Linocarpaceae S. Konta & K.D. Hyde, Mycosphere 8(10): 1962 (2017)
Index Fungorum number: IF 553959; MycoBank number: MB 553959; Facesoffungi number: FoF 03843; 56 species.
Saprobic and endophytic fungi on monocotyledons and rarely dicotyledons. Sexual morph: Ascomata solitary, superficial, comprising black, dome–shaped (Linocarpon), slightly raised or flattened circular areas, or immersed (Neolinocarpon) 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 genus – Linocarpon Syd. & P. Syd.
Notes – A recent treatment and updated account of Linocarpaceae by Konta et al. (2017) placed this family in Chaetosphaeriales, which was confirmed by Hyde et al. (2019a). The first record of appressorium structures was from Neolinocarpon (Hyde et al. 2019a).
