Parasitic on the host plant. The sexual morph is undetermined. The asexual morph is characterised by the immersed pycnidial conidiomata, which are black, glabrous, solitary to aggregated or confluent, thick-walled, unilocular and ostiolate. The ostiole is short, circular to oval and located in the center. The pycnidial wall is comprised of textura globulosa to textura prismatica, thick-walled and brown to hyaline cells. Conidiophores are reduced to conidiogenous cells. Conidiogenous cells are enteroblastic and phialidic, ampulliform to subcylindrical, smooth and hyaline. Conidia are hyaline, guttulate, smooth, obclavate, 0–1-septate, apex attenuated and base narrow and truncate, with a cup-like or irregular, and mucoid at the base and appendage at apex (Boedijn 1951, Li et al. 2020).

Notes: Groveolopsis was introduced by Boedijn (1951) based on G. pandani as the type species. Subsequently, Li et al. (2020) considered one collection as G. pandani based on morphology and ITS sequence data. Based on the NCBI GenBank, the ITS of Li et al. (2020) collection showed the highest similarity to Acrocalymma spp. However, Groveolopsis has obclavate, 0–1-septate conidia, which differs from cylindrical to fusoid and 0–3-septate conidia in Acrocalymma (Trakunyingcharoen et al. 2014). Therefore, Li et al. (2020) regarded G. pandani as a generic taxon in Acrocalymmaceae (Pleosporales). Wijayawardene et al. (2022) estimated that there were six species in Groveolopsis without providing any species names. Species Fungorum (September 2024) lists one species in Groveolopsis. There is one ITS sequence data available for Groveolopsis in GenBank (September 2024). The updated taxonomic treatment of this genus is Acrocalymmaceae, in Pleosporales (Dothideomycetes) (Wijayawardene et al. 2022).
