So the only thing I can find in the forum archives and elsewhere is that people have experimented with mahogany sawdust.with varying levels of success. I have found nothing in fungal literature suggesting it
should not be used for edible mushrooms. I have been offered suggestions of potential mixes largely to get the particle size up and increase interstitial oxygen. I would like to use the mixes in garden beds for Stropharia, and also mix with
coffee grounds for oyster mushrooms, though when I say this most folks say beds are unsuitable for oyster mushrooms.
Any thoughts?
