Type genus.

Linocarpon Syd. & P. Syd.

Description.

Saprobic and endophytic fungi on monocotyledons and rarely dicotyledons. Sexual morph: Ascomata solitary or aggregated, superficial or immersed comprising black, dome-shaped or subglobose, slightly raised blistering areas with a central ostiole or immersed with a black shiny papilla. Peridium composed of dark brown to black cells of textura angularis. Hamathecium comprising septate paraphyses that are 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 or claviform, straight or curved, unicellular with or without refringent bands, with or without polar appendages. Asexual morph: Phialophora -like spp. were found in Linocarpon appendiculatum and L. elaeidis cultures ( Hyde 1992b), but no records are available for other species.

Notes.

Linocarpaceae was introduced as a new family to accommodate Linocarpon and Neolinocarpon species, based on morphology and phylogeny ( Konta et al. 2017). Appressoria were first recorded from Neolinocarpon rachidis ( Hyde et al. 2019). The new genus Claviformispora , which is well-supported within Linocarpaceae suggests that there is a need to amend the morphological circumscriptions of the family given that the ascomata (subglobose) and ascospore (claviform) characters are so different from the other two genera.
