How can you tell the diff between poisonous mushrooms and healthy ones?

I think poisonous mushrooms have black caps like the death cap. Some poisonous mushrooms have worms on them.

You have to know what breed they are. What breeds are poisinous and which aren't. Their is like a million different kinds of mushrooms and a lot of them look very similar...so watch out. Get a book about mushrooms.

i guess they drift apart according to their colors. you can search on Internet which color indicates the poisonous ones.

People who eat wild mushrooms stick to one or two kinds they know are safe and avoid all the rest.

Get a book, and ASK--ask people who know and are confident in teaching! But one you can always count on is puffballs (as long as they aren't growing on anything poisonous.) If a mushroom is white all the way through and is a big puffy ball, it's a puffball. Taste varies, but it is safe and easy to recognize. I've eaten a few--the giant puffballs are completely delicious, but more rare than pasture puffballs (which are brown on the outside and look a little warty.) Giant puffballs look like big white soccer balls. Mushrooms with caps and pores are easier to recognize, as most mushrooms with caps have gills. These include boletus (porcini) mushrooms and the poisonous ones have weird colors when you bruise or cut them. Get a book--you need pictures and good descriptions. But I've eaten wild mushrooms and I'm still typing!

They aren't, but many that are poisonous look similar to those that are edible... and one should know a little more than what is in a mushroom identification book to pick and eat.... since the consequences are rather.... uh, terminal if you make a mistake

Well, you just eat them like I did, and if you're dead the next day, you got your answer! :) Arum
