Wolfina aurantiopsis

Wolfina aurantiopsis (Ellis) Seaver ex Eckblad, Nytt. Mag. Bot., 15(1–2): 126 (1968)
Facesoffungi number: FoF 04207
Saprobic on soil. Sexual morph: Apothecia 2.5–4.5 cm diam., gregarious, sessile, superficial on the substrate. Receptacle cupulate, external surface rough, black, convoluted. Disc slightly concave, pale yellow to pale orangishochraceous. Hairs 5–12 µm diam., cylindrical, septate, brown, entirely covered by warts or prickles when immature, then smooth at the apices, while basal part remainornamented at maturity. Ectal excipulum composed of darker, septate cells of textura intricata, hyphae are perpendicular to the hyphae in medullary excipulum. Medullary excipulum composed of hyaline, septate cells of textura intricata. Subhymenium composed of cylindrical, septate cells of textura intricata. Paraphyses 3–4.5 µm wide, numerous, septate, filiform, slightly enlarged at the apices. Asci 340–430 x 14.5–20 µm, 8-spored, unitunicate, operculate, cylindrical, rounded at the apex, nonamyloid. Ascospores 25.4–32 x 10.4–15 µm, uniseriate, hyaline, ellipsoid, thick-walled, multi-guttulate, sometimes embedded in a gelatinous sheath, thin longitudinal, anastomosing striations present on the surfaces. Asexual morph: Undetermined (Description modified from Agnello et al. 2013).
Notes: Wolfina aurantiopsis is characterized and differs from other species in the genus by its larger ascospores with longitudinal striations (Agnello et al. 2013).
