General Appearance: Long, hanging, greenish-gray thallus pierced
by many large, angular holes so that it resembles a net. Individual
thalli are often 25-40 cm (10-16 in) long.
Thallus: Fruticose, composed of hanging, flattened, netlike branches; attached at a single point. Individual strands highly variable in width, 0. 5-5.0 mm (.02-.20 in)wide, 0.5 -1.5mm thick. Exterior smooth or longitudinally wrinkled, dull; yellowish- gray or greenish-gray when dry, becoming yellowish-green when wet. Apothecia: Rare Soredia: Lacking. Isidia: Lacking. Comments: This large, easily recognized lichen frequently drapes the trees along streams. It is the only common lichen with a net-like thallus. Ramalina menzeisii is frequently called “Spanish moss” because of its resemblance to the flowering plant called Spanish moss which drapes the tress of southeastern coastal regions in a similar fashion. |
