title: A combined ITS rDNA and beta-tubulin phylogeny of Thai species of Hypocrella with non-fragmenting ascospores.
abstract: A combined ITS and beta-tubulin gene phylogeny has revealed new species of Hypocrella and Aschersonia related to the type species Hypocrella discoidea from natural forest in Thailand. As a result, Hypocrella calendulina and Hypocrella luteola are named as new species with Aschersonia sensu stricto anamorphs for specimens previously identified as Hypocrella discoidea sensu Petch. Hypocrella siamensis and Aschersonia minutispora are described as new species, both exhibiting brown stromata, with the former producing whole ascospores.
