Unveiling Sordariomycetes taxa associated with woody litter in Northern Thailand.

ABSTRACT: Sordariomycetes species are abundant in woody litter samples. In this study, we introduce two novel species, Diaporthethailandica (Diaporthaceae) and Occultithecachiangraiensis (Xylariaceae), from woody litter materials. We also describe a new host record of D.tulliensis and a new geographical record for D.melonis. All collections were identified based on morphology and phylogenetic analyses of combined datasets. The morphologies of the taxa fit the generic concepts of Diaporthe and Occultitheca, respectively. Diaporthethailandica formed a sister clade with D.raonikayaporum but differs from D.raonikayaporum in the sizes of conidiomata, conidiogenous cells, and beta conidia. Diaporthethailandica also differs from D.rao
