Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig 1

Classification: Helminthosphaeriaceae, Sordariales, Sordariomycetidae, Sordariomycetes, Pezizomycotina, Ascomycota, Fungi

Helminthosphaeria was included in Melanosporaceae, in Sordariales based on its 1- septate ascospores with apical pores (Parguey-Leduc 1960). Lundqvist (1972) excluded Helminthosphaeria from Melanosporaceae due to its distinct filamentous pseudoparaphyses and asci lacking sheaths. Barr (1990b) reevaluated Sordariaceae and included Helminthosphaeria. Eriksson & Hawksworth (1993) placed Helminthosphaeria in Sordariales. Samuels et al. (1997) monographed the genus, including the asexual morph Diplococcium, and introduced Helminthosphaeriaceae (Goh & Hyde 1998, Réblová 1999a, Hernández-Restrepo et al. 2017).

Type species: Helminthosphaeria clavariarum (Desm.) Fuckel

Other accepted species: Species Fungorum – search Helminthosphaeria.
