Data Set Maintenance: Data set compiled (from Sonoran Desert Lichen Flora Vol. 1). Data set author(s): Bungartz F. (02-10-10). Data set to be published after submission; February 2002.

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

Type Information: Basionym: Parmelia goebelii Zenker. Type: Bulbothrix goebelii (Zenker) Hale.

Taxonomic Literature: Hale, Smithsonian Contr. Bot. 32: 14 (1976).

Biogeography: Subtropical and pantropical; colline, submontane, and montane. Continent: Northern America, Southern America, and Asia-Tropical. Checklist records: Mexico and Sonoran Desert (in the state of Sonora).

Ecology: Biotroph; lichenized; corticolous; growing sun-exposed, under conditions which are dry.

Lichen Photobionts: Primary photobiont present; chlorococcal. Primary photobiont taxonomy: Trebouxia; Trebouxiaceae; Trebouxiales.

Thallus: Foliose, subdivided into main (lobes) parts, and secondary (apices sometimes dissected) parts, irregular, lobed; lobes elongate (sublinear), imbricate (moderately); separate thallus parts 2-8 mm wide. Thallus Size and Differentiation: 2-8 cm in diameter; apex rounded or truncate (subrotund, sometimes dissected). Thallus Outline: Irregular. Upper Surface: Pale grey, plane or subconvex, glossy (shiny), smooth; maculate; epruinose; not pseudocyphellate; wrinkled; ciliate; cilia slender (not slender but bulbate!!!); isidiate; isidia laminal, cylindrical, sparse or coralloid, darkened at the tip or sometimes concolorous throughout, not paler or darker at the tip; not pustulate; not sorediate. Lower Surface: Present, black, black in the centre, pale grey along the margin; attached by holdfasts (true rhizines); rhizinate; rhizines abundant, black, branched, irregularly branched.

Photobiont Layer: Photobiont cells continuous. Medulla: White; iodine reaction in Lugol's solution positive (cell walls with isolichenan).

Reproduction Strategy: With sexual (and possible asexual) stages. Ascocarps: Apothecioid, forming all across the thallus surface, all across the surface, independently from the host thallus or mycelium, soon sessile, sparse, 1-2 mm in diam.. Margin: Smooth (inner ring, ecoronate), persistent, distinct; isidiate (outer ring). Disk: Excavate, dark brown or brownish red, epruinose.

Asci: Clavate; dehiscence lecanoralean.

Ascospores: c. 8 per ascus, spores 8 per ascus, ellipsoid, 8-10 µm long, 4-6 µm wide; septa absent.

Conidiomata: Absent resp. not observed (not seen).

Secondary Metabolites: Present; only in the upper part of the cortex (atranorin & chloroatranorin) or throughout the thallus medulla (gyrophoric acid), atranorin, chloroatranorin, or gyrophoric acid.

Spot Tests: Cortex: KC + deep yellow, C –, KC –, PD + yellow; medulla: K –, C + red, KC + red, PD –.
