Pseudocyphellaria prolificans (Nyl.) Vain.
  Philipp. J. Sci., Sect. C, Bot. 8: 117 (1913); Sticta prolificans Nyl., Ann. Sci. Nat. Bot., sér. 4, 15: 42 (1861). T: "ad cortices sylvarum in Kanala", New Caledonia, E.Vieillard 1795; holo: PC.  
  Thallus rosette-forming to irregularly spreading, often densely entangled, loosely to closely attached centrally, 5–12 (–15) cm wide. Lobes rather narrow, linear-laciniate (1–6 cm long and 2–5 mm wide) to ±rounded (8–15.5 mm wide), subdichotomously branching near apices, complex-imbricate centrally; apices truncate, rounded or divergent; lobe margins entire towards apices, becoming densely phyllidiate centrally, thickened above and below, often with prominent pseudocyphellae below. Upper surface pale greenish grey to fawnish when dry, lettuce-green to olive-green when wet, undulate, irregularly to strongly dimpled, punctate-impressed; without isidia, maculae, pseudocyphellae or soredia. Phyllidia common, mainly marginal but also laminal, terete, soon becoming flattened, dorsiventral, simple to branched, single to densely clustered and proliferating, to 5 (–10) mm tall, 0.1–0.5 mm wide. Medulla white. Photobiont green. Lower surface tomentose from margins to centre or only in older parts; tomentum whitish to pale yellow-brown or red-brown. Pseudocyphellae common, conspicuous, white, projecting from tomentum. Apothecia rare, marginal or submarginal, subpedicellate, 2–5.5 mm diam.; disc dark red-brown to chestnut-brown; exciple pale, corrugate-scabrid; epithecium pale yellow-brown; hymenium colourless. Ascospores fusiform-ellipsoidal, simple to 1-septate, 28–33.5 × 6.5–8 µm, yellow-brown. CHEMISTRY: Tenuiorin, methyl gyrophorate, gyrophoric acid, 4-O-methylgyrophoric acid (congyrophoric acid), 7β-acetoxyhopane-22-ol, hopane-7β,22-diol (trace) and hopane-15α,22-diol.
  Occurs in north-eastern Qld, on trunks and branches of trees and on shrubs and rocks in rainforest. Also in Lord Howe Is. and in the Palaeotropics from Sri Lanka to Fiji.
