Indigenous people through most of this lichen's range in North America traditionally make a yellow dye from this lichen by boiling it in water. Many of the traditional dyes of the Scottish Highlands were made from lichens including red dyes from the cudbear lichen , Lecanora tartarea , [ 1 ] the common orange lichen, Xanthoria parietina , and ...
Ramalina menziesii, the lace lichen or fishnet, is a pale yellowish-green to grayish-green fruticose lichen. It grows up to a meter long, hanging from bark and twigs in a distinctive net-like or lace-like pattern that is unlike any other lichen in North America. [3] It becomes a deeper green when wet. [3] Apothecia are lecanorine. [3]

Two obstacles are often encountered when eating lichens: lichen polysaccharides are generally indigestible to humans, and lichens usually contain mildly toxic secondary compounds that should be removed before eating. Very few lichens are poisonous, but those high in vulpinic acid or usnic acid are toxic. [146] Most poisonous lichens are yellow.
It was only added to the North American list in 1984; previous records actually referred to a different species. [9] Unlike some lichens, D. canescens occurs in abundance on both calcareous and siliceous substrates. [10] It occurs on rocks, old walls, and tree trunks, [11] favoring nutrient-enriched areas, such as birds' perching stones. [12]
