Please tell me how to get rid of a weird, green, powdery mold ??????

[gordon stelter]

I have a piano that was externally covered with a 
bizarre-smelling, bright green powdery organism. I
wiped as much as I could off with alcohol, but it
still smells weird and sort of dangerous. ( How
dangerous is it ??? )
     How can I get rid of this ? All I have been able
to think of is putting a plastic tent over the piano,
and pouring a gallon of lacquer thinner 
- or something- into a pot under the tent, in hopes
that the fumes will kill the spores ? I might take
some of them to the University, too, to try to
identify them.
    The strange thing about this is that the piano was
not in a very humid environment, but the powdery mold
grew 1/16 inch deep in places on the case.
