Neoantennariella phylicae Abdollahz. & Crous, sp. nov.
MycoBank number: MB 833167; Index Fungorum number: IF 833167; Facesoffungi number: FoF 11065; Fig. 17.
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 cylindrical, pale to dark brown, mostly intercalary, lateral or terminal on erect hyphal branches, meristogenous in development, pseudoparenchymatous, thin-walled, 1– 2 cell layers of textura angularis, (40 –)50– 65(– 85) × (30–)50 – 60(– 68) μm (av. = 45 × 42 μm, n = 20). Ostiole absent, or not well-developed, mostly releasing conidia by means of irregular rupture. Conidia hyaline, aseptate, ellipsoid to ovoid, with minute guttules, smooth, thin-walled, (3.9 –)4.5– 5.2(– 5.9) × 2.5 – 3.2(– 3.6) μm (av. = 4.8 × 2.9 μm, n = 50).
Culture characteristics: Colonies leathery, appressed, with fluffy aerial mycelium; surface folded, edge sinuate, smoke grey to glaucous grey after 2 wk in the dark at 25 °C. Colonies reaching 17 mm diam on MEA after 2 wk in the dark at 25 °C.
