Menegazzia terebrata

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.
