Podospora fimiseda  

Anamorph: not known.
Teleomorph: ascomata perithecia, 450-700 µm diam. and 650-1100 µm tall, scattered or in clusters, superficial to partially immersed, ovoid to obpyriform, covered all over with rigid, straight or curved, nonagglutinated, usually unbranched, cylindrical or tapering, septate brown hairs, 20-120 µm long and ca 3.5 µm diam., with hyaline, obtuse, rarely even inflated or pointed tips. Neck cylindrical, 100-385 x 210-240 µm. Peridium pseudo-bombardioid, coriaceous, opaque, black-brown, 4-layered, with ± angular, partly thick-walled outer cells; gelatinized layer 15-20 µm thick below. Interascal tissue of filiform-ventricose paraphyses. Asci 400-420 x 55-60 µm, clavate, with a tapering, rounded to slightly truncate apex, with a thin apical ring 5-6 µm diam. and ca 1 µm thick, 8-spored. Ascospores biseriately arranged, at first hyaline, one-celled, cylindrical to somewhat dumb-bell-shaped, then clavate, swelling above, transversely uniseptate. Upper cell 48-60 x 27-31 µm, ellipsoidal, slightly inequilateral, ranging through ochraceous, olivaceous to blackish brown, with an apical germ pore. Lower cell 36-44 µm long, 7-8.5 µm broad at the end, 4.5-5 µm broad just below the septum, obclavate, often distally cylindrical, collapsing. Gelatinous appendages at each end of the spore, tapering, rounded in cross-section, seemingly striate owing to perforation in the centre by many narrow, longitudinal canals, persistent, not swelling in water, blackening in Indian ink; upper appendage 85-180 x 13-17 µm, not covering the germ pore, subapically placed on the flattened side of the spore, lower appendage 80-155 x 10-12 µm, attached to the end of the lower cell.
