Chanterelles are the best beginner mushroom to forage. They grow almost everywhere, have only one toxic look-alike (and it's very easy to differentiate), and a very unique color and shape. The defining characteristic of chanterelles is their false gills, meaning on the underside they are either completely smooth or have small ridges that vaguely mimic the typical fanned gills that other mushrooms have. Their color ranges from pale yellow to red (mostly orange, right in the middle) and most have a distinctive irregular vase shape. The way I would describe the appearance is like sheets or curtains billowing in the wind. The only potentially dangerous look-alike is the Jack o' lantern mushroom which only grows in the eastern US, has real gills, and glows in the dark (kinda hard to forget and easy to identify, so eating it by mistake is incredibly unlikely as long as you know about it). I recommend finding someone who has foraged before to go with you the first time, but after that if you stick to just chanterelles you'll be fine.
