Classification: Helminthosphaeriaceae, Sordariales, Sordariomycetidae, Sordariomycetes, Pezizomycotina, Ascomycota, Fungi
Saprobic on wood or leaves. Sexual morph: Ascomata perithecial, solitary or scattered, superficial, membranaceous, ovoid to obpyriform, brown to dark brown, tuberculate, covered with setae, ostiolate. Asci 8-spored, unitunicate, cylindrical. Ascospores biseriate, cylindrical, geniculate, one or both end(s) tapering to a distinct point or rounded ends, hyaline when young, becoming pale brown, smooth-walled, with guttules, 0–3-septate, sometimes with sheath. Asexual morph: Hyphomycetous. Conidiophores macronematous, mononematous, cylindrical, single or in group up to two, erect, arising directly from the host, multi-septate, cells expanding sometimes, brown to dark brown, apical cell swollen. Conidiogenous cells phialides, with cylindrical branches, hyaline to pale brown, discrete, smooth-walled; secondary branches, hyaline, 2–3 per branch, cylindrical, tapering at the apex. Conidia hyaline, aseptate, oblong to obovoid, smooth-walled (adapted from Fuckel 1870; Miller and Huhndorf 2004a).
Notes: Fuckel (1870) introduced Leptospora caudata has black ascomata and oblong ascospores and was accompanied with a hyphomycete with hyaline, oval conidia, on decayed wood of Betula alba in nature. This species was introduced as the generic type of Hilberina (Miller and Huhndorf 2004a). Subsequently, several taxa with bristly ascomata and ascospores distinctly curved or bent near the attenuate, lanceolate or acerose base were accepted as members of Hiberina (Declercq 2009, 2013; Miller et al. 2014). Miller et al. (2014) sequenced five Hilberina species and found that they are polyphyletic in Helminthosphaeriaceae and their asexual morphs are unknown. In this study, Hilberina species are closely related to members of Helminthosphaeria and scattered in Helminthosphaeriaceae. Its sexual-asexual link needs confirming with cultural characteristics and more phylogenetic data.
