Classification: Nitschkiaceae, Coronophorales, Hypocreomycetidae, Sordariomycetes, Pezizomycotina, Ascomycota, Fungi

Saprobic on wood. Sexual morph: Ascomata solitary to gregarious, superficial, sitting on rarely developed subiculum, carbonaceous to coriaceous, brown to black, reniform to subglobose, collapsing or laterally collapsing when dry, lacking ostioles. Peridium composed of brown to hyaline cells of textura angularis to textura prismatica. Pseudoparaphyses numerous, septate, constricted at the septa, unbranched or branched, evanescent. Asci 8-spored, unitunicate, arising from a hyaline placenta-like tissue, radially extending into the locule from the base, broadly clavate, with long pedicel, evanescent. Ascospores hyaline when young, becoming pale brown to brown, broadly fusiform to ellipsoidal, with papillate at each end, 1-septate, smooth-walled, guttulate. Appendages initially mucilaginous sheath-like and encapsulate the whole ascospore, becoming fragment to give rise at each end and middle septum. Asexual morph: Undetermined (adapted from Koch et al. 1983).

Notes – The monotypic Groenhiella was introduced as a lignicolous marine fungus and initially placed in Coronophoraceae (Koch et al. 1983). It is characterized by black ascomata, clavate asci and 1-septate ascospores with fragmented sheath (Koch et al. 1983). Later, this genus was transferred as a member of Nitschkiaceae (Eriksson & Hawksworth 1987, Lumbsch & Huhndorf 2010, Maharachchikumbura et al. 2016, Hyde et al. 2020e, Index Fungorum 2021).

Type species: Groenhiella bivestia Jørg. Koch, E.B.G. Jones & S.T. Moss, Bot. Mar. 26(6): 265 (1983).

Other accepted species: Species Fungorum – search Groenhiella.
