N: (Northland to Wellington). S: Nelson to Southland. Throughout, coastal and inland on bark of introduced, deciduous trees (Acer, Populus, Quercus, Salix, Ulmus etc) in urban, agricultural and often polluted environments; occasionally on leaves of ferns, trees, shrubs, hedges and garden plants (e.g. Hepatica) where it appears to be fast-growing and of relatively short duration. Also common on specimen trees of native species (Griselina, Hoheria, etc) in urban parks and gardens with some degree of atmospheric pollution. Green (1997) has measured growth rates of 0.72–2.95 mm per 100 days for this lichen when growing on leaves of citrus (orange and lemon) and Camellia in a study made in Hamilton gardens. Known also from Great Britain, Europe, Scandinavia, East Africa, South Africa, North and South America and Australia (Swinscow & Krog 1988; Purvis et al. 1992; Moberg 2002e, 2004b; Becker 2002; McCarthy 2003c, 2006; Nimis & Martellos 2003; Santesson et al. 2004).

Hyperphyscia adglutinata is characterised by: the corticolous habit; the agglutinate, thin, very closely attached small, greenish brown thallus; narrow, flat lobes with truncate to slightly broadened apices; and orbicular, crateriform, erose, laminal soralia.
