The fungi themselves, growing alone, are not called "mycorrhizae".
VAM mycorrhizae are produced by any of about 200 fungi belonging to
the genus Glomeromycota when they grown on or in or in sufficiently
close proximity to tree roots. A phylogenetic tree for that genus
can
be found at http://www.lrz-muenchen.de/~schuessler/amphylo/. Note
that none of the species is called "mycorrhizae".

If there's no fungus then there are no mycorrhizae. If there is no
tree there are no mycorrhize. It's when you have _both_ that
mycorrizae occur.



So then grass, marigolds, grapevines, not being trees, don't have
mycorrhiza?

Google "figurative language".
