The photos are good (multiple specimens, cross sections etc),

However:
- his photos in his books are better; they are the

pen portraits, keys etc

Yes. he has the usual problem with Boletus satanas, of course :-)

That is almost universally claimed to be deadly, but evidence for
that is essentially absent. While there probably has been the odd
death, that is also true of many of the poisonous mushrooms NOT
classified as deadly - some people are very sensitive to particular
toxins or otherwise vulnerable. But nobody wants to risk downgrading
it to merely poisonous!

Are any of the non-deadly poisonous ones things that anyone would
actually want to eat, though? (For taste, I mean --- hallucinogenic
ones are of course a different kettle of fish.) AIUI, mushrooms are
generally divided into (1) tasty & safe, (2) dangerous, & (3) neither
--- with the majority falling in the 3rd group.
