Type species – Appendispora frondicola K.D. Hyde, Sydowia 46(1): 30 (1994).
Notes – Hyde (1994a) introduced a monotypic genus Appendispora to accommodate A. frondicola which was collected from dead rachis of Oncosperma horridum in Brunei. The genus is characterized by subglobose or irregularly, multi-loculate ascostromata, immersed in darkened pseudoclypeus, with minute ostiolar canel, cracked through host surface, 8-spored, fissitunicate, cylindrical, pedunculate, fissitunicate, with an ocular chamber and faint ring, embedded in hyaline, trabeculate pseudoparaphyses and brown, fusiform, 1-septate ascospores, with an irregular ridged ornamentation and narrow appendages at each end (Hyde 1994a, Ariyawansa et al. 2014b). Hyde (1994a) treated the genus in Didymosphaeriaceae and this was followed from many subsequent authors (Lumbsch & Huhndorf 2010, Zhang et al. 2012b, Hyde et al. 2013). Ariyawansa et al. (2014) re-circumscribed the genus and treated Appendispora in Roussoellaceae due to its morphological characteristics fits well with the familial concept of Roussoellaceae. Many subsequent authors followed Ariyawansa et al. (2014b)’s treatment (Dai et al. 2017, Wijayawadene et al. 2017a, 2018, 2020, Jiang et al. 2019). However, phylogenetic affinity of the genus is unresolved due to the lack of molecular data for the generic type.
