Parmelia martinicana
Parmelia martinicana Nylander, 1885, p. 609.
TYPE COLLECTION.—Martinique, Tardin (H, holotype).
DESCRIPTION.—Thallus adnate, 3–9 cm broad, pale tan mineral gray; lobes irregular, subrotund, short, 2–5 mm wide; upper surface becoming rugose toward the center, densely isidiate, isidia initially papillate, cylindrical to irregularly thickened, simple or branched, rarely turning granular at the tips; lower surface black and sparsely rhizinate at the center, rugose, brown, and naked in a narrow zone at the margin. Apothecia not seen.
CHEMISTRY.—Cortex K+ yellowish (atranorin); medulla K–, C+, KC+ rose, P+ orange red (gyrophoric and protocetraric acids). The presence of gyrophoric acid was first demonstrated by Dr. S. Kurokawa on material in US. I confirmed his crystal tests with TLG. This unsuspected combination of acids has recently been found in the P. caperata group (W. L. Culberson, in litt.).
WORLD DISTRIBUTION AND HABITATS.—West Indies (Bermuda to Trinidad); on hardwoods in dry scrub woodland (sea level to 1,000 m).
This is one of the few conspicuous foliose lichens in the dry scrub woodland. The isidia are sometimes quite deformed with a tendency to become granular. Closely related P. raunkiaeri Vainio, another West Indian endemic, does have definitely pustular sorediate isidia and protocetraric acid but appears to lack gyrophoric acid.
SPECIMENS EXAMINED.—Morne Couliabon, Elliott 1538 pro parte (TUR). Hale collections: 2 (35632), 3 (35654), 4 (35660, 35662), 5 (35544), and 8 (35761).
