There are many different color combination, a lot of them are edible caps and boletuses, but others are extremely dangerous, best to do your own research, maybe even buy a mushroom book guide.
Even after over 20 years of experience, I often do the 3 basic tests :
visual (it looks right, doesn't change color
smell (( it has to smell good )
& it's quality (I tapp them on top to feel it's strenght, so I know it isn't too old, before I take it)

Also, always clean the mushroom in the woods, cut it, instead of pulling it out, so it may grow in the same place again :)

raaawr!
