Descriptions
Chiodecton colensoi (A.Massal.) Müll.Arg.
Thallus in irregular patches 0.5-1-(-4) cm diam., pale brownish-white, grey-green or fawnish, minutely wrinkled-uneven, scabrid-granular, matt, continuous or minutely areolate-cracked, sometimes ± effuse or in parts lacking, delimited at margins by an irregular black prothallus. Apothecia in thalline verrucae, verrucae whitish or distinctly paler than thallus, raised, rounded to flexuose-elongate sigmoid, or ± confluent, 0.3-1.5 mm long and 0.1-0.4 mm wide, polycarpic, 1-6(-20) discs per verruca, disc minute, 0.05-0.15 mm diam., convex, plane or concave, black, carbonaceous or red-brown, rarely pale brown, shining or matt, aggregated or arranged in a row following shape of verruca. Ascospores 3-septate, acicular, flexuose, 46-56 × 3 µm. Hypothecium brown-black. Chemistry: TLC negative.
Thallus continuous, thin, greenish-olive to pale greyish-yellow or brownish, occasionally minutely areolate-cracked, in irregular patches, 1-3 cm diam., delimited by a thin black prothallus, corticolous. Apothecia lirelline, black, raised, straight or curved, or furcate-sigmoid, 0.1-0.8 mm long and 0.5 mm wide, often slightly covered with cortex, scattered rather widely. Asci clavate with a pronounced tapering foot and apical dimple. Ascospores narrow acicular, curved, to shallow sigmoid, 25-30(-40) × 1.8-2.5 µm. Chemistry: Thamnolic acid.
