I am having problems just trying to make predictions about the metabolites
of fungi in a single forests much less across continents. 

I agree with previous posting that authors must be cautious else they are
being reckless. The best thing to do is to ask around especially of locales
who have feasted upon the mushrooms you desire.  In addition people respond
differently to eating the same mushrooms so a single answer, cooking method,
sniff test, or color change will never id "safe" fungi for consumption or
recreation. Mother nature has too much fun keeping us on our toes. Therefore
" Let the buyer beware".

Actually, late last august, I collected Lactarius subvellereus in
mixed woods on our property.
It was prepared using the tradional Russian method, boiling and
changing the water twice and then packing in rock salt with a weight
on top.  The mushrooms were sampled a month later, and were quite
tasty.  However, (if you want the grimy details) my stools were a
little loose shortly afterwards, about 45 minutes.  Not exactly the
Runs, but just a little loose.  My friend with whom I prepared the
mushrooms reported the same effect.  We both tried tasting again
several times, always with the same "loosening" effect.   Drinking a
glass of vodka before eating the mushroom had no noticable effect
(other than the expected).  Although I fed what was left of my Salted
mushrooms to my chickens, my friend kept a jar and uses them when he
needs to "go".

I do not pronounce toxicity, but rather leave it to you, Joe Skulan,
to dicern whether this particular Lactarius is Toxic or not.
