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>本数据集为柔膜菌目（Helotiales）的初步比对拼接型ITS+LSU核糖体DNA（rDNA）数据集。其分类采样覆盖25个科：蛛盘菌科（Arachnopezizaceae）、卡氏盘菌科（Calloriaceae）、厚顶盘菌科（Cenangiaceae）、毛盘菌科（Chaetomellaceae）、绿杯盘菌科（Chlorociboriaceae）、科迪尔盘菌科（Cordieritidaceae）、皮盘菌科（Dermateaceae）、镰孢盘菌科（Drepanopezizaceae）、胶盘菌科（Gelatinodiscaceae）、戈氏盘菌科（Godroniaceae）、柔膜菌科（Helotiaceae）、异球腔菌科（Heterosphaeriaceae）、透明盘菌科（Hyaloscyphaceae）、毛杯菌科（Lachnaceae）、细齿盘菌科（Leptodontidiaceae）、洛氏盘菌科（Loramycetaceae）、米氏盘菌科（Mitrulaceae）、软盘菌科（Mollisiaceae）、碗菌科（Pezizellaceae）、普氏盘菌科（Ploettnerulaceae）、勒氏盘菌科（Roesleriaceae）、鲁氏盘菌科（Rutstroemiaceae）、核盘菌科（Sclerotiniaceae）、颤盘菌科（Vibrisseaceae），以及若干分类地位尚未明确的类群。 —— <i>Annabella australiensis</i> gen. & sp. nov.（柔膜菌目，科迪尔盘菌科）：产自澳大利亚南部红树林的新属新种 作者：Sally C.
