No, there are *many* fungal taxa that could be considered mycorrhizal.

This might be the case for those whom have never read anything
about plant biology. As this newsgroup is the "plant" stem ;)
of the bionet hierarchy, one would expect this not to be the case.

Not really. Not in terms of taxonomy or systematics, albeit there 
are some related species that may be classified as belonging to the
same family.  Mycorrhizae refers to several kinds of fungal structure,
not taxonomic status. Some fungi 'behave' this way - that is,
producing particular structures, others 'behave' in other ways.
Two main forms of mycorrhizae are: Ectomycorrhizae, which, as the
prefix 'ecto-' suggests, form on the outer part of plant roots,
and Vesicular-Arbuscular Mycorrhizae (often called 'VAM'), which form
by fungal hyphae (structurally analogous to fine root hairs or veins)
infiltrate the plant root structure.

Mycorrhizal research is not new, nor are the potential applications of
this research in the fields you mention. I would have little faith in
any 'professional' who lacked even fundamental knowledge on this.

How can this be so, if what you wrote next is also true?

Just another perspective.
