The crustose
thallus of
Lecanora panticapaensis ranges in colour from grey to greyish-yellow top yellow-green, and reaches a diameter of up to wide. The form of the thallus around its periphery is
areolate to lobulate. The areoles are convex, typically 0.6–1.2 in diameter and 0.5–1.5 mm thick. The
prothallus is usually indistinct, but if present, it is white and cottony, forming a zone around the thallus about wide. Bright yellowish-green
soralia are scattered on the thallus surface; the individual
soredia are typically 50–60
μm wide, but they can also aggregate to form larger consoredia that are 80–150 μm.
Apothecia occur frequently, and are 0.8–1.2 in diameter; they are
lecanorine in form with a flat, brown disc encircled by a margin of the same colour. The
asci contain eight
ascospores, which themselvea are
hyaline,
ellipsoid in shape, and measure 10.5–13.5 by 5.2–6.8 μm. Several
lichen products occur in
Lecanora panticapaensis:
atranorin,
epanorin,
zeorin, and
roccellic acid are major constituents;
muronic acid and
isomuronic acid are minor components, and there are trace amounts of
rhizocarpic acid. ==Habitat and distribution==
