Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig 1

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

Saprobic on wood. Sexual morph: Ascomata perithecial, solitary or scattered, superficial, subglobose to ovoid, membranaceous, brown to black, with setae, ostiolate, with papilla, periphysate. Setae hyaline to brown, straight, rigid, with acute apex. Peridium composed of loose arrangement, of hyaline to brown cells of textura angularis to textura prismatica. Asci 8-spored, unitunicate, cylindrical to clavate, apex blunt, with J- apical ring, pedicellate. Ascospores cylindrical to allantoid, aseptate to multi-septate, hyaline to brown, smooth-walled or verrucose, ends rounded, slightly curved, guttulate. Asexual morph: Undetermined (adapted from Persoon 1796; Karsten 1873; Miller and Huhndorf 2004a).

Notes: Miller and Huhndorf (2004a) established Echinosphaeria for Lasiosphaeria canescens based on LSU sequence analysis. This genus clustered with Helminthosphaeria in Helminthosphaeriaceae (Hongsanan et al. 2017; Wijayawardene et al. 2018; Hyde et al. 2020). In this study, Echinosphaeria nests in Helminthosphaeriaceae based on the LSU-TUB sequence analysis.

Type species: Echinosphaeria canescens (Pers.) A.N. Mill. & Huhndorf, Mycol. Res. 108(1): 31 (2004).

Other accepted species: Species Fungorum – search Echinosphaeria.
