Ascomycota, genera incertae sedis

Parasitic on the host plant in terrestrial habitat. Sexual morph: undetermined. Asexual morph: Conidiomata dark brown, caulicolous or foliicolous, sporodochial or acervular, solitary to gregarious or often confluent, immersed or superficial, thick-walled. Conidiomatal wall composed of textura angularis with dark brown, thick-walled cells. Conidiophores arising from basal layers of stroma, pale brown at the base, becoming much paler towards the apex, cylindrical to subulate, parallel, unbranched, septate, thick- and smooth-walled. Conidiogenous cells pale brown, annellidic, cylindrical, integrated, terminal, smooth-walled, with 18 percurrent proliferation. Conidia hyaline, falcate to fusiform or cylindrical, with obtuse apex and truncate base, straight or gently and irregularly curved, 1-septate, smooth-walled, guttulate.

Type species: Anaphysmene heraclei (Lib.) Bubák, Annls mycol. 4(2): 124 (1906)

Notes: Anaphysmene shares similar conidia with Ascochytopsis and Pseudoseptoria and for differences among these genera see notes of Ascochytopsis. Sutton (1972a) re-described the genus and listed the synonyms. Sutton & Hodges (1990) described a second species A. cupressi from needles of Cupressus lusitanica, which is distinguished by its sporodochial conidiomata and 1014-septate conidia. No molecular data is available for Anaphysmene species.

Distribution: France, Germany (Sutton 1980).
