Based on the morphological and molecular discrepancies, Oberwinkler et al. (2014) found that Efibulobasidium rolleyi (= Exidia rolleyi) lacked the Chaetospermum conidial stage and was phylogenetically not closely related to the Chaetospermum clade, then transfer E. rolleyi into a new monotypic genus, Globulisebacina (Sebacinaceae), G. rolleyi as the type species. Efibulobasidium is considered a synonym for Chaetospermum (Oberwinkler et al. 2014). In 2017, the second species, G. chenii, was described from Taiwan Province (China) based on its placement in a molecular phylogeny of partial LSU rDNA sequences, and the morphology also conforms to the morphological concept of Globulisebacina (Kirschner et al. 2017). Later, another new combination, G. fulva, was introduced by Malysheva et al. (2019), as exidia fulva is very similar to or probably identical to the type species G. rolleyi. Globulisebacinas consists of three species and are classified as root endophytes. Globulisebacinas are pustulate or cupulate basidiomata, superficial, subglobose, gelatinous, solitary or gregarious, branched and septate hyphae and hyphidia, broadly ellipsoid to ovoid basidia with cylindrical or allantoid basidiospores, hyaline, and thin-walled (Kirschner et al. 2017, Malysheva et al. 2019).
