I've heard tayberries are very similar to raspberries, but they're longer and have a slightly different flavor. I haven't had any so I couldn't say for sure.
Don't beat yourself up over it. They're easy to miss because they're not in the "main square" of berries, and the color means it kinda mentally merges into the title section. If the poster was designed slightly better, they'd have put darker colored berries in that corner. (Though thinking about it, maybe the order of berries represents the most popular or biggest crop or something.)
