ID needed

I've looked all over the place and I cant seem to ID these. Any Ideas and are they good or bad? (the green things, I know about the Coraline)
 
I have them too...i started with one and i have about 10 now.

here's and id from marc's page:

That's odd. I looked right at the ID on Marc's page and thought, "no, these are just one or 2 spots, not a cluster" and dismissed it :oops:
I think as it stands now I have maybe 15-20 stalks. Might be time to prune.
