Brief description
Characterised by the corticolous habit; the pale greenish white or olivaceous, wrinkled-tuberculate, granular-verrucose or glebose thallus; sessile to subpedicellate, brown-black to red-brown apothecia; a massive yellow-brown hypothecium (200–350 μm thick); and filiform, acicular, 8–16-septate ascospores, 45–70(–90) × 1.5–3.5(–4) μm.
Distribution
North Island. South Island: Throughout.
Known also from Great Britain, Europe, Scandinavia.
Habitat
On Cordyline, Griselinia, Hoheria and other trees, forming mosaics on smooth bark, delimited by a narrow, irregular prothallus. Often among epiphytic mosses and ferns and often overgrowing these, lowland and coastal.
Detailed description
Thallus pale greenish-white or olivaceous, shining in parts, becoming wrinkled-tuberculate, granular-verrucose or glebose, continuous, or in scattered colonies or ± squamulose, in patches 2-5(-10) cm diam. Apothecia prominent, solitary, 0.1-2.5 mm diam., round to irregular, brown-black or brownish-red, sessile to subpedicellate, plane or concave at first, margins entire, ± flexuose, disappearing with age, disc convex at maturity, matt, epruinose. Epithecium granular, red-brown to black, 5-13 µm thick. Hymenium colourless or pale brownish 65-90(-100) µm tall. Paraphyses dense, thin, apices clavate, red-brown to black. Hypothecium massive, yellow-brown, 200-350 µm thick. Ascospores filiform, acicular, 8-16-septate, 46-68(-90) × 1.7-3.4(-4) µm.
