Liua muriformis Phookamsak & K.D. Hyde, in Phookamsak et al., Fungal Diversity: 10.1007/s13225-019-00421-w, [74] (2019)

Index Fungorum number: IF556176         Facesoffungi number: FoF05710

 

Sexual morph: Undetermined. Asexual morph: Coelomycetous. Conidiomata 80–150 μm high, 110–190 μm diam., pycnidial, scattered, solitary, immersed, slightly raised, visible as small black dot on host surface, uni-loculate, globose to subglobose, glabrous, dark brown to black, ostioles central, apapillate, with pore-like opening. Conidiomata walls 7–17 μm wide, thin-walled, of equal thickness, composed of 3–5 cell layers, of flattened, brown to dark brown, pseudoparenchymatous cells, arranged in a textura angularis to textura prismatica. Conidiophores reduced to conidiogenous cells. Conidiogenous cells (3–)5–12.5(–17.5) × (2–)5–10 μm l/w (x̅ = 8.2 × 5.4 μm, n = 30), holoblastic, phialidic, discrete, determinate, ampulliform to cylindrical, unbranched, aseptate, occasionally 1–2-septate, hyaline, smooth, arising from the inner cavity of the conidioma wall. Conidia (12.5–)13–15(–17) × 7–9(–10) μm l/w (x̅ = 14.4 × 8.2 μm, n = 50), phragmosporous to muriform, dark brown, oblong to ellipsoidal, or obovoid, (2–)3-transversely septate, with (0–)3 longitudinal septa, slightly constricted at the septa, smooth-walled.

 

Culture characteristics: Colonies on PDA, reaching 30–32 mm diam. after 3 weeks at room temperature (20–30 ºC). Colony dense, circular, flattened to slightly raised, surface rough, radially furrowed at the centre, smooth at the margin, with edge entire, velvety; from above, greyish green at the margin, pale yellowish to yellowish green at the centre; from below, dark green to greenish grey; not producing pigmentation on agar medium.
