Index Fungorum number: IF551485; Facesoffungi number: FoF00960 Fig. 1
Etymology – from the Latin lignin and cola, in reference to its habit on wood.
Holotype – MFLU 15-2717

Saprobic on the dead wood. Sexual morph: Ascomata 294 – 387 μm high (including neck), 187 – 225 μm diam., solitary to gregarious, scattered, immersed or erumpent, uni – loculate, subglobose to obpyriform, coriaceous, visible on host surface as raised, dark spots, with papillate ostiole. Ostiole central, with pore – like opening and papilla to long neck. Peridium 14 – 21 μm wide, of unequal thickness, slightly thin at the base, composed of several layers of brown to dark brown, thick-walled cells, arranged in a textura angularis. Hamathecium composed of 1 – 2 μm wide, filiform pseudoparaphyses, anastomosing between and above the asci, embedded in a gelatinous matrix . Asci ( 59.5 – ) 63 – 132(−137) × (9.5–) 10 – 12.5 (−13.5) μm (x̄ = 98.7 × 12.2 μm, n = 25), 8 – spored, bitunicate, fissitunicate, fusiform-clavate, with a long foot-like or knob – like pedicel, apically rounded, with a well – developed ocular chamber. Ascospores (18.5–) 19 – 21 (−22) ×( 4.9) – 5.2 – 6 (−6.3) μm (x̄ = 20.3 × 5.8 μm, n = 30), 1 – 3 overlapping seriate, hyaline, fusiform with narrow ends, 1 – septate, constricted at the septum, upper cell shorter and wider, lower cell long and narrow, slightly curved, surrounded by a mucilaginous sheath. Asexual morph: Undetermined.
