Brief description
Lobes 0.3–1.2 mm wide; lobe apices epruinose; medulla C–; Isidia cylindrical; medulla PD+ yellow-orange.
Distribution
North Island: Northland (Radar Bush, Kataia, Whirinaki State Forest), Auckland, South Auckland (Pio Pio) to Wellington.
Habitat
On bark of Cordyline australis. Discovered in New Zealand by J. K. Bartlett (2.1.1980).
Detailed description
Thallus corticolous, adnate to loosely adnate, orbicular to spreading, 2–5 cm wide. Lobes linear, discrete or crowded, dichotomously to subdichotomously branched, 0.4–12 mm wide. Upper surface pale-grey to pale green-grey, white at the margins, convex, smooth, distinctly maculate (×10 lens), ±transversely cracked, isidiate. Isidia sparse to dense, cylindrical, simple, becoming coralloid branched. Medulla white, with a chondroid axis of parallel, longitudinally arranged hyphae in the centre of the lobes. Lower surface with continuous spongiostratum (spongy hypothallus) which often projects beyond the lobe margins, uniformly attached to lower medullary hyphae or chondroid axis, solid, dark-brown to black; rhizines scattered, simple or tufted. Apothecia and pycnidia not seen.
Chemistry: Cortex K+ yellow; Medulla K−, C−, Pd+ orange-red; containing atranorin (minor), chloroatranorin (minor), protocetraric acid (major) and virensic acid (tr.).
Similar taxa
Anzia entingiana differs from A. jamesii in having narrower, epruinose lobes, thinner, taller isidia and a different chemistry. A. entingiana is superficially similar to A. madagascariensis, but the latter species lacks isidia and has fumarprotocetraric acid as the major medullary compound (Elix 1997a). In earlier accounts, A. entingiana was erroneously included both as a fumarprotocetraric-acid-containing chemodeme of A. jamesii, and as the palaeotropical A. madagascariensis, which does not occur in New Zealand.
Substrate
