Brief description
Characterised by the corticolous habit; fertile thalli with emaculate, sparsely ciliate lobes; the absence of isidia and soredia; and the presence of lecanoric acid in the medulla.
Distribution
North Island. South Island. Known also from Australia.
Habitat
A very common species on branches of trees and shrubs, rarely on rock. Occurs throughout cooler, higher rainfall areas of southern and eastern Australia (W.A., S.A., Qld, N.S.W., A.C.T., Vic. and Tas.); also on both islands of New Zealand (Anon. 2023).
Detailed description
Thallus closely attached, 2–4 cm diam. Lobes imbricate, sublinear–elongate, irregularly branched, generally narrow, 0.5–3 mm wide, margins sinuous, black-rimmed, glossy, cilia sparse, black 0.1–0.3 mm long. Upper surface pale-grey to grey-green, plane, glossy, emaculate, smooth or weakly faveolate at first becoming wrinkled, without isidia or soredia; often with granular, white pruina towards lobe apices. Lower surface black with a narrow, brown, glabrous marginal zone, rhizinate. Rhizines scattered to common, simple, black. Apothecia common, sessile to subpedicellate, 2–4 mm diam., disc concave, smooth, glossy, rarely sparsely pruinose (×10 lens), exciple smooth. Ascospores broadly ellipsoidal to subglobose, 9–13 × 7–9 μm. Pycnidia common. Conidia bacillar to weakly fusiform, 7–8 × 1 μm.
Chemistry: Cortex K+ yellow; medulla K−, C+ red, KC+ red; Pd−; containing atranorin, chloroatranorin, lecanoric acid (major) and occasionally orsellinic acid (tr).
Similar taxa
Similar to other Parmelioid lichens but distinguished by rhizines hairs and chemistry. Distinguished from other Parmelina species by its non-maculate upper surface.
Substrate
Corticolous
