Odontura rhaphidospora (Rehm) Clem.

Syn.: Beloniella rhaphidospora (Rehm) E. Müll. & Défago, Belonium rhaphidosporum (Rehm) Sacc., Dermatella rhaphidospora (Rehm) Sacc., Leptorhaphis pyrenopezizoides Rehm nom. nud., Odontotrema rhaphidosporum (Rehm) Rehm, Odontotremella raphidospora (Rehm) Rehm, Pyrenopeziza rhaphidospora Rehm

Non- or doubtfully lichenised.

Substrate: lignum,

Altitudinal distribution: subalpine belt (potential vegetation: open, taiga-like forests dominated by Larix decidua and/or Pinus cembra and Rhododendron)

Note: a probably non-lichenised species with an endoxylic thallus and circular, dull black, deeply urceolate ascomata (to 0.5-0.8 mm in diam.) with a central, finally dentate pore and radially arranged furrows, a dark brown, 2-layered exciple lacking crystals, interascal filaments with capitate apical cells, functionally unitunicate, moderately polyspored asci, and filiform, fasciculate ascospores breaking up into 1-septate, fusiform part-spores (16-30 × 1.5-2.5 µm); on decorticated wood of conifers (e.g. Pinus cembra), from the boreal zone of Scandinavia to upper montane to subalpine forests, with a few records from the Austrian and Swiss Alps.
