I've got loads of the stuff. Can't stop it multiplying. You can also get some from a naturopath doctor at this link http://www.hehlis-holistics.com/index2.htm. That is where I got mine last year. You send a small donation which goes to Ormond Street Kids hospital and in return you get a small container which will breed and get bigger.
If no luck I will send you some. Have you had it before? It is not exactly a gourmet delight.
