Canomaculina subtinctoria (Zahlbr.) Elix

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 Canomaculina subtinctoria (Zahlbr.) Elix. Canomaculina. Synonyms: Parmotrema subtinctorium (Zahlbr.) Hale,
Parmotrema haitense (Hale) Hale,
Rimeliella subtinctoria (Zahlbr.) Kurok.;
Parmeliaceae Zenker (1827); Lecanorineae; Lecanorales.

Type Information: Basionym: Parmelia subtinctoria Zahlbr. Type: Canomaculina subtinctoria (Zahlbr.) Elix.

Taxonomic Literature: Elix, Mycotaxon 65: 477 (1997).

Biogeography: Subtropical, pantropical, and temperate; submontane, montane, and upper montane. Continent: Australasia, Europe, Northern America, and Asia-Tropical. Checklist records: Mexico, Sonoran Desert, and United States and Canada (continental).

Ecology: Biotroph; lichenized; corticolous or saxicolous; 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, irregular, lobed; lobes elongate or sub linear (to subirregular), horizontal (continuous) or imbricate; separate thallus parts 7-13 mm wide. Thallus Size and Differentiation: 4-15 cm in diameter. Thallus Outline: Orbicular. Upper Surface: Grey (turnig buff in the herbarium), glossy (shiny), smooth; fissurate; fissures reticulate; maculate; epruinose; not pseudocyphellate; ciliate; cilia slender, interspersed accross the thallus or rarely among isidia; isidiate; isidia laminal, cylindrical, ramified, sparse or coralloid (sometimes with cilia); not pustulate. Lower Surface: Present, brown (pale to dark), pale brown in the centre, dark brown along the margin; attached by holdfasts (true rhizines); rhizinate; rhizines abundant, black, not branched.

Upper Cortex: Present; prosoplectenchymatous (pallisade); epicortex present; porous. Photobiont Layer: Photobiont cells continuous. Medulla: White, loose; iodine reaction in Lugol's solution negative or in Lugol's solution positive (with Cetraria-type lichenan).

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, 3-8 mm in diam.. Margin: Smooth, persistent, distinct; isidiate; not ciliate. Disk: Excavate, brown. Exciple: White (grey). Epithecium: Apical cells brown. Hypothecium: White.

Asci: Clavate; dehiscence lecanoralean.

Ascospores: c. 8 per ascus, spores 8 per ascus, ellipsoid, 8-11 µm long, 5-8 µm wide, obtuse; septa absent.

Conidiomata: Present; immersed; formed all accross the thallus surface.

Conidia: Fusiform or cylindrical; 4-7 µm long; 1 µm wide.

Secondary Metabolites: Present; only in the upper part of the cortex (atranorin, chloroatranorin & usnic) or throughout the thallus medulla (all other substances), atranorin, chloroatranorin, consalazinic acid, protolichesterinic acid (and norlobaridone), salazinic acid, or usnic acid.

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