Differs from Belonopsis by superficial apothecia, which sometimes arise from dark-colored hyphal mass, observed as dark spots in superficial view, flattened in section (scutum, pl. scuta), wholly brownish receptacle, and the absence of crystals in the medullary excipulum. Differs from Trichobelonium in lacking crystals in the medullary excipulum and anchoring hyphae connecting the basal apothecia and subiculum. Differs from Mollisia by longer ascospores with (0 -) 1 - 3 septa, the color contrast between white hymenium and dark receptacle, and its preference for graminicolous habitats such as the culms of Sasa spp. and Miscanthus sinensis Andersson.	en	Itagaki, Hiyori, Hosoya, Tsuyoshi (2023): A new genus Neobelonopsis and two new species of Trichobelonium (Helotiales, Ascomycota) discovered mainly from poaceous grasses native to Asia in Japan.
