Powdered Sunshine Lichen
Powered sunshine lichen is named for its yellow powder-like surface.
Identification: The photo here is a highly dubious ID, and potentially misleading, since powdered sunshine lichen has yellow fringes, rather than these brown or black fringes. Only the shape is similar. This photo was taken in late winter. This is a foliose (leaflike) lichen, and while some lichens tend to lay flat against their substrates, this one is more wrinkled and loosely attached. The whole surface may be yellow, or just the edges. Fruiting bodies (apothecia) are uncommon.
