Hyperphyscia adglutinata (Flörke) H.Mayrhofer & Poelt
Lecanora adglutinata Flörke, Dtsch. Lich. 4: 7 (1819).
Thallus small, orbicular, to 2 cm diam., thin and very closely attached to substrate, corticolous. Lobes narrow, to 0.5 mm wide, overlapping or distinctly separated. Upper surface brownish-grey or greyish-brown to dark brown, darker at lobe margins, sorediate. Soralia laminal, small, spot-like, usually abundant centrally. Lower surface hardly visible on account of the lobes being very closely attached to the substrate. Rhizines short, very sparse, indistinct. Apothecia rare, to 1 mm diam. Ascospores 1-septate, 13-18 × 7-10 µm. Pycnidia immersed. Conidia filiform 15-20 × 1 µm.
N: S: Throughout in urban areas on the bark of deciduous introduced trees (Acer, Pseudoplatanus, Quercus, Ulmus etc.) often in moderately polluted habitats. Ecology and distribution in New Zealand still very poorly know. It is doubtful whether this species is correctly placed in Hyperphyscia.
