Data Set Maintenance: Data set compiled (Flora of Australia Vol. 55 Lichens-Lecanorales, Parmeliaceae). Data set author(s): Nöske, N. M. @EXCL@ Clerc, P. (04-11-02). Data set not revised; to be published after submission.

Nomenclature: Current taxonomic status: basionymous. Taxonomic rank: species. Currently accepted name Xanthoparmelia examplaris Elix & J. Johnst. Xanthoparmelia. Parmeliaceae Zenker (1827); Lecanorineae; Lecanorales.

Type Information: Basionym: Xanthoparmelia examplaris Elix & J. Johnst. Type: Xanthoparmelia examplaris Elix & J. Johnst.

Biogeography: Southern hemispheric (endemic, very rare, known only from the type collection). Continent: Australasia. Checklist records: Australia.

Thallus: Foliose, subdivided into main parts, irregular, lobed; lobes linear (sublinear), imbricate (or not); branches applanate (moderately flattened); separate thallus parts.7-1.5-(3) mm wide. Thallus Size and Differentiation: Up to 5 cm in diameter. Upper Surface: Yellow (pale yellow to yellow-green, lobe margins often blackened at margins), matt; fissurate (irregularly cracked); immaculate; wrinkled (lobes becoming distinctly rugulose and markedly areolate); not isidate; not sorediate; lobulate (laciniae subascending). Lower Surface: Present, yellow (straw-yellow to pale tan, often darkening to grey-black towards lobe apices); attached by holdfasts (adnate); rhizinate; rhizines sparse, brown, not branched.

Reproduction Strategy: With sexual (and possible asexual) stages. Ascocarps: Apothecioid (subpedicellate), 1-4 mm in diam.. Margin: Crenulate (becoming thinner, crenulate to deeply incised), smooth, distinct (thick, entire, involute). Disk: Urceolate (then +/- flat), brown (dark brown).

Secondary Metabolites: Present; throughout the thallus medulla, consalazinic acid, protocetraric acid (+/- traces), salazinic acid, and usnic acid.

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