Mushrooms in desert-like surroundings?

Hi,
I have a question. I live on the very dry small Island of Aruba, and I have seen (poisonous) mushrooms here once, after prolonged rains, about 18 years ago. Since then nothing. Water is expensive here. Is there still a possibility for homegrown mushrooms without making a big 'reversed' greenhouse (do not know how else to call it, but something to keep things cool and dark, wich is hefty in price to make and maintain).

We grow edible mushrooms in a cardboard box full of compost under our sink. It's a commercially sold growing kit. Doesn't smell. Quite successful.

We live in a hot dry climate, and all of our local, common, outdoor mushrooms are poisonous. Do you have a gardening supply store nearby? They might have a kit for a cheap price? Whatever you do, I'd stick to indoor growing, preferably with bought mushroom spore

Thank you for that tip, I have not seen one, but will intensify my search for them!

Maria,If you can get them there-don't know the rules/regs both Field & forest and Fungi perfecti sell grow kits-they are 5 lbs bags that are self contained. You can do them under the sink-on a counter, all you have to do is create a "tent" of plastic over them-to keep humidity in. Then mist them a couple of times a day just watch them. *If your water is treated I would find a different source-we had a number of folks kits go south-I figured out they were using "city" water!
