| Lichenes Rar. Crit. Exsicc. (Tokyo) No. 74 (1969). Based on Parmelia tenuirima f. corallina Müll.Arg., Flora 66: 46 (1883). T: Mitchell River, Gippsland, Vic., C.Ross s.n.; lecto: G; isolecto: PC, fide D.J.Galloway & J.A.Elix, New Zealand J. Bot. 21: 401 (1983). | ||
| Thallus loosely adnate to adnate, to 8–20 cm wide. Lobes imbricate, subirregular, apically rotund, short, 2–8 mm wide. Upper surface pale greenish grey to pale grey, flat, shiny, white-reticulate becoming conspicuously cracked and pseudocyphellate; pseudocyphellae effigurate, somewhat raised, dense, fusing into a reticulate network over the entire surface; dactyls (pustular isidia) developing from pseudocyphellae, erumpent apically; soredia derived from cracks or dactyls, coarse and becoming corticate in part, forming dense laminal and rarely marginal soralia and/or extended, granular, coralloid-isidioid outgrowths. Lower surface moderately densely rhizinate; rhizines simple or squarrosely branched, 1–2 mm long. Apothecia rare, pedicellate, 5–15 mm wide; disc concave, then flattening and splitting radially; thalline exciple reticulately cracked, pseudocyphellate, sorediate. Ascospores 10–12 × 6–8 µm. Pycnidia scattered. Conidia bacilliform to weakly bifusiform, 5–7 × 1 µm. CHEMISTRY: cortex K+ yellow; medulla K+ yellow then dark red, C-, P+ red-orange; containing atranorin, chloroatranorin, salazinic acid (major), consalazinic acid (minor), lobaric acid (minor) and ±protocetraric acid (trace). | ||
| A very common species in southern Australia (W.A., S.A., Qld, N.S.W., A.C.T., Vic. and Tas.); also on Norfolk Is. and Lord Howe Is. In the coastal forests of eastern Australia and Tas., this species is generally epiphytic on trees and shrubs in undisturbed forests or scrub habitats, whereas in the drier inland areas of W.A., S.A., N.S.W. and Vic., moist, shaded rock is the most common habitat. It also occurs in South Africa, India, Indonesia, Taiwan, Japan and New Zealand. | ||
