Similar to Pannaria minutiphylla except in the following characters:
Soredia common, 6–12 mm diam., developed from the exposed medulla along margins or from cracks or eroded parts of the upper surface, almost approaching isidiomorphs, but cortex mostly incompletely developed. Apothecia scattered, laminal, substipitate, 7–25 mm diam.; disc rufous-brown, flat; thalline margin crenate-striate, with soredia. Proper ascospores hyaline, non-septate, ellipsoidal, sometimes weakly asymmetrical, 65–100 μm 13–18 mm; perispores ellipsoidal, sometimes asymmetrical, 65–100 μm 135– 200 mm, verruculose when immature, verrucae few and poorly developed when mature, with apical, pulvinate extensions present in most spores.
North Island: northern and southern regions. South Island: widespread. Also occurs on Stewart Island, the Auckland Islands, and Campbell Island.
In Australia it is common in Victoria and Tasmania. Also occurs in Argentina and Chile.
Common on tree trunks, and occasionally found on rocks. Phorophytes include the following species and genera: Aextoxicum punctatum*, Acacia*, Atherosperma moschatum*, Berberis*, Chiliotrichum*, Coprosma, Dracophyllum, Empetrum*, Encalyptus*, Eucryphia*, Drimys winteri*, Fuchsia excorticata and F. magellanica*, Halocarpus bidwillii, Hebe, Kunzea, Leptospermum, Lomatia*, Metrosideros, Myrsine, Fuscospora (eight species noted), Olearia, Ovidia pillo-pillo*, Pandorea*, Persea lingua*, Pilgerodendron uviferum*, Pittosporum, Podocarpus, Pomaderris, Prostanthera*, Saxegothaea conspicua*, Sophora, Trochocarpa*, Ugni molinae* and Weinmannia.
Also collected on leaves of Laureliopsis* and Knightia excelsa (with Pannaria phyllidiella), and in Tasmania it was locally common on fences. Altitudinal range from near sea level to 1370 m.
Chemistry: TLC: vicanicin (major), and 3 to 4 unidentified terpenoids (trace), 4- O’-methylvicanicin in some samples. HPLC: vicanicin (major),
Separated from Pannaria minutiphylla by the presence of soredia (and see Brief description above).
Corticolous. Occasionally foliicolous and on rocks.
