  in J.D.Hooker, Fl. Tasman. 2: 351 (1860); Tubercularia heteromorpha (Nyl. ex C.Bab. & Mitten) Kuntze, Revis. Gen. Pl. 2: 877 (1891). T: Tas., "supra terram argillaceum", R.C.Gunn; lecto: BM n.v.; isolecto: H-NYL 40290 n.v., fide D.J.Galloway, Bot. Notiser 133: 80 (1980). ****Baeomyces fuscocarnea F.Wilson, J. Linn. Soc., Bot. 28: 371 (1891). T: Lilydale, Vic., F.R.M.Wilson 66, lecto: BM n.v., fide D.J.Galloway, loc. cit. ****[Baeomyces rufus auct. non (Huds.) Rebent.: R.B.Filson, Checklist Austral. Lichens & Allied Fungi 15 (1996)].  
  Primary thallus crustose to small-squamulose; squamules contiguous, crowded and overlapping, smooth to verruculose to cracked and ±areolate upon drying, with hyphae visible between areoles or scattered squamules at edge of thallus, dull to glossy, chalky white (rare) to pale to grey green or bright green, greener when moist, often buff to pale ochre to yellow ochre after long storage, spuriously maculate on verruculose specimens stained by clay, esorediate, with or without schizidia. Apothecia subsessile to short- or long-stipitate, biatorine, solitary and terminal to clustered (clusters to 5 mm wide) at tips of branched stipes to numerous and subsessile along length of ±unbranched stipes, (0.1–) 0.2–2 (–2.5) mm diam.; stipe terete (when immature) to irregularly laterally compressed, simple to branched, usually 3–7 (–10) mm long, variably lichenised; margin continuous with and concolorous with core of stipe, cream to buff, rarely pale pink, semi-translucent when wet, becoming minutely furrowed and subcrenulate or flexuose to undulate and recurved in large apothecia; disc plane to strongly convex and undulate-distorted with age, very rarely cerebriform, brownish pink to red-brown to fuscous brown, smooth to scabrid. Ascospores ellipsoidal to oval-ellipsoidal, (7–) 8.5–11 (–13.5) × (2.5–) 3–4 (–4.5) µm. Pycnidia not seen. CHEMISTRY: Thallus K+ yellow then deep red, P+ orange, UV–; containing norstictic acid (major), connorstictic acid (minor), subnorstictic acid (±trace), gyrophoric acid (±minor or trace, in apothecium), crustinic acid (±faint trace, in apothecium) and salazinic acid (±faint trace, very rare).
  Occurs in S.A., N.S.W., A.C.T., Vic. and Tas.; possibly on Heard Is. Widespread and often locally common in moist sites, in full sun to partial shade, on soils (often clay-rich), pebbles and gravels and associated bryophytes and litter, acidic and siliceous rocks, rare on charcoal; a primary coloniser of road cuttings, creek banks and root mounds of upturned trees, sometimes forming extensive mats. Also common and widespread in New Zealand, and reported from high altitudes in New Guinea.
