Blackish green jelly stuff on pear tree and ground?

There is a black green jelly substance on our pear tree not at the base but on the first limbs, I thought it was a fruit tree fungus but today we found it on the ground probably a hundred feet or more away where I have several lilies and other flowers planted. Does anyone have an idea? Oh and my pear tree is basically dead now, I have never seen anything like this, It literally looks like blobs of black/green/purple mucous gel stuff.
