Classification: Boliniaceae, Boliniales, Sordariomycetidae, Sordariomycetes, Pezizomycotina, Ascomycota, Fungi
Saprobic on decorticated wood. Sexual morph: Ascostromata superficial, irregular in shape, membranaceous, brown to black, glabrous, with fascicular arrangement, necks rostrate. Ascomata perithecial, subglobose, dark brown to black, ostiolate, with papilla, periphysate. Peridium composed of brown to dark brown cells of textura angularis. Paraphyses numerous, septate, unbranched, filiform, guttulate, evanescent. Asci 8-spored, unitunicate, cylindrical, pedicellate, apex rounded, with J- inconspicuous apical ring. Ascospores uniseriate, subglobose to ellipsoidal, aseptate, hyaline, smooth-walled, with 2 guttules, without gelatinous appendages. Asexual morph: Undetermined (adapted from Huhndorf et al. 2005).
Notes: The monotypic genus Cornipulvina is characterized by ascostromata with long rostrate necks and ellipsoidal to subglobose ascospores without germ pores (Huhndorf et al. 2005). Sequence data from Cornipulvina ellipsoides (SMH 1378) is basal to Apiorhynchostoma and Pseudovalsaria in Boliniaceae (Huhndorf et al. 2005; 70%ML).
Type species: Cornipulvina ellipsoides Huhndorf, A.N. Mill., F.A. Fernández & Lodge, Fungal Diversity 20: 63 (2005).
Other accepted species: Species Fungorum – search Cornipulvina.
