Brief description
Characterised by the large thallus; large, discrete pseudocyphellae (as in N. tenuirima); the coarse, irregularly inflated isidia; and salazinic acid in the medulla.
Distribution
North Island: Northland (Pandora) to Wellington. South Island: Nelson. Chatham Islands: (Awatotara Stream). Apparently endemic; still very poorly collected and obviously rare.
Habitat
Mainly coastal and lowland on Dacrycarpus dacrydioides, fenceposts, and rarely on rocks or soil.
Detailed description
Thallus orbicular, closely attached, 7-17 cm diam., corticolous. Lobes moderately to relatively broad, 4-8(-20) mm wide, apices subrotund, margins entire, ± sinuous. Upper surface smooth, shining towards margins, pale grey to dark brownish-grey, pseudocyphellae laminal, moderate, small, punctiform or curved, developing from elevated maculae, isidiate. Isidia developing directly from the upper cortex or along the edges of pseudocyphellae and cracks, delicate, cylindrical, ± richly branched and occasionally forming a dense mat over the surface of older lobes. Lower surface black or dark brown, paler at margins, moderately rhizinate with a pale marginal zone devoid of rhizines and papillae. Rhizines black, simple or sparingly branched. Apothecia occasional to rare, sessile, to 10 mm diam., disc concave to plane, dark brown, matt or slightly shining, margins thin, concave to plane, dark brown, matt or slightly shining, margins thin, crenate, isidiate or not. Ascospores ellipsoid, 14-18 × 7-9 µm.
Chemistry: Cortex K+ yellow; medulla K+ yellow→red, C−, KC+ red, Pd+ orange; containing atranorin and salazinic acid.
