Fibulocoela indica

Fibulocoela indica Nag Raj, Can. J. Bot. 56(13): 1491 (1978)

Facesoffungi number: FoF 07368

 

Foliicolous. Sexual morph: undetermined. Asexual morph: Conidiomata 120300 diam., 100240 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 1015 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 × 13 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 (917 µm long); conidia extruded from conidiomata in long cirrhi.
