Classification: Incertae sedis, Sordariales, Sordariomycetidae, Sordariomycetes, Pezizomycotina, Ascomycota, Fungi

Saprobic on palm fronds or wood. Sexual morph: Ascomata cleistothecial, solitary, superficial, membranaceous, globose, dark brown to black. Peridium composed of brown to hyaline cells of textura angularis to textura prismatica. Paraphyses numerous, filamentous, branched, embedded in a gelatinous matrix. Asci 8-spored, unitunicate, cylindrical to subclavate, pedicellate, apex rounded and thick-walled. Ascospores uni-seriate, limoniform to oval, hyaline to brown to dark brown when mature, wall minutely verrucose, aseptate, guttulate, surrounded by inconspicuous hyaline mucilaginous sheath. Asexual morph: Undetermined (adapted from Hyde 1994; Raja and Shearer 2008).

Notes: Lockerbia palmicola was introduced as generic type, and is similar to Diplogelasinospora, Neurospora and Sordaria species in having ellipsoidal ascospores with slightly irregular verrucose wall and surrounded by a hyaline mucilaginous sheath (Hyde 1994; Raja and Shearer 2008). Hence, Lockerbia was considered as a member in Sordariales genera incertae sedis (Maharachchikumbura et al. 2016; Hyde et al. 2020).

Type species: Lockerbia palmicola K.D. Hyde, Sydowia 46(1): 24 (1994).

Other accepted species: Species Fungorum – search Lockerbia.
