if you pureed some roots and added it to the tea, could you possibly grow endomycorrhizal spores or would the chemistry be off? Is there another way that endomycorrhizae could be propagated in a tea? Would a tea like this be of any use if you did grow endomycorrhizae?
Endomycorrhizal spores, to the best of my knowledge sprout proximal to living growing roots or seed sprouts.
