California Gardening: Schefflera Black Spot, 1 by Jungleman

Can anyone tell me what is going on here? Only one of my Scheffleras has this odd spotting on the new growth. It began before the freeze. It is planted level with the grass / mulch, so it is not sitting too low. The spotting is not powdery and doesn't rub off. As you can see, one of the leaves is almost completely black. I have not seen any bugs on the new growth either, but then it could be a night time visitor. I really don't want to lose this plant. Please help!
