A friend of mine has been eating Lepiota rhachodes in volume all
summer long.  He has recently developed a "reaction" to them.  His
mouth gets "tingly/numb" within a minute or so after taking a
mouthfull.  I have known them to have a "laxative" effect on some
folks.  It's alway wise to eat just a small amount of them at first to
test them out.  And DO NOT eat any other kind of 'shrooms with them
for a couple days before OR after.  You will want to have them alone
in your system to make sure that they agree with you.  I've never had
any problems with them.  They are one of my favorites.

The Chlorophyllum molybdites does NOT seem to grow close to the
oceanside areas.  It would be found perhaps 20 miles inland.  This is,
of course, just a rough estimate, but appears to be true in the San
Francisco Bay Area.

As always, be CERTAIN of your identification.  Do a spore print.  Get
to a fungus fair of some sort and look at the differences of the two
species side by side.

And last of all, have a wonderful time with some creative meals.

My very best to all of you,
