Figure. Buergenerula spartinae (NYBG986085). A–B. Ascomata. C–D. Asci. E–F. Ascospores. G. Hyphopodium. Scale bars: A = 200 µm; B = 50 µm; C–G = 10 µm.

Buergenerula spartinae Kohlm. & R.V. Gessner, Can. J. Bot. 54(15): 1764 (1976).
MycoBank: MB310003.

Ascomata perithecial, immersed, solitary or gregarious, dark brown to black, 200–450 µm diam, with a cylindrical, hyaline to brownish neck, 150–250 × 90–150 µm. Paraphyses hyaline, septate, dissolving at maturity. Asci 8-spored, unitunicate, clavate, 100–165 × 15–20 µm, with a refractive ring. Ascospores biseriate in ascus, clavate, rounded at apex, narrowed toward base, straight or slightly curved, 3-septate, not or slightly constricted at septum, hyaline to yellowish, smooth, 35–55 × 9–13 µm. On CMA with seawater, conidiophores branched, up to 20 µm long. Conidiogenous cells phialidic. Conidia curved, 5 × 2 µm (Asexual state description from Kohlmeyer and Gessner, 1976).
