Xanthoparmelia eilifii 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. (04-11-01). Data set not revised; to be published after submission.

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

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

Taxonomic Literature: Taxonomic notes: based on Parmelia dahlii Kurok., nom illeg. Bull. Brit. Mus. (Nat. Hist.), Bot. 15: 235 (1986).

Biogeography: Southern hemispheric. Continent: Australasia. Checklist records: Australia.

Ecology: Biotroph; lichenized; terricolous (scattered on soil and debris in mallee scrub); growing under conditions which are dry (subarid shrubland in inland Australia).

Thallus: Foliose, subdivided into main (weakly convolute, distorted, often entangled) parts, isotomic-dichotomous (subdichotomously branched), lobed; lobes elongate; separate thallus parts 1-2-(3) mm wide. Thallus Size and Differentiation: Up to 10 cm in diameter. Upper Surface: Lime green (pale yellow-green), matt, rough (slightly rugulose); immaculate; with patches (loosely disjointed patches); not isidate; not sorediate; lobulate (laciniae 0,3-0,5 mm wide, often growing over primary lobes or occasionally developing as revolute lobules in thallus centre and along margins of older lobes). Lower Surface: Present (partly canaliculate), brown (pale brown to brown); attached by holdfasts; rhizinate; rhizines sparse or moderately abundant, brown (concolorous with lower surface), not branched.

Medulla: White.

Reproduction Strategy: Only known as sterile, asexually reproducing form.

Conidiomata: Absent resp. not observed.

Secondary Metabolites: Present; throughout the thallus medulla, norlobaridone (norlobaridone (major); other secondary metabolites: loxodin (minor)) and usnic acid.

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

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