摘要：In this study,a novel coniothyrium-like genus Coniothyrioides is introduced to Coniothyriaceae based on a fresh fungal collection from salt marsh habitats in Thailand.Coniothyrium-like taxa are taxonomically controversial and have been classified into different families in Pleosporales such as Didymosphaeriaceae(Alloconiothyrium and Paraconiothyrium),Coniothyriaceae(Coniothyrium)and Didymellaceae(Microsphaeropsis).However our novel genus shares similar morphology to some key characters in Coniothyriaceae in having dark,globose pycnidia,uni-locular conidiomata,a central ostiole,a peridium of textura angularis cells,and doliiform conidiogenous cells with a periclinal thickening at the apex,while conidial morphologies are diverse.The presence of setae arising from the outer peridial wall is the main difference between Coniothyrioides and other closely related Coniothyriaceae genera.Phylogenetically,LSU-SSU-ITS sequence analyses confirm the placement of this novel genus as a distinct lineage within Coniothyriaceae.Species boundaries were defined,based on morphology and multi-gene phylogenetic analyses using maximum likelihood and Bayesian inference analyses.The comprehensive descriptions and micrographs are provided.Our findings expand the taxonomic knowledge of Ascomycota in salt marsh ecosystems.
