When plants rot they emit a gas called hydrogen sulfided. It smells like rotten eggs.

If you had that Japanese guy who caught that big huge world record fish you could have handed him the grass and he would have ate some of it and then told you exactly what the deal was.

Here is the winner. When something decomposes in a low oxygen environment (like say underwater) the microbes that break it down produce hydrogen sulfide. This is the same smell they put in natural gas so that you can detect a leak.
