Image #215 – How are you lichen it?

SAMSUNG CSCLichen and mushrooms like to hang out together but they are different. Since I am without my reference books I can’t say definitively what all of those lovely colored beings are.  Mushrooms are the fruiting body of fungus while lichens are composite beings that have fungi and a photosynthetic partner growing together in a symbiotic relation. (Thank you Wikipedia.)  The pale green and the red & white growth are definitely lichen. But the tan colored growth has me stumped.  There are mushrooms that are similar to this so …. ?  This bark is on an old oak tree in the oak grove that I featured a couple of posts back (Oak Cathedral). ❧
