I am looking for a source of a current source of mushroom spawn suppliers.
Alcona County Michigan mushrooms
I do not know the answer to your question. I do suggest that you contact the University of Michigan at Dearborn; they have a mushroom garden and I expect that they will be able to provide you with reliable sources for mushroom spawn. Their website is http://www.umd.umich.edu/eic/research/mushroom.html, the phone number is (313) 593–5338, and the email address is firstname.lastname@example.org.Thank you for contacting Ask an Expert.
