Brief description
Characterised by the corticolous/lignicolous habit; the pustulate soredia arising mainly from the upper surface along coarse, blistery ridges; sparse marginal cilia; and lecanoric acid in the medulla.
Distribution
North Island: South Auckland (Glenbrook, Hamilton, Huntly, Te Kuiti). South Island: Canterbury (Christchurch, Banks Peninsula, Prices Valley, Springston, Rakaia River), Otago (Cameron Flat, Makarora, Dunedin), Southland (Queen’s Park Invercargill, Tiwai Point). Auckland Islands.
Known also from East and South Australia and from Chile.
Habitat
On bark of introduced and native trees and on decorticated wood (fenceposts, gates, railings), most commonly in urban and industrial habitats where it seems tolerant of moderate pollution.
Detailed description
Thallus closely attached, to 10 cm diam., corticolous or lignicolous. Lobes rounded, subirregular to 8 mm wide. Upper surface plane to wrinkled, faveolate, shining or rather waxy, greyish-fawn to greenish or buff, sorediate. Soralia laminal, rarely marginal, white or yellowish becoming grey-brown with age, originating from coarse, pustular ridges, becoming irregular-diffuse. Lower surface black, with a narrow, brown, naked marginal zone. Rhizines numerous, simple, black. Apothecia sessile, disc brown, thalline margin entire, sorediate. Ascospores 5-7 × 10-12 µm.
Chemistry: Cortex K+ yellow; medulla K−, C+ red, KC+ red, Pd−; containing atranorin, chloroatranorin and lecanoric acid (major).
