Dan, your knowledge of fungi is impressive and your enthusiasm for them is
admirable. Every maligned life form should have such a courageous champion.
Maybe someone will take up for the foresters. Till then, I would like to make
just a few observations on your comments about forestry.
Forestry is not "timber, timber, timber" as you say. But, timber is the
economic commodity that drives the forest industry. Yes, fungi are a major
componant of the overall biomass (I can go along with your figures. I don't
have any better ones off the top of my head). But can you make a decent
two-by-four out of mushrooms? Foresters are generally cognizant of the
importance of mycorrhizae to trees. Most foresters are aware, if not well
informed (admittedly I am not), of the commercial value of fungi to those
landowners wanting to undertake the labor intensive effort to cultivate or
harvest them. If you are suggesting that mushrooms should take the economic
place of trees as a forest commodity, I just don't see those kinds of market
forces at work here. Forestry is more about maintaining long term productivity
in the face of market demands for a resource depleting commodity. I would say
that you can't see forestry for the mushrooms.

Gifford Pinchot's comments a hundred years ago are not the sum of all forestry
knowledge. However, mycorrhizae are generally addressed by forestry as a soil
componant. In a way, Pinchot was on the mark. Mycorrhizae are not "required"
to grow trees in the strictest sense.
If you want to grow truffles, more power to ya. But, unless they can really
take the place of trees in terms of forestry productivity, maybe you do need a
field for mycostry. Maybe you need an "alt.mycostry" as well.
