Camera test: lichenized fungi

[urbpan]

Here again I'm testing the camera's macro ability--these are lichens and mosses growing on the surface of a storm drain. I'll have to assume here that the mosses started it, and then the lichen fungi found the moss covered metal to be close enough to earth to colonize. My field guide doesn't have a section on lichens growing on steel. These are probably Cladonia sp., but again I'd love input from the real experts.


This crustose lichen on smooth tree bark is probably something in Lecidela, Lecidea, or Porpidea.
