Data Set Maintenance: Data set compiled and standard item. Data set author(s): Kainz C. (02-09-05). Data set not revised; to be published after submission.

Nomenclature: Current taxonomic status: accepted or basionymous. Taxonomic rank: species. Bacidina. Lecanoraceae Körb. (1855); Lecanorales.

Taxonomic Literature: Ekman S., Opera Botanica 127: 1-148 [122-123] (1996).

Biogeography: Continent: Northern America (along the coast from southern California to southern British Columbia, endemic ?).

Ecology: Biotroph; lichenized; corticolous.

Thallus: Crustose, not subdivided (usually; never dissolving into granular goniocysts) parts, more or less rimose or areolate (primarily areolate); separate thallus parts thin. Thallus Outline: Irregular. Upper Surface: Pale grey (or pale green-grey) or grey-yellow; wrinkled (or warted).

Reproduction Strategy: With sexual (and possible asexual) stages. Ascocarps: Apothecioid, forming independently from the host thallus or mycelium, .4-.5-.6 mm in diam.. Margin: Lecideine/biatorine (margo thallinus rather thin, concolorous with the thallus, in at least some of the young apothecia covering 50-100 % of the proper exciple, soon excluded, but easily visible in section even in old apothecia), excluded, distinct. Disk: Plane or weakly convex (later), pale red, brownish yellow (or pale yellow, pale pink, pale orange, often mottled with different hues), or brownish red, epruinose. Exciple: Not carbonized (margo thallinus rather thin, concolorous with the thallus, in at least some of the young apothecia covering 50-100 % of the proper exciple, soon excluded, but easily visible in section even in old apothecia). Parathecium (proper excipulum): White or lemon (citrine), not inspersed with crystals. Epithecium: Apical cells not swollen (sometimes), slightly swollen, or distinctly swollen. Hymenium: 57-62-65 µm high; pale brown or white (or diffusely pale yellow to red-brown, usually darker in upper part than in lower part). Hypothecium: Very pale yellow or white.

Ascospores: Oval ("acicular, straight or slightly curved/sigmoid"), (25)-31-41-49-(57) µm long, (1.2)-1.6-1.9-2.2-(2.5) µm wide; septa present ((3-)3.2-3.9-5.4(-7) septa).

Conidiomata: Present (colourless, c. 100 µm diam.); immersed (in thallus).

Conidia: Filiform (non-septate) or curved; 9-16 µm long, .5 µm wide.

Secondary Metabolites: Present (apothecial amd pycnidial pigments: yellowish parts K+ intensifying, N-; brownish parts K+ purplish, N+ orange-red; sometimes Rubella Orange in proper exciple, hypothecium, and hymenium, sometimes Laurocerasi Brown in proper exciple and hymenium).
