Data Set Maintenance: Data set compiled (Flora of Australia Vol. 55 Lichens-Lecanorales, Parmeliaceae). Data set author(s): Nöske, N. M. @EXCL@ Bungartz F. (06-05-11). Data set not revised; to be published after submission.

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

Type Information: Basionym: Xanthoparmelia iniquita Elix & J. Johnst. Type: Xanthoparmelia iniquita Elix & J. Johnst.; type specimen label data: J. A. Elix 4781; holo: CBG.

Taxonomic Literature: Bull. Brit. Mus. (Nat. Hist.), Bot. 15: 270 (1986).

Biogeography: Southern hemispheric; upper montane (upland areas with moderate rainfall). Continent: Australasia. Checklist records: Australia (rarely collected endemic species; southeastern Australia: N.S.W., A.C.T. and Vic.).

Ecology: Lichenized; saxicolous.

Thallus: Foliose, irregular, lobed; lobes linear (irregular to linear-elongate), imbricate (moderately to sparingly imbricate); plane; separate thallus parts 2-3-(5) mm wide. Thallus Size and Differentiation: 6-8 cm in diameter; apex rounded (and crenulate). Upper Surface: Lime green (darkening), matt or glossy (shiny) (slightly shiny); fissurate (becoming cracked); immaculate; wrinkled (becoming rugose); not isidate; not sorediate; lobulate (occasionally developing narrower (0.8-1.5 mm) subdichotomously branched laciniae). Lower Surface: Present, pale brown (pale ivory to tan, darker towards lobe apices); attached by holdfasts (loosely to moderately adnate); rhizinate; rhizines moderately abundant or abundant, pale brown (concolorous with lower surface), not branched or branched (very rarely sparingly branched).

Medulla: White.

Reproduction Strategy: With sexual (and possible asexual) stages. Ascocarps: Apothecioid (scattered), soon sessile, up to 8 mm in diam.. Margin: Persistent, indistinct to distinct (thalline exciple thick and involute, becoming thin). Disk: Excavate (then undulate-distorted), brown or dark brown.

Ascospores: 8-9 µm long, 5-5.5 µm wide.

Conidiomata: Present (common).

Conidia: Bifusiform; 5-6 µm long; .5 µm wide.

Secondary Metabolites: Present; fumarprotocetraric acid, protocetraric acid (and succinprotocetraric acid), and usnic acid.

Spot Tests: Cortex: KC – medulla: K + orange or + bluish red (pale brown), C –, PD + orange (orange-red).

UV-Fluorescence: Upper thallus surface – (negative).
