There are currently many types of edible mushroom home grow kits you can purchase on line. Search for "home mushroom kits". You will get hundreds of hits.

What type of fungus could I keep as a houseplant (I realise fungi are not plants)? I need to know because my room receives no sunlight and has basically the same environment as a cave. I am leaning towards N. Gardeneri, but any other suggestions welcome.
