Alan, I got Moonshine from that really cool nursery - mostly succulents - at the far north end of Tucson, maybe even Marana. Darned if I can remember the name... but they had lotsa great plants for pretty good prices. Grew fine for me in a shady spot outside.
Shannon, I don't have a clue, but it sure doesn't sound good. Just for grins and giggles, you might try spraying it with Chamomile Tea, or dusting it with cinnamon - both are anti-fungals.
Of course, you might just want to wait until someone comes along who actually knows what they're talking about.....
