Neoasbolisia phylicae Abdollahz. & Crous, sp. nov.
MycoBank number: MB 833169; Index Fungorum number: IF 833169; Facesoffungi number: FoF 11067; Fig. 18.
Etymology: Name reflects the host genus Phylica from which it was isolated.
Mycelium superficial or immersed, pale brown to brown, branched, consisting of smooth, thin-walled, septate hyphae, constricted at septa, with a mucilaginous outer wall layer. Pycnidia superficial or immersed, mostly globose or pyriform, brown to dark brown, intercalary, meristogenous in development, pseudoparenchymatous, thin-walled, 1– 2 cell layers of textura angularis, (63 –)80– 140(– 180) × (56–)70 – 100(– 148) μm (av. = 110 × 90 μm, n = 20). Ostiole absent or not well-developed, mostly releasing conidia by means of irregular rupture. Conidia hyaline, aseptate, oblong to ellipsoid, with minute guttules, smooth, thin-walled, (4.5 –)4.6 – 5.2(– 5.9) × (1.6 –)1.8 – 2(– 2.3) μm (av. = 5.2 × 2 μm, n = 50).
Culture characteristics: Colonies leathery, appressed, with fluffy aerial mycelium, edge sinuate, glaucous grey to olivaceous grey after 2 wk in the dark at 25 °C. Colonies reaching 14 mm diam on MEA after 2 wk in the dark at 25 °C.
Typus: UK, Inaccessible Island, on Phylica arborea, 30 Sep. 2011, P. Ryan (holotype CBS H-24299, culture ex-type CPC 19982 = CBS 146168).
