Data Set Maintenance: Data set compiled (Flora of Australia Vol. 55 Lichens-Lecanorales, Parmeliaceae). Data set author(s): Nöske, N. M. @EXCL@ Bungartz F. (06-05-20). Data set not revised; to be published after submission.

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

Type Information: Basionym: Xanthoparmelia nigrocephala Kurok. Type: Xanthoparmelia nigrocephala Kurok.; type specimen label data: S. Kurokawa 6480; holo: TNS.

Taxonomic Literature: Ann. Tsukuba Bot. Gard. 8: 24 (1989).

Biogeography: Southern hemispheric; alpine. Continent: Australasia. Checklist records: Australia (apparently rare species from Kosciusko Natl Park (N.S.W.)).

Ecology: Lichenized; saxicolous.

Thallus: Foliose, irregular, lobed; lobes elongate, imbricate; rounded (margins slightly thickened) at the front; plane; separate thallus parts 1-2.5-(5) mm wide. Thallus Size and Differentiation: 5-10 cm in diameter; apex rounded (or shallowly notched). Upper Surface: Lime green (blackening on older lobes), glossy (shiny), smooth (at margins); immaculate; wrinkled (becoming rugose in thallus centre); isidiate (dense, short); isidia central, globular (subglobose, constricted near base, slender, slightly inflatened), ramified, coralloid, darkened at the tip (black-tipped on terminal branchlets, syncorticate and intact); not sorediate. Lower Surface: Present, brown (pale tan to brown, shiny, rarely dark brown in places); attached by holdfasts (adnate to tightly adnate); rhizinate (short); rhizines sparse or moderately abundant, brown (concolorous with lower surface), not branched.

Ascospores: 6-8 µm long, 4.5-5 µm wide.

Conidiomata: Present (but rare).

Conidia: Bifusiform; 6-7 µm long; .5 µm wide.

Secondary Metabolites: Present; consalazinic acid, salazinic acid, and usnic acid.

Spot Tests: Cortex: KC – medulla: K + yellow changing to red, C –, KC –, PD + orange.
