Siphulella coralloidea Kantvilas, Elix & P.James
  Bryologist 95: 186 (1992). T: Rasselas Track, 2 km north-west of Florentine Bridge, Tas., 42°42'S, 146°23'E, 4 Oct. 1986, G.Kantvilas & J.Jarman 165/86; holo: HO; iso: BM n.v., CANB.  
  Primary thallus crustose, pale brown to bright greenish yellow, glossy, thin to verruculose, ecorticate, evanescent. Podetia erect, pendant to ascending to decumbent, terete, subterete or ±flattened (especially basal sections of repeatedly branched podetia), simple to branched, discrete or rarely fusing, corticate, white to ash grey to bluish grey to pinkish buff on storage; surface matt to rarely glossy, pitted and undulate, mostly areolate and scabrid; apices rounded and slightly swollen, with or without aborted apothecia or galls; galls pale to dark grey, rarely pale pink, discrete and subglobose to clustered and cerebriform, 1.5–3 mm wide. Stipes irregularly corticate; cortex patchily developed or absent in young podetia; fertile stipes robust, simple to coralloid, ±weakly furrowed or striate. Apothecia rare, broad and weakly convex to strongly capitate, hemispherical to subglobose, sometimes with sunken areas, 1–3.5 mm wide, solitary or rarely 2 per podetium, held above vegetative thallus; disc pale to bright pink, scabrid to almost cerebriform. Ascospores ellipsoidal to oval-ellipsoidal, (9.5–) 10.5–17 (–19.5) × (3.5–) 4–6 (–7) µm; damaged or aborting spores with thickened apices, usually more ovoid than healthy spores. Pycnidia not seen. CHEMISTRY: Cortex and medulla K–, C–, KC–, P+ yellow; containing siphulellic acid; unknown yellow pigment in primary crust.
  Endemic to higher rainfall areas of south-western Tas.; grows on steeply sloping banks of coarse wet well-drained soils, or on peat or small stones. Most common in subalpine to alpine heathland and buttongrass moorland, rarely in wet scrub or low eucalypt woodland. Frequently a primary coloniser of roadside cuttings.
