A friend of mine that likes to try wild edibles by sticking them in his mouth, and tasting them, asked me to take a closeup picture of these little beauties. These aren't some he stuck in his mouth,so feel free to identify them...
I am not familiar with American plants, however, this fruit reminds me of that of a spindle tree http://en.wikipedia.org/wiki/Euonymus). If so, your friend was wise not to taste it...
