Yeah definitely deer berry. Not all sparkle berries are bad either! You need to eat a hand ful at once. Here is a patch of some kind of dwarf scrub blueberries close to the coast. It is the first time I have noticed these tiny bushes (the ones inland are bigger). They have small leaves and only grow to a foot or so..
Berries with crowns on the bottom are edible. There are also wild paw paws persimmons red mulberries quince, grapes(ripe now), Chickasaw plum, really good wild pp cactus fruit too
Beauty berry is also edible
