Endococcus fusiger  

Anamorph: not known.
Teleomorph: stromata absent. Ascomata perithecia, 160-230 µm diam., scattered or in small clusters, subglobose, erumpent through the host thallus and becoming almost superficial, with an inconspicuous non-papillate ostiole, black. Peridium leathery to carbonaceous, comprising 3-6 layers of radially compressed thick-walled dark brown angular cells 4-5 µm in diam. Interascal tissue absent, the ostiole lined internally with periphyses. Asci in a basal fascicle, forming in a gelatinized matrix, 55-65 x 14-18 µm [measured in water],  clavate to cylindric-clavate, with a markedly thickened apex when young, not staining in iodine, 8-spored. Ascospores biseriately arranged, 12-15 x 6-7.5 µm, ellipsoidal to fusiform-ellipsoidal, the apex and base obtuse, hardly constricted at the single ± median septum, dark brown, smooth- and thick-walled, without a gelatinous sheath or appendages.
