I just found a decent source of sawdust. However, it is 90%  mahogany, sapele, & red grandis. My goal would be to get edible mushrooms and mushroom compost to use in the garden.
Does anyone know anything about the use of these tree species in growing edible mushrooms?

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?
 
I think I'll just lie down here for a second. And ponder this tiny ad:
