In 1854, Italian lichenologist Abramo Bartolommeo Massalongo renamed it Menegazzia terebrata.
Menegazzia terebrata has a glossy blue-grey thallus and a black, wrinkled undersurface.
[1][3] A potassium hydroxide test will produce K+ yellow results on the surface and medulla of this lichen.
It prefers acidic species of tree, including Alder, Beech, and Northern white cedar.
[7] Menegazzia terebrata was found to be an indicator species of clean air in Western Oregon and Washington.
