Bunodophoron pinnatum Wedin  

Mycobank MB 517739

Thallus elongated, narrow, up to 7 cm long. Fertile branches narrowly flattened to almost terete, 30–50 mm long and 1–2 mm wide; major branch sparingly branched but typically with abundant, perpendicular, terete branchlets along the sides. Upper surface pale grey to white, smooth or rugose to slightly wrinkled above the apothecia. Lower surface white. Ascomata sparse, terminal, 2–4 mm wide. Mazaedia subapically exposed; thalline receptacle ruptured early but remaining and slightly widening at maturity. Ascospores ± globose, 6.5–7.5 µm in diam., greyish brown, with an irregular ornamentation of mazaedial material. Pycnidia common, along the sides and in the apices of terminal branchlets. Conidia oblong to obovoid, (3.0–)3.5–4.5 x 1.5 µm. Secondary chemistry: sphaerophorin and protocetraric acid (no ascomata were tested due to the scarce material).
