Pleurotus - (Pleurotus ostreatus) - may be called oyster,abalone, or tree mushrooms, and are some of the most commonly cultivated edible mushrooms in the world.
Pleurotus means “side ear”, from Greek - πλευρή (pleurē)
Reindeer Lichen - (Cladonia rangiferina) - Other common names include reindeer mossandcaribou moss, but these names may be misleading since it is not a moss. Found primarily in areas of alpine tundra, it is extremely cold-hardy. The Inland Dena'ina used reindeer lichen for food by crushing the dry lichen and then boiling it or soaking it in hot water until it becomes soft.
