In my favorite mushroom guide, _Mushrooms Demystified",
by David Arora, says:

Shingled Hedgehog:
"Edible, but of poor quality. Many collections have
a bitter taste and parboiling does not necessarily help,
plus it cause indigestion in some people. The European
version is apparently better because it is often sold
in markets there".

I'm not sure why just because it's bitter,
that it should be of poor quality.

We real beer lovers sometimes have been known
to drink beers of 120 IBU (International Bittering Unit);
American style Barleywines, which is like 10 times
the IBU's of your typical Budcoorsmiller.

BTW, I just love hiking with my digital camera.
I can just click away at whatever I feel like.
Especially flowers and plants and mushrooms that
I don't recognize.

Then I can come home and identify them at my leasure.

In fact, a lot of times when I hike, I carry my
plant or mushroom ID book, but I rarely pull them
out and try to ID something.

I think it was because I never liked standing there
on the trail with a book, trying to find out
what something is.

Now I can just click a couple of photos of a mushroom,
and continue on with my walk.

Then when I get back home, I can go through my 50+
shrooming books to figure out what the heck it is.
