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

Taxonomic Literature: Ekman S., Opera Botanica 127: 1-148 [117-118] (1996).

Biogeography: Continent: Northern America (known from a few localities in Marin, San Mateo, Monterey, and Santa Barbara Counties in the south and central parts of California; endemic ?).

Ecology: Biotroph; lichenized; corticolous.

Thallus: Crustose, not subdivided parts, granular, rimose, or areolate (primarily areolate); separate thallus parts thin or thick. Thallus Outline: Irregular. Upper Surface: Grey or grey-yellow; special structures present: (goniocysts (21-)30(-52) µm in diam.); not wrinkled or wrinkled (or warted).

Reproduction Strategy: With sexual (and possible asexual) stages. Ascocarps: Apothecioid, forming independently from the host thallus or mycelium, .4-.5-.7 mm in diam.. Margin: Lecideine/biatorine, excluded (finally), distinct. Disk: More or less plane to weakly convex (later), pale brownish yellow (or pale pink to pale yellow) or brownish red, epruinose. Exciple: Not carbonized. Parathecium (proper excipulum): White, brownish red, or lemon (citrine), not inspersed with crystals. Epithecium: Apical cells not swollen, slightly swollen, or distinctly swollen. Hymenium: 57-64-73 µm high; brown (pale yellowish or reddish) or white. Hypothecium: Very pale yellow, white, or brownish yellow.

Ascospores: Oval ("acicular, straight to curved to sigmoid"), (31)-35-41-46-(53) µm long, (1.9)-1.9-2.4-2.8-(3.3) µm wide; septa present ((0-)3.6-5.7-7.5(-9) septa).

Conidiomata: Present (of two types: 70-100 µm in diam., conidia filiform, curved, non-septate, 7-12 x 0.6-0.8 µm or 75-225 µm in diam., conidia bacilliform, straight, non-septate or some 1-2-septate, 7-9 x 1.6 µm); more or less immersed (in thallus).

Conidia: Filiform (or bacilliform) to curved; 7-12 µm long, 1 µm wide.

Secondary Metabolites: Present (pigmented parts of apothecia K+ green-brown, N-; sometimes Arnoldiana Brown in proper exciple, hypothecium, and hymenium).
