Aqualignicola hyalina Ranghoo et al.
Index Fungorum number: 467769                                                         

 

Sexual morph: Ascomata 120–125 µm high, 140–150 µm diam, semi-immersed, membranous, hyaline to pale-brown, mostly gregarious. Neck 150–180 µm long, 35–40 µm diam, dark-brown, slightly curved, composed of setae. Setae lanceolate, stiff, dark-brown, surrounding the neck, 15–20 µm long, 5–10 µm wide. Peridium 22±5–27±5 µm wide, in surface view of textura angularis, composed of layers of light-brown pseudoparenchymatous cells. Paraphyses 95–100 ´ 3±75–5 µm, septate, flexuose, tapering towards the apex. Asci 137±5–150 ´ 9–12 µm, 8-spored, cylindrical, pedicellate, unitunicate, apically truncate, with a distinct cylindrical, J-, refractive apical ring, 3–3±5 µm high, 3±5–4 µm diam. Ascospores 14–15 ´ 6±25–7±5 µm, ellipsoidal, ellipsoidal-fusiform, uni-seriate to bi-seriate, ornamented under SEM, hyaline, unicellular, containing 2 large oil droplets, lacking a mucilaginous sheath or appendages. Asexual morph: Undetermined.

 

Specimen examined: CHINA, Hong Kong, New Territories, Tai Po, the Lam Tsuen River and Plover Cove Reservoir, on submerged wood (Ranghoo et al. 2001); INDIA, Western Ghats, Kali River, submerged woody litter (Sudheep and Sridhar 2011).
