Bolder Lichen – Porpidia tuberculosa. A crustose Lichen with black “dots”. These are the fruiting bodies called soralia. Because of these, it is sometimes called called “Cigarette Ash Lichen”.
Crawfish Lichen – Ochrolechia parella. Another crustose Lichen. Look closely. The “pastry-cup” shapes are the fruiting bodies called apothecia. Because of these, it is sometimes called Crab’s Eye Lichen”.
