Pseudocyphellaria granulata (C.Bab.) Malme | ||
Bih. Kongl. Svenska Vetensk.-Akad. Handl. 25(3/6): 21 (1899); Sticta granulata C.Bab., in J.D.Hooker, Fl. Nov. Zel. 2: 281 (1855). T: Middle Island [South Island], New Zealand, D.Lyall; holo: BM. | ||
Thallus rosette-forming to irregularly spreading, loosely to closely attached, 5–10 (–20) cm wide. Lobes deeply incised, linear-elongate to broadly rounded, 1–5 cm long, 5–25 mm wide, discrete or contiguous at margins, imbricate centrally; lobe margins irregular, ragged, incised or crenulate, densely sorediate, often eroding white. Upper surface grey-fawn or glaucous yellowish when dry, glaucous green to olivaceous when wet, plane to subconvex, undulate, dimpled, punctate-impressed to faveolate in parts. Soredia in erose laminal or marginal soralia, coarsely granular, whitish to greenish black. Medulla white. Photobiont green. Lower surface pale at margins, black centrally, uniformly thickly tomentose or with a narrow glabrous marginal zone. Pseudocyphellae conspicuous, white. Apothecia rare, sessile to subpedicellate, marginal and laminal, to 1.5 mm diam.; disc matt black, white-pruinose at first; exciple pale buff to red-brown, roughened; epithecium smoky grey to olive-brown, K+ purple-violet; hymenium colourless, ±granular or with numerous oil droplets; hypothecium pale yellow-brown to straw-yellow, K–. Ascospores ellipsoidal, 1-septate, 22.5–32 × 9–11.5 µm, smoky grey to olive-brown. CHEMISTRY: Hopane-6α,7β,22-triol (major), 6α-acetoxyhopane-7β,22-diol (minor), hopane-15α,22-diol (trace) 7β-acetoxyhopane-6α,22-diol (trace), hopane-7β,22-diol (minor), 7β-acetoxyhopane-22-ol (trace), methyl virensate (trace), physciosporin (major), norstictic acid (trace), stictic acid (major), cryptostictic acid (trace) and constictic acid. | ||
Occurs in south-eastern Qld, eastern N.S.W., eastern Vic. and Tas.; occasional on living and dead wood, rocks (dolerite and sandstone) and tree stumps in ±open eucalypt forest and scrub. Also in New Zealand and its subantarctic islands, and southern South America. | ||
