Index Fungorum number: IF 276675; Facesoffungi number: FoF 06250
Saprobic and parasitic on leaves of Rollandia racemosa. Sexual morph: Mycelium perisporioid, hyaline, filiform. Ascomata 46–59 µm × 60–83 µm (x̅ = 61.6 × 70 µm, n = 10), solitary, or in small groups, superficial, globular, amber-colored to dark brown, gelatinous, ostiolate, setae absent. Peridium 20.9–25.6 µm, thin, carbonaceous or membranaceous, 2–3 layered, composed of dark brown cells of textura angularis. Hamathecium of dense asci, lacking pseudoparaphyses. Asci 31–44 µm × 11–13 µm (x̅ = 36.8 × 12.3 µm, n = 10), 8-spored, bitunicate, fissitunicate, broadly clavate, with a short pedicel. Ascospores 19–28 µm × 7–9 µm (x̅ = 24.3 × 8.2 µm, n = 10), oblong to ellipsoid, hyaline when young, turning reddish brown at maturity, 4-celled, slightly constricted at the septum, with hyaline at two end cells. Asexual morph: Undetermined.
Material examined – USA, Oahu, Hawaii, Honolulu, Waiahole Ditch Trail, on leaves of Rollandia racemosa (Campanulaceae), 12 June 1921, F.L. Stevens (BISH 499971, isotype).
Economic significance – The fungus in the genus Limaciniopsis is associated with filamentous blue-green algae and is a parasitic fungus on the mycelium (Stevens 1922, Clements 1931).
