Xanthoparmelia condaminensis Elix & J. Johnst.

Data Set Maintenance: Data set compiled (Flora of Australia Vol. 55 Lichens-Lecanorales, Parmeliaceae). Data set author(s): Nöske, N. M. @EXCL@ Clerc, P. (04-10-18). Data set not revised; to be published after submission.

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

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

Taxonomic Literature: Mycotaxon 29: 363 (1987).

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

Ecology: Biotroph; lichenized; terricolous (grows on soil or debris).

Thallus: Foliose, subdivided into main (often entangled, weakly convolute) parts, isotomic-dichotomous (subdichotomously branched), lobed; lobes elongate, imbricate; separate thallus parts 1-3 mm wide. Thallus Size and Differentiation: Up to 10 cm in diameter. Thallus Outline: Irregular (forming irregular subpulvinate patches or rosettes) or orbicular. Upper Surface: Lime green (pale yellow-green), convex, matt, smooth (smooth to slightly rugulose); immaculate; not isidate; not sorediate; lobulate (margins sparsely lobulate, c. 0,5 mm wide). Lower Surface: Present, brown (pale tan to light brown, lobe apices darker); attached by holdfasts (loosely adnate); rhizinate (robust, tufted or not); rhizines sparse (very sparse), brown (concolorous with with lower surface), not branched.

Medulla: White.

Reproduction Strategy: With sexual (and possible asexual) stages. Ascocarps: Apothecioid (subpedicellate), sparse, 1-3 mm in diam.. Margin: Smooth, distinct (thick, entire). Disk: Excavate (weakly concave), brown (dark brown).

Ascospores: 7-9 µm long, 4-5 µm wide.

Conidiomata: Present.

Conidia: Bifusiform; 4-6 µm long; .5 µm wide.

Secondary Metabolites: Present; throughout the thallus medulla, usnic acid (other secondary metabolites: constipatic acid, protoconstipatic acid, +/- scabrosin 4-acetate 4´-butyrate (trace), +/- scabrosin 4-acetate 4´-hexanoate (trace) and +/- scabrosin 4,4´-dibutyrate (trace)).

Spot Tests: Cortex: C – medulla: K –, C –, KC –, PD –.

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