LEAF SPOTS at first olive green, later brown, with a narrow, red margin, subcircular to prolate, 2-10 mm diam, confluent with time.

PYCNIDIA (p) crowded on the lesions, immersed or slightly erumpent, subepidermal, unilocular, globose to subglobose, sometimes slightly flattened, 60-125 µm diam, yellow to dark brown, with a subcircular to elliptical ostiolum, 20-35 µm diam.

Wall (w) 5-7.5 µm thick, composed of thick-walled, yellow to brown, angular cells.

Conidiogenous cells (cc) phialidic, hyaline, sessile on the inner wall surface of pycnidia.

CONIDIA (c) hyaline, filiform, usually slightly curved, 2-4- septate, 25-50 x 1.5-2 µm.

PLANT HOST AND DISTRIBUTION. The plant host of the S. oenotheare specimens presented here was Oenothera biennis L. s.s. growing in Szczecin (53º26'N, 14º35'E; Adamska, pers. observ.). Other reports of the occurrence of S. oenotherae in Poland are those of Dominik (1963), Madej (1963), Mulenko (1989), and Wroblewski (1914). Kruszynski (1934) found this fungus near Lida (53o53', 25o18'E; Lithuania).
