One of my regulars emailed these across growing on an Acer. Any ideas would be greatly appreciated cheers!

I would say with some certainty that this is Auricularia mesenterica, the tripe fungus.

 

basicaly feeding on the dysfunctional sapwood, indicating that at the very least the stem with the brackets is dying.

 

looking at the junction to the main stem its a co dom leader, mayber the tree has shut this down, or it just isnt getting sufficient support, it does have a very narrow point of attachment.

 

could almost certainly be carefuly removed if the tree is of value.
