Maple issues

[coolbrze]

Two things on this Maple tree, please educate me...

1. The rotten area from the dead limb & down that's watery, looks like a fungi on it also
2. The sm. black dry crud on localized parts of the tree

Looks like bacterial wetwood or slime flix

Agree & the "crud" looks like dark lichen.
