I am not been harsh the book has mistakes on nearly every page.
first page tylopilus fellus doesnt contain muscarine, and isnt poisonous, it is just bitter tasting slime.
second page boletus luridus nearly every other book discribes as edible when cooked, not just put a toxic skull and cross bones next to it.
third page boletus rhodoxanthus edible but rare no need for the skull and cross bones.
forth page boletus calopus the bitter bolete is inedibly bitter again no need for the skull and crossbones.
sixth page pepper bolete edible as seasoning.
ninth page strobilmyces strobilaceus edible but rare. porphyrellus porphyrosporus edible both labelled with skull +crossbones
I will stop there but I hope you are getting the picture.
The skull and cross bones is used whether a fungi is inedible, makes you ill or the edibiliy is unknown, but it is what is writen some other fungi that give me the opinion the book should either attacked with tipex or used as tinder;
stropharia semiglobata has no such skull and cross bones, but it is a well known halucenogenic.
Inocybe geophylla again no skull and cross bones , it is deadly.
amanita virosa well known deady. no mention of this at all.
This is exactly the reason why I bought my other books...
I wanted to know more about how inedible something was as many other books describe, as you have said, edibility when raw, cooked, wether it'll make you ill, severely ill, put you on a dialysis machine, give you cirrhosis, drop you dead on your tracks, 'make you ill, then better, then dead', etc!
Still a handy, cheap, pocket sized guide you can take out on a walk with you (take a few photos and then back to look up what I thought it was from collins in some of the other books I have).
I do agree with you on the edible/poisonous approach though.
