For my Students - - -
Just so you know my science teacher brain was NOT asleep on the this trip - - -
I observed this beautiful lichen covered rock and captured it with my camera JUST so I could share it with you!!!!
(That would be pronounced lie-kin, Jessica!!)

I´ll have to show this to my students next week when we study vegetation in World Geography! Thanks, Teacher!
Do you know all about lichens???? If not - - - you ask me, I'll be GLAD to share!!
I MAY take you up on that! I´m out of my league teaching World Geography --- WAY out of my league! Just because I've traveled a lot doesn't make me an expert in all things related to the subject!
Well, here's the "short course" Lichens are not plants, as we had originally thought - - - but rather are a fungus with either an alga or a cyanobacteria living in symbiosis with them. The fungus provides the support and the alga or bacteria can perform photosynthesis and provide the food - - - thus both are happy as clams at high tide.
