Pseudocyphellaria beccarii (Kremp.) D.J.Galloway
  Bull. Nat. Hist. Mus. Lond. (Bot.)24: 119 (1994); Sticta beccarii Kremp., Nuovo Giorn. Bot. Ital. 7: 11 (1875); Stictina beccarii (Kremp.) Müll.Arg., Flora 65: 301 (1882). T: Sarawak [Malaysia], O.Beccari, Lichenes Borneenses No. 121; lecto: M, fide D.J.Galloway, loc. cit.; isolecto: BM, M. For additional synonymy see Galloway (1994: 119).  
  Thallus irregularly spreading in entangled clones, loosely attached centrally, 8–15 (–25) cm wide; apices free, ascending. Lobes linear-elongate, dichotomously to irregularly branching, 1–5 (–8) cm long, 3–8 (–12) mm wide, discrete at margins, imbricate centrally; apices divergent, rounded or truncate or furcate; lobe margins entire, markedly thickened, ridged below and often conspicuously pseudocyphellate, very rarely with occasional small lobules developing. Upper surface dark grey-black or blue-black, suffused red-brown at apices when wet, pale glaucous buff or greyish when dry, conspicuously punctate-depressed or dimpled, irregular to undulate or wrinkled, coriaceous, glossy in parts, maculate, without isidia, pseudocyphellae or soredia. Medulla white. Photobiont Nostoc. Lower surface pale buff or whitish at margins, red-brown to black centrally or sometimes uniformly pale brown, irregularly wrinkled to ±bullate; tomentum in scattered thin patches centrally to densely and uniformly developed, pale buff or whitish to red-brown or blackened. Pseudocyphellae white, widely scattered to common and ±crowded, round to irregular, 0.1–1 (–1.5) mm diam., conical-verrucose; margins distinctly raised and sharply defined, concolorous with lower cortex; decorticate area plane to ±concave, usually sunk in thick tomentum. Apothecia marginal or submarginal, rarely laminal, sessile to subpedicellate, rounded to subirregular, 2–5 mm diam.; disc pale to dark red-brown to ±blackened, darker than margin, at first concave, becoming plane to subconvex, matt, smooth, epruinose; exciple coarsely verrucose-scabrid, obscuring disc when young, pale buff to brown. Ascospores 3-septate, fusiform, 33.5–42.5 (–44.5) × (6.5–) 8–11 μm, pale brown. CHEMISTRY: Tenuiorin, methyl gyrophorate, gyrophoric acid, 7β-acetoxyhopane-22-ol, hopane-7β,22-diol (trace) and hopane-15α,22-diol.
  Occurs in eastern Qld and eastern N.S.W. on shrubs, tree trunks, rocks and on litter in rainforest, from sea level to 1080 m. Widespread in the Palaeotropics from Madagascar to Fiji and Samoa.
