Godronia uberiformis
Godronia uberiformis J.W. Groves, Can. J. Bot. 43: 1245 (1965)
= Topospora uberiformis (Kunze) Fr., Summa veg. Scand., Sectio Post. 69: 415 (1849) [1848].
Saprobic or parasitic on the host plant. Sexual morph: see Groves (1965). Asexual morph: Conidiomata up to 800 µm wide, 1350 µm high, dark brown to black, pycnidial, solitary to gregarious, at first immersed, eventually erumpent and appearing superficial, globose to oval or obpyriform, unilocular, glabrous, ostiolate. Ostiole single, circular, papillate, centrally located. Conidiomatal wall composed of thick-walled, dark brown to black cells of textura oblita in the exterior, becoming thin-walled, subhyaline to hyaline cells of textura angularis towards hymenium. Conidiophores up to 35 µm long, 2.5–3 µm wide, arising from the inner layers of basal wall and part way up the sides of the conidiomata, hyaline, cylindrical, branched at the base and above, septate, smooth-walled. Conidiogenous cells hyaline, enteroblastic, phialidic, subcylindrical to lageniform, integrated or discrete, determinate, smooth-walled, with prominent collarettes. Conidia 17–22.5 × 3–3.5 µm, hyaline, cylindrical to fusiform, with obtuse apex and narrow and truncate base, 3-septate, smooth-walled, eguttulate (Sutton 1980, Nag Raj and DiCosmo 1981).
