nothing to do about it.. usually not terminal ... its up to you whether it will drive you insane. ...

besides .. its that time of year...

Thanks ken for the link, yes it does look like gunmosis. I guess I will just leave it alone, if it doesnt harm the tree. Also the articles I read related to the link suggested that this happens in cherry and peach fruit trees. I dont think my tree ever produces cherry, it does have pink flowers in the spring. I am assuming the trees I have are just landscaping cherry trees and not the fruit trees.
Hoping someone could ID the tree for me.

whether fruiting or not ... they are prunus ...
and if i am not mistaken.. many of the most common fruits are prunus ....

if you want a proper ID .... you would need a pic of a flower.. the whole tree ... and a leaf .. and maybe you will get close ... and if you get no answer here.. you would post at the name that plant forum for a 2nd shot ..

Here is a link that might be useful: i dont know the place.. just sums up prunus pretty well

you have, from the pics, an 'ornamental' (fruitless) cherry tree named 'wine' or 'burgundy' something after the leaves.

all cherry, plum, peach trees weep a certain amount of sap, much like pine trees. they leave from wounds in the bark that can be caused by pruning, abrasion, insect infestation, or natural 'growth' breaks in the bark

the clean, dried sap is a non unpleasant 'resin' type incense.

I would scrape some of that away, and see if you have insects chewing up the tree bark (you'll see holes going into the branch) - that's one of the prime causes around here.

Yes, you should check for borers. Otherwise sap on prunus can be mechanical (not this case) or gumosis.
