All Lactarius spp. with red milk are edible. ;-)
They are actually one of the easier mushrooms to start with at least if you don't care too much about the correct ID on a species level. Kind of like with Russula spp. which are all edible if they taste mild.
But yes, it's better to be safe than sorry. Some are not really tasty in my opinion anyway.
