Corynespora aquatica R.F. Castañeda, Heredia & R.M. Arias
Index Fungorum number: 488446; Mycobank number: 488446
Etymology: Latin, aquaticus refers to its growing in water
Sexual morph: Undetermined. Asexual morph: Colonies on the natural substrate effuse, hairy, amphigenous, brown; mycelium mostly immersed composed of septate, branched, smooth-walled, 1.5-2.5 diam., pale brown to brown hyphae. Conidiophores differentiated, mononematous, erect, straight, rarely flexuous, slightly clavate towards the apex, 1- to 4-septate, smooth-walled, brown, 49–68 × 3–4 µm; arising from a radially lobed basal cell. Conidiogenous cells unilocal, tretic, terminal, brown, 7–12 × 3–3.5 µm, mostly determinate, but sometimes with an enteroblastic, percurrent proliferation. Conidiogenous loci an apical pore. Conidial secession schizolytic. Conidia obclavate to cylindrical, solitary. acrogenous, (1–to) 2- (to 3-) distoseptate, 34–46 × 3.0–4.5 µm, pale brown, smooth-walled, dry.
