Data Set Maintenance: Data set compiled (Flora of Australia Vol. 55 Lichens-Lecanorales, Parmeliaceae). Data set author(s): Nöske, N. M. @EXCL@ Bungartz F. (06-06-03). Data set not revised; to be published after submission.

Nomenclature: Current taxonomic status: accepted. Taxonomic rank: species. Currently accepted name Xanthoparmelia subpigmentosa Hale. Xanthoparmelia. Parmeliaceae Zenker (1827); Lecanorineae; Lecanorales.

Type Information: Basionym: Xanthoparmelia subpigmentosa Hale. Type: Xanthoparmelia subpigmentosa Hale; type specimen label data: L. Kofler 3669; holo: LD; iso: US.

Biogeography: Southern hemispheric; alpine. Continent: Africa (southern Africa) and Australasia. Checklist records: Australia (very rare, occurs in south-eastern Australia (N.S.W.)).

Ecology: Lichenized; saxicolous; growing sun-exposed, under conditions which are dry.

Thallus: Foliose, irregular, lobed; lobes imbricate (or not); plane; separate thallus parts 1-3 mm wide. Thallus Size and Differentiation: 4-6 cm in diameter; apex rounded (apices of marginal lobes subrotund). Upper Surface: Lime green, matt or glossy (shiny) (slightly shiny), smooth; immaculate; not isidate; not sorediate; lobulate (laciniae 0.7-1.5 mm wide). Lower Surface: Present, brown, pale brown, dark brown, or orange (occasionally orange); attached by holdfasts (loosely adnate to adnate); rhizinate (grouped subapically, 0.5-1.2 mm long); rhizines sparse or moderately abundant, pale brown (rarely partly brown-black, occasionally orange), not branched.

Reproduction Strategy: With sexual (and possible asexual) stages. Ascocarps: Apothecioid, soon sessile, 2-8 mm in diam.. Margin: Indistinct (involute at first, becoming deeply lacerate). Disk: Excavate (then undulate-distorted), brown (shiny) or dark brown.

Secondary Metabolites: Present; consalazinic acid (and skyrin (in the pigmented medulla)), salazinic acid, and usnic acid.

Spot Tests: Cortex: KC – medulla: K + yellow changing to red (pigmented medulla K+ violet), C –, PD + orange (intense orange).
