</i> within Cordieritidaceae, as a sister clade to <i>Skyttea</i>. <br>
