Data Set Maintenance: Data set compiled (Flora of Australia Vol. 55 Lichens-Lecanorales, Parmeliaceae). Data set author(s): Nöske, N. M. @EXCL@ Bungartz F. (06-06-04). Data set not revised; to be published after submission.

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

Type Information: Basionym: Parmelia sulcifera Kurok. Type: Parmelia sulcifera Kurok.; type specimen label data: S. Kurokawa 6450; holo: TNS; iso: ANUC.

Biogeography: Southern hemispheric. Continent: Australasia. Checklist records: Australia (rare, endemic, in rain shadow areas of central and southern tablelands of N.S.W.).

Ecology: Lichenized; terricolous (found on soil and rarely spreading over pebbles).

Thallus: Foliose, irregular, lobed; lobes linear (sublinear), imbricate; separate thallus parts.7-2 mm wide. Thallus Size and Differentiation: Up to 6 cm in diameter. Upper Surface: Lime green (pale yellow-green; lobe margins often blackened towards apices), convex, matt, smooth (smooth to slightly rugulose), pulverulaceous (becoming pulvinate); immaculate; not isidate; not sorediate; lobulate (laciniae revolute to convolute, subdichotomously branched, often entangled and growing over primary lobes, +/- subascending at apices, 0.3-0.5 (-1) mm wide, without lobules). Lower Surface: Present (partly canaliculate), yellow (straw-yellow to light brown, usually dark brown or black towards apices); attached by holdfasts (loosely adnate to unattched but remaining intact); rhizinate (often grouped subapically 0.2-0.6 mm long); rhizines sparse or moderately abundant, yellow (concolorous with lower surface), not branched (tufted or not).

Reproduction Strategy: With sexual (and possible asexual) stages (but rare, subpedicellate). Ascocarps: Apothecioid, 1-3 mm in diam.. Margin: Smooth, distinct (involute and +/- undulating). Disk: Excavate, red or dark brown.

Secondary Metabolites: Present; usnic acid (other secondary metabolites: hypostictic acid, hyposalazinic acid and +/- hypoconstictic acid).

Spot Tests: Cortex: KC – medulla: K + yellow changing to red (then pale reddish), C –, PD –.
