the bottom two are box pleating, albeit complex. I read somewhere that to make Floderer's you just crumple a sheet of paper at the center, like you do at the start of his mushroom. Then you crumple small cones out of the big one, and keep on doing that until it looks tree-like. Wet it down, again, like the mushroom, let it dry and voila. Its supposed to be time consuming, but is, in theory, pretty simple. Hope I helped.
