Parasitic on the host plant. The sexual morph is undetermined. The asexual morph is characterised by immersed or superficial conidiomata, which are acervulus or sporodochial, dark brown and separate to aggregated or often confluent. The conidiomatal wall is composed of thick-walled, dark brown cells of textura angularis. Conidiophores are formed from the upper cells of the conidiomata wall, which are erect, cylindrical to subulate, unbranched, thick- and smooth-walled, and the base is pale brown, becoming paler towards the apex. Conidiogenous cells are integrated, annellidic, cylindrical, terminal, and with pale brown smooth wall. Conidia are hyaline, thin- and smooth-walled, 1-euseptate, guttulate or eguttulate, falcate to fusiform or cylindrical, straight or gently and irregularly curved, with truncate base and obtuse apex (Sutton 1980, Sutton and Hodges 1990, Li et al. 2020).
Notes: Anaphysmene was introduced by Bubák (1906) based on A. heraclei as the type species. Sutton (1972) redescribed this genus and listed its synonyms. The conidia of Anaphysmene are similar to Ascochytopsis and Pseudoseptoria, which are hyaline and fusiform to falcate conidia. Anaphysmene was separated from Pseudoseptoria and Ascochytopsis by its acervulus conidiomata and 0–1-septate conidia (Sutton 1980). Sutton and Hodges (1990) described A. cupressi as the second species which have sporodochial conidiomata and 10–14-septate conidia. Currently, there are two species listed in Anaphysmene in Species Fungorum (May, 2024). However, no sequence data are available for these species in GenBank (May, 2024). The updated taxonomic treatment of this genus is genera incertae sedis, in Ascomycota (Wijayawardene et al. 2022).
