OK, here is the query as I've worked it out so far, after some thought on my part and modifying it based on your comments.
As to the burnflower and pilfer vine, since I wasn't having any alternates for proposal #1, I'm going to just leave them in there for now. Just because they seem silly from the sentence or two I wrote about them does not mean they can't be made more useful.

and if we really can't think of something, we can always ditch them later.
Mandragora will stay as written in the old MM2, but we can always add to it using mythological sources when/if we write that article.
The carapace and zygom are very similar in the fact that they are infesting fungi that take control over their host. So yes, one should go to alternate status. Though the carapace was notably popular on the polls, the zygom was a more classic critter, and I think that will help the article's acceptance. If you think I'm wrong by making that choice, let me know.
Brown mold and yellow mold have been removed - my bad.

I forgot that they were in the DMG. Noticing that I had left them off the polls for *some* reason I said, "uhoh, better not forget them!"
Guardian tree - we have the quickwood for that already, don't we?
The dusanu does not overlap with the carapace and zygom, since they are in a separate proposal.

besides, that is a particularly popular critter 'round these parts, and I would not want to remove it.
Conaill likes the Faerie Phiz but Shade likes the Bohun Tree... is there room for both in the same article?
Well, any additional comments before I send this one off?
