Exactly...and to carry your example forward things in the blue berry family
(Ericaceae) have mycorrhizae that are notoriously specific, obligate, and
difficult to culture. But if the OP is looking for a generalist, feel-good
addition to the plant or soil matrix, opt for the old standard - Pisolithus
tinctorius.
My view of this, however, is that plants generally are already colonized by
such fungi and the addition to existing plants may be unnecessary.

It matters because not all plants use mycorrhizae fungi to assimilate
nutrients
and water from soil. It's basically host specific and a variety of
different
fungal threads usually act in unison to help plants which normally have
trouble
with their poor root systems. Blueberries and roses are just one example
of two
plants, same family, which have poor root systems.

Sorry for being ignorant, but does that matter?
I mean, aren't there generically "good" micorrhizal fungi?
What is the procedure?
