Classification: Nitschkiaceae, Coronophorales, Hypocreomycetidae, Sordariomycetes, Pezizomycotina, Ascomycota, Fungi
Saprobic or parasitic on lichen. Sexual morph: Ascomata perithecial, gregarious, superficial, sitting on a subiculum composed of brown, septate hyphae, carbonaceous, turbinate, obovoid to subglobose, black, tuberculate, ostiolate, with periphyses. Peridium comprising black carbonaceous tissues at outer layer, inner layer composed of membranaceous, brown to hyaline cells of textura angularis to textura prismatica, Munk pores present. Paraphyses absent or cylindrical, septate, constricted at the septum. Asci 2-, 4- to 8-spored, unitunicate, clavate to cylindrical, apex rounded, apical ring inconspicuous, with long pedicel, evanescent. Ascospores uni- to bi-seriate, broadly fusiform, hyaline, aseptate when young, becoming brown to dark brown, 3-septate, rarely multi-septate, sometimes constricted at the septum, smooth-walled, guttulate. Asexual morph: Undetermined (adapted from Hawksworth 1980, Pérez-Ortega & Halici 2008).
Notes – Lasiosphaeriopsis, a lichenicolous genus, typified by L. salisburyi has tuberculate ascomata, clavate asci and broadly fusiform ascospores (Hawksworth 1980). Lasiosphaeriopsis species were reported on Amygdalaria, Peltigera, Pilophorus, Porpidia, Stereocaulon in America, Asia and Europe (Pérez-Ortega & Halici 2008). This genus was initially placed in Coronophorales (Hawksworth 1980), and subsequently assigned to Nitschkiaceae (Eriksson & Hawksworth 1987, Hyde et al. 2020e, Index Fungorum 2021).
Type species: Lasiosphaeriopsis salisburyi D. Hawksw. & Sivan., in Hawksworth, Trans. Br. mycol. Soc. 74(2): 373 (1980).
Other accepted species: Species Fungorum – search Lasiosphaeriopsis.
