Can anyone identify this unknown from just this picture and the fact that this stuff smells really bad? Not a good example of a streak plate, I am just learning to do this stuff on my own. Thanks!

P.S. If you can't identify, what key characteristics would you use to describe it? I feel very unsure of myself when describing these so far.
