Lecanora parasymmicta

Ciri dan struktur

Lecanora parasymmicta differs from L. symmicta, the most similar species, by its areolate-rimose thallus (vs. areolate to leprose thallus), blackish hypothallus (vs. hypothallus indistinct), larger apothecia (up to 1.7 mm diam. vs. up to 1 mm diam.), absence of thalline excipulum from the beginning (vs. presence of thalline excipulum when young at least), narrower paraphyses (1–1.5 μm vs. 2–2.5 μm), larger ascospores (11–18 × 4–7 μm vs. 9–15.5 × 4–5 μm), smaller pycnoconidia (12–21 × 0.5–0.8 μm vs. 18–25 × 0.5–1.0 μm), chemical reactions (thallus K± slightly yellow, C–, KC– and UV– vs. K–, C± orange, KC± slightly yellow, UV+ dull orange), and the presence of placodiolic acid (vs. presence of arthothelin and ±thiophanic acid). Thallus corticolous, crustose, areolate to rimose but not leprose, light olivish gray to light gray, margin determinate, not pruinose, 60–200 μm thick; cortex hyaline, 5–10 μm thick; medulla often intermixed with algae and even with bark layer, small crystals in cortex or between algae, dissolving in K; photobiont coccoid, cells globose to ellipsoid, 5–15 μm. Hypothallus blackish. Apothecia abundant, rounded, often contiguous or even coalescent, emerging on the surface of thallus and sessile when mature but margin generally attached to thallus surface, constricted at the base, 0.3–1.7 mm diam. Disc flat in the beginning and soon convex, smooth or becoming rugose by apothecia adjoining, not pruinose or slightly pruinose, pale yellow in the beginning and slightly darker when mature, sometimes with dark spots (algae), 180–400 μm thick; biatorine. Thalline excipulum absent from the beginning, proper excipulum present and sometimes slightly paler than disc, more distinctive when young, hyaline but yellowish brown to pale brown at periphery with granules which dissolving in K, periphery color same to epihymenium, ca. 90 μm wide laterally and 70–80 μm wide at periphery, disappearing to the base.
