I must heartily disagree withe Helene about mushrooms growing on wood not being toxic. The vast majority of Psilocybin containing mushrooms grow on wood including "laughing Jim" a gymnopylus mushroom often confused with honey mushrooms. While Psilocybin is essentially harmless, the effects can be rather disturbing when they are unexpected. Also, Hypholoma mushrooms grow on wood and on variety is among the most deadly mushrooms in North America. While the "smoky gilled mushroom" is a hypholoma and is considered a gourmet mushroom, it is often found growing side by side with it's lethal cousin on the same piece of wood. Caution and expertise are definitely called for when eating mushrooms.
As for Lucky's comments, The "toadstools" in question are almost certainly amanita Phalloides which results in many deaths each year among Asian immigrants who confuse it with an edible mushroom common in the far east. All amanitas cause liver damage and th potency of the Muscaria and Pantherina mushrooms, used for drug effects, is highly variable. In any case, Amanita poisoning is best treated immediately with milk thistle seed as it seems to contain an antidote not available from modern pharmacies.
Beginning mushroom hunters are best off sticking to morels in the spring and chanterelles and boletes in the fall as thes mushrooms are very easily identified have no known deadly lookalikes.

As a veterinary pathologist, I have seen several cases in which puppies were observed eating toadstools/mushrooms in the yard (presumably Amanita types?), and died within 24-48 hrs.
I can understand why those humans who eat the wrong mushroom often die, or need an emergency liver transplant.  Microscopic examination of sections of liver tissue from affected dogs reveals total death and dissolution of all liver tissue.

Mark,

You are right to preach a conservative approach to mushroom eating as one
should never eat what one doesn't know... especially in the mushroom kingdom.

To my knowledge, there are 5 types of mushroom poisoning, and I won't go
into the details, but the first two types are deadly and survivors (if
caught in time) are left with either kidney failure (dialyses and what not)
or liver problems... The third type comprises psychadelic mushrooms, such as Amanita muscaria. For this mushroom, the mortal dose is apparently 40 lbs for an average adult male. Then there are mushrooms which causes allergic type reaction in
combination with alcool, so with these forget drinking wine, and finally
there are the mushrooms that cause gastros, severe indigestions and
diarrheas. On top of this, many people eat mushrooms that are spoiled, not
fit for human consumption, and therefore get sick for that reason.

Jerry asked for help to identify a mushroom. The edibility of a mushroom is part of the technical description, like taste, colour, size, etc. Since Jerry is wondering whether it is the oyster mushroom which is very edible and highly appreciated by many. So I mentioned the edibility as a characteristic, but not with the intention to encourage him to eat it per se... Most lignous mushrooms (growing on wood) are not toxic but some are not edible because of texture or taste.

I would like to add that you can be an old and bold mushroom hunter, if you apply caution...

No offense meant,

I agree.  I once read accounts of different mushroom poisonings in a
conservation magazine.  What stuck in my mind was the victims could not tell
mushrooms were poisonous by taste, in fact some reported they were quite
tasty.

Some of the cases, victims died, others had to have liver transplants, and
others recovered normally.

The old cliche', there are old mushroom hunters, and bold mushroom hunters -
but no old, bold mushroom hunters.

I am not recommending to eat it, you don't have to read between the line to
figure that out!

Personally, I'd vote against eating a fungus that had been identified only
by sending out pictures, and that had been identified as various different
things by various people on the basis of those pictures. Your risk tolerance
in this area may vary from mine, of course.


Can you find anyone in your area who knows enough about mushrooms to
actually look at a sample for you? Extension office or equivalent thereof,
maybe? If they haven't an expert on staff, they may know who in the area you
could call.

I would vote for Melanopus squamosus, just because it has a foot and a
polyporus grows differently. I have just checked Pomerleau Encyclopedia of
Mushroom (listing some 2000 mushrooms found in Québec) and it has a drawing
of your mushroom and a technical description. It is definitely not an oyster
mushroom because oyster mushrooms have long gills underneath. Judging by the
underside, it will become hard (not rot) and be still there next Spring,
unless an animal eat it while it is still soft. And yes, melanopus squamosus
is edible while still soft, although not recommended for great eating.
Interestingly, there are all kinds of studies being carried out in the world
right now, mainly in Asia, about the medicinal properties of wood mushrooms
such as this one.

This is a wonderful year for mushrooms with all kinds of new entities seldom
seen, appearing everywhere. Thank you for sharing this photo.
