Orange fuzzy spots growing on my TEXAS front yard trees..what is it?

Question:We bought this house a decade ago and the trees have grown fine..
recently I put mulch in my gardenia garden and it grew orange round piles of fuzz.I took all the mulch out.Now I'm seeing little round orange fuzzy spots on my trees trucks..can someone in TEXAS tell me what this stuff is??

Answers:
Does it disappear after a few hours and then reappears someplace else the next day? If yes, could be slime flux...a botanical curiosity, no damage.
