Podospora decipiens  

Anamorph: not known.
Teleomorph: stromata absent. Ascomata perithecia, 750-1000 x 600-750 µm, subglobose to conical or pyriform, very pale brown, semitransparent, membranous, covered with numerous hyphoid hairs, with a long, conical or subcylindrical blackish coriaceous tuberculate neck 125-300 x 125-170 µm in size. Peridium three-layered: 1) inner layer of pale thin-walled polygonal cells 10-27 µm diam., supporting abundant periphyses at the ostiole; 2) middle layer formed of ± cylindrical pale parallel thin-walled cells; 3) outer layer of very pale brown polygonal to epidermoid cells 8-12 µm diam., supporting numerous pale brown or hyaline septate hyphal hairs 2-3 µm diam. At the neck the outer wall cells are darker and covered with papillate protuberances, which are sparse at the base, but denser above, cylindric or clavate, blackish, wavy, thick-walled, 8-25 x 3-5 µm in size. Interascal tissue of ephemeral thin-walled cylindric-moniliform paraphyses 15-22 µm diam. at the base, tapering upwards. Asci 230-290 x 55-67 µm, clavate to saccate, quite long-stalked, somewhat pointed at the apex, lacking an apical ring, not staining in iodine, 8-spored. Spores biseriate or irregularly arranged, in the early stages cylindrical with an apical end tending to swell, transversely septate later. Spore head (33-) 35-42 x 19-23 (-25) µm, ellipsoidal, rarely slightly asymmetrical, smooth, thick-walled, with a subapical germ pore, often containing a de Bary bubble. Pedicel cylindrical, soon collapsing, straight or slightly curved, rounded or sometimes somewhat enlarged at the apex, 33-42 x 5.5-8 µm in size. Apical gelatinous appendage fan-shaped, densely and longitudinally fibrillose, 17-30 x (15-) 18-20 µm, arising from the apex of the spore head. Two basal gelatinous appendages arise from the pedicel near the spore septum: they are usually coiled, sometimes stretched and then narrower and longer than the apical appendage.
