dorisauae

Sexual morph Ascomata 148–213 μm high, 240–347 μm diam. (x̄= 174 × 277 μm, n=4), immersed, subglobose to ellipsoidal in side-view, solitary to gregarious, coriaceous, brown to black, papillate. Necks short, 44–55 μm long, 80–109 μm diam. (x̄=48 × 99 μm, n=4), cylindrical, brown to black. Periphyses not observed. Peridium 13–24 μm (x̄=19 μm, n=4), equal in thickness, comprising one stratum of multilayers (over five layers) of brown cells of textura angularis with large lumina. Paraphyses 74 × 9 μm. Asci 41–51 × 16 μm (x̄=44 × 16 μm, n=4), 8-spored, unitunicate, thin-walled, clavate, pedunculated. Ascospores 8–13 × 5–7 μm (x̄=11 × 6 μm, n=35), biseriate, overlapping, unicellular, broadly ellipsoidal with one half broader than the other, with longitudinal wall striations, guttulate, appendaged. Appendages at one end of ascospores, five to seven in number, crown-like, sheet-like irregular and radiating, delicate and subgelatinous. Asexual morph Undetermined.
