The mushroom question is easy Steven. Since there is NO food value to a 
mushroom, simply avoid them all. The only reason we use them in our food 
is the flavoring.  There are no calories, no or only trace amounts of 
vitamins or minerals. Skipping them is the sensible thing to do

In that case, I hate to say it, but your education is sorely lacking in 
the fundamentals. Smelting for instance was discussed at length in the 
high school physics books I was reading by the time I was in the 3rd 
grade. Don't they teach anything in school anymore? Tanning leather for 
instance involves a long soaking in strong tea, and doesn't name the 
brand or genus of the tea, the important part was the tannic acid 
content.>
