Nomenclature

Family: PyronemataceaeGenus: Octosporopsis
SUMMARY
Anamorph: not known.
Teleomorph: stromata absent. Ascomata apothecia, 2-7 mm diam., sessile, at first cupulate and later becoming discoid, at first pale yellow to pinkish orange, becoming yellow-orange to bright orange when fully mature. Margin at first extending beyond the disc, later inconspicuous, the outer surface of the entire ascoma covered in thick-walled glassy hyaline hairs 100-300 (-400) x 6.5-13 µm in size, with the medulla composed of thin-walled hyaline ± hyphal cells and an outer layer of thick-walled hyaline globose to angular cells. Interascal tissue of unbranched filiform paraphyses, 4-6.5 µm diam., slightly swollen in the apical region (to 9.5-14 µm diam. when living), the contents hyaline to pale yellow. Asci 240-280 (-300) x 28-36 µm, often narrower in dead material, narrowly clavate with a long tapering basal region below the ascospores, croziers present, operculate, not staining in iodine, 8-spored. Ascospores unseriate to biseriate, (26-) 27-39 (-41) x (12-) 15-19 (-20.5) µm, ellipsoidal to ellipsoid-fusiform, hyaline, thin-walled at maturity, becoming thicker-walled when over-mature, usually binucleate, when living filled with minute light brown refractive droplets.
