How to get Slime Mould in Israel

Hi, I'm interested in Slime Mould for artistic purposes. I understand that I can't get it by ordering online since it is a biological material and should have a special permission - ?

The local representatives are looking for a proof that slime mould is safe to use at home. Would you happen to know of such resources, or of a way to get the slime mould.

I understand it might be available here in nature, if so, where would you look for it?
