I run
http://forestfungi.com.au/ and teach courses here
http://milkwood.net/category/mushroom-cultivation/
I'm in the process of re-stocking my cultures after a move interstate, but will soon have spawn, dowels, petri cultures etc.
I've had students fly in from Papua New Guinea, New Zealand and all parts of Oz, which has been wonderful, but I'm now working on an online course, covering everything from cloning a mushroom right through to harvesting and cooking. Students will get multiple cultures on petri dishes, as well as multiple tubs of grain spawn, dowels, and a bunch of resources to enable them grow lots of mushrooms.
