Trichoderma britdaniae  

Anamorph: not known.
Teleomorph: stromata large, undulate, up to ca. 10 cm long and 3 mm thick when fresh, often fragmenting into smaller parts. Stromata hard when dry, variably lobed or undulate, lobes 1.5–7 mm diam, 0.5–1 mm thick; narrowly attached. Surface smooth, distinctly folded or rugose when immature, covered by a farinose to floccose layer; ostioles small but distinct, flat to distinctly convex, dark brown. Stroma surface light to medium brown. Ascomata perithecia, 200–250 µm high, 80–125 µm diam., cylindric-ellipsoidal to subglobose. Peridium 15–25 µm thick at the base, 8–15 µm at the sides, yellow-brown. Ostiolar canal cylindrical, 50-70 µm long, 15–30 µm diam. Interascal tissue absent, at least at maturity. Asci 48-60 x 4–4.5 µm, cylindrical, short-stalked, thin-walled, the apex truncate, slightly thickened, with a thin J- apical ring. Ascospores arranged uniseriately, 1-septate but fragmenting into part-spores 2–2.5 (–3) x 2–2.5 µm in size, usually ± equal in shape and size, globose to subglobose, rarely ellipsoidal, smooth to finely spinulose, at first hyaline, yellow to pale orange when old.
