[Mycology] Edibility of Russula and Lactarius

[Joe Skulan]

Perhaps this is not the ideal forum for these questions, but I have  
exhausted other options.

1. Are there any toxic species of Lactarius that it is known cannot  
be detoxified by the Russian method of soaking in several changes of  
water, boiling and salting?

2. Are any russulas known to be toxic other than R. emetica?

By toxic I mean toxic, as in eating them will make you sick. I do not  
mean that it might make some people sick, or that we don’t know if  
it’s toxic or not so we will assume it is. I don’t want general  
warnings about being careful, I certainly don’t want information on  
“edibility” that mixes toxicological information with subjective  
judgments on taste. I’m growing very frustrated with the poor quality  
of information on toxicity provided in guides, most of which seem to  
be written by people with very limited palates.

Cheers,

Joe Skulan
