Abstract

In a comprehensive survey of fungi conducted in the northern (Chiang Rai Province) and southern (Narathiwat Province) regions of Thailand, several xylariales-like specimens were discovered. Through the integration of molecular phylogeny and morphological analyses, one previously undocumented taxon,Oxydothis narathiwatensissp. nov., was identified, along withXylaria bawanglingensisandHypoxylon hypomiltumas new host and geographical records fromAfzelia xylocarpa, andDalbergia cana, respectively. In addition,Annulohypoxylon thailandicumwas identified as a new host record fromSwietenia macrophyllain Thailand. The morphological characters, including ascomata, asci, and ascospores, were compared with knownOxydothis,Xylaria,Hypoxylon, andAnnulohypoxylonspecies. Multi-locus phylogenetic analyses based on ITS, LSU, and SSU (for Oxydothidaceae), ITS,rpb2,tub2, andact(for Xylariaceae), and ITS, LSU,rpb2, andtub2(for Hypoxylaceae) gene regions were carried out to refine the taxonomic classifications of these specimens further. This research contributes to understanding fungal diversity in these ecologically significant regions, highlighting insights into the relationships among xylariales-like species.
