Description:
Saprobic on host. Sexual morph: Ascomata 230–310 μm diam., 200–400 μm high, rounded, apothecioid, immersed to erumpent-superficial, dull black with protruding cells or hyphae. Peridium 50–70 μm soft, pseudoparenchymatous, comprising dark reddish-brown cells of textura angularis. Pseudoparaphyses 2.2–2.5 μm narrow cellular, bluntly rounded, encrusted with reddish brown pigment. Asci 80–100 × 30–40 μm (x̄ = 85.2 × 35.2 µm, n = 10), bitunicate, oblong clavate to cylindrical. Ascospores 10–13 × 3.5–4 μm (x̄ = 11.2 × 3.7 µm, n = 10), hyaline becoming light dull brown on maturity, obovoid oblong, ends obtuse, straight or inequilateral, 3−6(−7)-trans-septate, longitudinal septum in one or more cells, wall and septa thick, smooth with homogeneous contents and refractive or granular; overlapping 2-seriateor triseriate in the ascus. Asexual morph: Unknown.
Material examined: Europe, on Salix species (Salicaceae), 5 June 1898, Feurich (F234831).
