Leptotrochila medicaginis (Fuckel) Schüepp, Phytopath. Z. 36: 253 (1959)

= Sporonema phacidioides Desm., Annls Sci. Nat., Bot., sér. 3 8: 172, 182 (1847)


Saprobic or parasitic on the host plant in terrestrial habitat, such as Medicago sativa, M. lupulina (Fabaceae). Sexual morph: see Sutton (1980) and Semeniuk 1982). Asexual morph: Conidiomata up to 150 µm diam., 100 µm deep, brown, pycnidial, solitary to gregarious or confluent, immersed, subglobose, unilocular, convoluted, glabrous. Ostiole absent, dehiscence by breakdown of apical wall in the middle part. Conidiomatal wall composed of thick-walled, pale brown to hyaline, compact cells of textura angularis in the basal and lateral part, becoming dark brown, with larger cells towards the apex. Conidiophores arising from inner layers of the basal and lateral wall of conidiomata, hyaline, cylindrical or irregular, branched, septate, smooth-walled. Conidiogenous cells 7–15 × 2–3 µm hyaline, enteroblastic, phialidic, cylindrical to lageniform, integrated or discrete, indeterminate, smooth-walled, with periclinal thickening at collarette zone. Conidia 4–5.5 × 2–2.5 µm, hyaline, fusiform to cylindrical or irregular, unicellular, smooth-walled, eguttulate (adapted from Sutton 1980).
