Rinodina bolanderi H. Magn.

Data Set Maintenance: Data set compiled (from Sheard Sonoran Desert Flora Vol. 2 manuscript). Data set author(s): Bungartz F. (02-08-30). Data set not to be published after submission.

Nomenclature: Current taxonomic status: accepted or basionymous. Taxonomic rank: species. Currently accepted name Rinodina bolanderi H. Mahn. Rinodina. Physciaceae Zahlbr. (1898); Lecanorineae; Lecanorales.

Type Information: Basionym: Rinodina bolanderi H. Mahn. Type: Rinodina bolanderi H. Mahn.

Taxonomic Literature: H. MAgn.: Bot. Notiser 51 (1949).

Biogeography: Northern hemispheric; coastal, colline, submontane, and montane. Continent: Northern America (endemic). Checklist records: Mexico, Sonoran Desert, and United States and Canada (continental).

Ecology: Biotroph; lichenized; terricolous, bryophytic, lignicolous, corticolous, or saxicolous (shale, sandstone and igneous rock); episubstratic; growing sun-exposed or partially shaded; under conditions which are dry or moist.

Thallus: Crustose, subdivided into main (areoles) parts, areolate (primarily areolate); lobes plane, subconvex, or convex; separate thallus parts.5-.8-(1) mm wide; thin or thick. Thallus Outline: Sometimes fimbriate; usually indistinct or distinct (sometimes with hypothallus); persistent. Upper Surface: Light grey or grey-brown (dark), matt; not isidate; not sorediate. Lower Surface: Firmly attached attached; attached by the whole lower surface.

Upper Cortex: Present.

Reproduction Strategy: With sexual (and possible asexual) stages. Ascocarps: Apothecioid, orbicular, becoming adnate (broadly attached) or soon sessile (becoming), abundant, 1-1.6 mm in diam.. Margin: Smooth, persistent or excluded (with thin proper margin), distinct, 80-225 µm wide; without a thin rim between disk and thalline margin or with a thin, inner rim visible between disk and thalline margin (with thin, limiting proper margin). Disk: Plane or weakly convex (rarely becoming); black; pruinose, pruina white. Exciple: White. Parathecium (proper excipulum): Broad (expanding to 15-35 µm above), 10-25 µm wide, white, inspersed with crystals, dissolving in 10% KOH (atranorin). Amphithecium (thalline excipulum): Present; 70-200 µm wide, inspersed with crystals, crystals small (atranorin), abundant (atranorin), dissolving in 10% KOH (atranorin); photobiont sparse or abundant. Lower Amphithecium: Pseudoparenchymatous. Amphithecial Cortex: Present; 15-75 µm wide; outer cortical layer white; inner cortical layer white. Epithecium: Apical cells spathulate, dark brown or brownish red. Hymenium: 80-115-(145) µm high; white; not inspers. Interascal Hyphae: Distinctly branched, not or scarcely anastomosed. Hypothecium: 40-135 µm high; white; not inspers.

Asci: Clavate; 70-85 µm long, 17-27 µm wide; dehiscence lecanoralean.

Ascospores: Mischoblastia, Pachysporaria-type (Teichophila type: Physcia to Mischoblastia during development becoming Pachysporaria-type), or Physcia-type, c. 8 per ascus, spores 8 per ascus, ellipsoid; septa present; forming early during spore ontogeny (Physciaceae-type A); wall ornamented (more so in old spores).

Conidiomata: Present (immersed in thallus, ostioles dark).

Conidia: Bacilliform; 4-5 µm long; 1 µm wide.

Secondary Metabolites: Present; only in the upper part of the cortex (atranorin) or throughout the thallus medulla (zeorin), atranorin or hopane-6a,22-diol.

Spot Tests: Present reactions. Upper surface: K + deep yellow, C –, KC –, PD + yellow; cortex: KC + deep yellow, –, PD + yellow; medulla: K – C –, KC –, PD – lower surface: K – soredia: K – KC –.

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