Fibulocoela indica Nag Raj, Can. J. Bot. 56(13): 1491 (1978)
Facesoffungi number: FoF 07368
Foliicolous. Sexual morph: undetermined. Asexual morph: Conidiomata 120–300 diam., 100–240 µm high, stromatic, pycnidial, solitary to gregarious or confluent, subepidermal, deeply immersed in origin, later yellowish white conidial mass visible in surface view, globose to subglobose in section view, multilocular, gelatinous, glabrous, thick-walled, ostiolate. Ostiole single, oval to cylindrical, centrally located. Conidiomatal wall 10–15 µm wide, composed of an outer, hyaline, loose network of clamp-bearing hyphae, and an inner densely packed textura intricata to textura epidermoidea. Conidiophores arising from the innermost wall layers of conidiomata, hyaline, cylindrical to subcylindrical, sometimes broader at top, forming oval to rounded structure, branched or unbranched, septate with a clamp connection at each septum, smooth-walled, invested in a thin, non-persistent layer of mucus. Conidiogenous cells holoblastic, sympodial, hyaline, cylindrical to subcylindrical, terminal, later becoming lateral when arising from the clamp connections along the length of the conidiophores, smooth-walled. Conidia 13–19 × 1–3 µm ( x= 16 × 2 µm; n = 30), hyaline, cylindrical to subcylindrical, with rounded apex and slightly truncate base, straight or slightly curved, aseptate, smooth-walled, bearing a single, unbranched, attenuated, tubular, flexuous apical appendage (9–17 µm long); conidia extruded from conidiomata in long cirrhi.
