Xanthoparmelia barbellata (Kurok.) Hale

Data Set Maintenance: Data set compiled (Flora of Australia Vol. 55 Lichens-Lecanorales 2, Parmeliaceae). Data set author(s): Nöske, N. M. (04-09-22). Data set not revised; to be published after submission.

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

Type Information: Basionym: Parmelia barbellata Kurok. Type: Xanthoparmelia barbellata (Kurok.) Hale.

Taxonomic Literature: Mycotaxon 20: 79 (1984).

Biogeography: Southern hemispheric; subalpine. Continent: Australasia. Checklist records: Australia and New Zealand.

Ecology: Biotroph; lichenized; terricolous (or pebbles) or saxicolous; growing sun-exposed, under conditions which are dry.

Thallus: Foliose, subdivided into main parts, irregular (becoming laciniate), lobed; lobes imbricate (or not); branches irregular; applanate (moderately flattened); separate thallus parts 1-3 mm wide. Thallus Size and Differentiation: 4-6 cm in diameter. Upper Surface: Lime green (darkening), matt or slightly glossy (shiny), smooth; immaculate; not isidate; not sorediate; not lobulate. Lower Surface: Present, brown (pale brown to brown, occasionally orange) or dark brown; rhizinate; rhizines sparse or moderately abundant (grouped subapically), pale brown or dark brown (occasionally orange), not branched or branched, dichotomously branched.

Medulla: White (intermittently yellow or orange adjacent to lower cortex).

Reproduction Strategy: With sexual (and possible asexual) stages. Ascocarps: Apothecioid, soon sessile, 2-8 mm in diam.. Margin: Distinct (thin, involute, becoming entire and deeply lacerate). Disk: Excavate (then undulate-distorted), brown (brown to dark brown and shiny).

Ascospores: 6-7 µm long, 3.5-5.5 µm wide.

Conidiomata: Absent resp. not observed.

Secondary Metabolites: Present; throughout the thallus medulla, consalazinic acid, constictic acid, norstictic acid, salazinic acid, skyrin (in pigmented medulla), or usnic acid.

Spot Tests: Cortex: KC – medulla: K + yellow changing to red (white medulla K+ yellow then dark red; pigmented medulla K+ violet), C –, PD intense + orange.

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