Xanthoparmelia squamariatella (Elix) O.Blanco, A.Crespo, Elix, D.Hawksw. & Lumbsch
  Taxon 53: 971 (2004); Neofuscelia squamariatella Elix, Mycotaxon 71: 448 (1999). T: Australia. Australian Capital Territory: Brindabella Range, summit of Mt. Aggie, 43 km WSW of Canberra, 35°28'S, 148°46'E, 1490 m, on exposed schist rock, J. A. Elix 11640 & P. W. James, 21.i.1984; holo: CANB; iso: HO.  
  Thallus subcrustose, very tightly adnate, saxicolous, 1-6 cm wide.  Lobes contiguous to slightly imbricate, flat, irregular, short to sublinear, 0.3-0.8(-1.0) mm wide.  Upper surface yellowish brown to reddish brown, paler at the lobe apices, dull, or slightly shiny at the lobe apices, smooth, becoming fissured and areolate in thallus centre, lacking soredia and isidia.  Medulla white.  Lower surface dull, not or only obscurely rhizinate, pale tan to brown; lower cortex in part agglutinated directly to substratum.  Apothecia common, ±immersed when young, becoming sessile or subimmersed, to 0.8 mm wide; disc ±flat, dark brown; thalline exciple entire.  Ascospores globose to ellipsoidal, 5-7 x 3.5-5.5 µm.  Pycnidia common.  Conidia  bacilliform, 5-6 x 1 µm. CHEMISTRY: Cortex K-, HNO3+ dark blue-green; medulla K+ yellow then red, C-, P+ orange-yellow; containing norstictic acid (major), connorstictic acid (minor), hyposalazinic acid (minor).
