Hyde et al. (2016) introduced Paracapsulospora to accommodate a single species P. metroxyli, which is saprobic on dead Metroxylon in Thailand. Phylogenetic analysis of the LSU sequence data showed that Paracapsulospora related to both Magnaporthales and Amplistromatales. Due to limited sequence data availability, Paracapsulospora has not been assigned to an order and is left in Sordariomycetes incertae sedis (Hyde et al. 2016). The sexual morph of the genus is characterized by solitary, immersed, uniloculate, globose to subglobose ascomata surrounded by a dark brown layer of peridium cells. The peridium consists of black, thick-walled cells with textura angularis in the outside and hyaline, thin-walled cells inside. Asci are 8-spored, unitunicate, cylindrical with a long pedicel. Oblong to cylindrical and hyaline ascospores are arranging uni-seriately. They are bi-guttulate and aseptate, with thin and smooth walls and appendages with a distinct mucilaginous sheath. The asexual morph remains undetermined.
Type species: Paracapsulospora metroxyli Konta & K.D. Hyde
