I love plants and fungi.
So how could I not like a lichen? It is both plant(algae) and fungi.
This is called symbiosis.
I hate to admit that I picked this up, stuck it in the pocket of my coat and forgot about it.
Later, I reached in and found this dried up wad.
Amazingly, it plumped back up when I put a few drops of water on it.
I chopped it into pieces to put under the microscope.
Do not worry about its survival. All the pieces are happily growing in one of the terrariums.
