Morpho-molecular diversity of Linocarpaceae (Chaetosphaeriales): Claviformispora gen. nov. from decaying branches of Phyllostachys heteroclada

Abstract

In this paper, Claviformisporagen. nov. in Linocarpaceae is introduced from Phyllostachys heteroclada in Sichuan Province, China. The new genus is characterised by its distinct morphological characters, such as ostiole with periphyses, asci with a thick doughnut-shaped, J- apical ring and clavate ascospore without septum-like band and appendage. Maximum Likelihood and Bayesian Inference phylogenetic analyses, based on DNA sequence data from ITS, LSU, SSU and TEF-1α regions, provide further evidence that the fungus is a distinct genus within this family. The new genus is compared with similar genera, such as Linocarpon and Neolinocarpon. Descriptions, illustrations and notes are provided for the new taxon.

Morpho-Molecular Characterization of Microfungi Associated with Phyllostachys (Poaceae) in Sichuan, China

“…Datasets were aligned using MAFFT v.7.407 [ 37 ], and ambiguous regions were excluded with BioEdit version 7.0.5.3 [ 38 ]. Maximum likelihood (ML) and Bayesian inference (BI) were constructed as described in Xu et al [ 39 ]. The phylogram was visualized with FigureTree v. 1.4.3 and edited using Adobe Illustrator CS6 (Adobe Systems Inc., San Jose, CA, USA).…”
