Very bright yellow-green lichen seen on many mountain rocks in the area. Almost metallic in appearance in some lights. Stands out vividly.
Caution: Do NOT use iSpot to identify fungi to eat!
Some fungi are very poisonous so a mistaken ID could have serious consequences.
No interactions present.
I'm tempted to ID this as Rhizocarpon geographicum (the 'map lichen'), but not sure I can rule out R. lecanorinum here, which I keep looking for but haven't knowingly seen.
