Japanese Maple

Does anyone know what disease this is on my Japanese Maple? Here are two closeup
photo's and one far away.

No worries it is Lichen.

You can look on line to see how to kill it but I have it in all verities on my trees and it doesn't seem to hurt them.
It is also an indicator of clean air.
Really slow growing trees have more of it because the bark doesn't shed it off fast.

It doesn't seem to bother the tree, and it is producing seeds right now. I just
wanted to make sure it wasn't anything that would kill it.

Thank you

I tried to grow the Bloodgood Japanese Maple here but I couldn't keep enough water on it.
It was in the shade and doing great as long as it stayed wet.

I bought a small Bloodgood years ago, when I lived in a house with shade in the back. It was
growing really well, but then I moved.

I believe that Worth is right!

At our Master Gardener's course, we were told that Lichens are harmless yet people believe they are harming the tree when they are merely being opportunistic. I just let them be.

They can also use Lichens to age rocks in many ways to see how long something has been around.'
It is called lichenometry I first read about it years ago.https://www.google.com/url?sa=t&rct=...rg0DACz1zmZuIA

It always wears on me when people think carbon dating is the only method used to tell the age of something.
There are many ways.

When flint is chipped it starts growing a layer on it.
They can tell by the thickness of the layer approximately how long ago the flint was chipped to make the spear point.

I hope I get this straight.
It is pictures of various lichen growing on rock and dead limbs in trees and on the ground.
Also you will see fungus growing on old mesquite with lichen growing on it.
Last you will see a bromeliade growing high up in a tree and a close-up of one on the ground.
My place is covered in these various critters of all types.
The pineapple is a bromeliade.
To think the last two pictures depict a bromeliade and the thing is kin to a pineapple.
The many dead limbs are from the long horn stem girdleing beetle.
They lay their eggs and then girdle the stem so it dies and falls to the ground.
I let to old half dead mesquite stay around so the wood peckers have something to eat on.
They love the things.
My neighbor thinks I am crazy for this.
He asked me one time when I was going to cut them down and I told him I wasn't because the wood peckers like them.
My attitude is to try to live with nature not control it.
His yard is devoid of all life.
