I indeed concur, sir Head of Lore.What I suggest we do is the following. We take Myzel's sketch as the basis for all other concepts. This means that we end up with three varieties of trees: my thin one and my huge one and Taijan's medium one (all of which should of course have a few variation models).
Taking Myzel's sketch as a basis, I think we should now concentrate primarily on undergrowth. Preferably that undergrowth shouldn't look awfully much like a toadstool. (Personally I even feel not all of the undergrowth necessarily needs to be fungal in nature.) I think we should be well off with about 2-3 pieces of undergrowth. The rest can be managed with existing flora.
Head of Concept Art, can you agree with this plan of action?
I went through the thread and the following are the images that have some non-toadstool undergrowth concepts. I'm no big fan of any of them and I think we can do better.

Even though these are toadstool-like, I do like the left one:
