Often slime molds are hard to tell apart in this, their slime stage. Unlike
a fungus, a slime mold is really no indication of the tree's health
one way or the other. They're susceptible to drying out, which is why it's
fond of your moisture-retaining branch scar, conveniently up where air
currents can better carry away its spores. If you can't dry it out then I
suggest the standard artillery - hose & scrub brush. There's really no
"cure" for them, and I couldn't say how that treatment would affect its
spreading. Some people just leave them alone.

rec.gardens with the details of my problem, but woulld appreciate any help
in identifying the slime and its cure.
