Sordariomycetidae, Chaetosphaeriales, Linocarpaceae, Linocarpon
Index Fungorum number: IF2882; 43 morphological species (Species Fungorum 2020); 10 species and 9 unnamed species with sequence data.
Saprobic and endophytic fungi on monocotyledons and rarely dicotyledons. Sexual morph: Ascomata solitary, superficial, comprising black, dome shaped with a black shiny papilla. Peridium composed of dark brown to black cells of textura angularis. Paraphyses septate, longer than asci, wider at the base, tapering towards the apex. Asci 8-spored, unitunicate, cylindrical, with a J-, apical ring, developing from the base and periphery of the ascomata. Ascospores parallel or spiral in asci, hyaline or pale yellowish in mass, filiform, straight or curved, unicellular with refringent bands, with or without polar appendages. Asexual morph: A phialophora-like spp. was found in Linocarpon appendiculatum and L. elaeidis cultures (Hyde 1992a), but has not been recovered in other species (adapted from Konta et al. 2017).
Type species: Linocarpon pandani Syd. & P. Syd., Annls mycol. 15(3/4): 210 (1917)
Notes: Sydow & Sydow (1917) introduced Linocarpon and Hyde (1992) monographed the genus. The latter has since then been updated by Hyde (1997), Dulymamode et al. (1998), Hyde & Alias (1999), Fröhlich & Hyde (2000), Thongkantha et al. (2003), Cai et al. (2004), Konta et al. (2017) and Hyde et al. (2020). Ascospores of Linocarpon taxa usually comprise distinct appendages at their apex, an important feature distinguishing species within the same genus as well as from Leptosporella taxa (Poonyth et al. 2000, Yanna & Hyde 2003, Cai et al. 2004). The asexual morph of Linocarpon (phialophora-like) is seldom observed (Hyde et al. 1992).
