Anamorph: on 2% MEA with wheat straw, conidiomata formed as yellow to orange stromatic structures with convoluted locules. Conidiophores verticillately branched. Conidia 2.5-4 x 1-1.5 µm, ellipsoidal to fusiform-ellipsoidal, aseptate. Teleomorph: ascomata apothecia, to 3 mm diam., scattered or grouped, erumpent, short-stalked, initially closed and then ± globose, expanding to form a ± flat disc. Disc orange to orange-yellow, surrounded by persistent white to pale buff hairs. Hairs 4-5 µm diam., cylindrical, thin-walled, finely granular. Outer wall composed of globose to polygonal cells, with the central tissue composed of loosely interwoven hyphae. Interascal tissue of unbranched paraphyses, 50-70 x 1-1.5 µm, longer than the asci, flexuous, filiform, not swollen at the apices, containing yellow lipid bodies. Asci 45-60 x 4-5.5 µm, narrowly cylindrical to cylindric-clavate, the apex obtuse to rounded with a pore that usually stains blue in iodine, 8-spored. Ascospores arranged irregularly biseriately, 6-10 x 2-2.5 µm, narrowly ellipsoidal to cylindric-fusiform, hyaline, aseptate, without guttules, thin-walled, without a gelatinous sheath or appendages.
