What are the hanging mushrooms for in the Super Adventure Box?

So in this months content 'Super Adventure Box' there are a number of jumping mushroom which are at an angle with a green glowing item hanging from them.

When attacked the green item falls to the ground and vanishes and the mushroom drops to being horizontal.

Do these have a use? My first guess was that they were for doing large horizontal jumps.

As explained on the Joystiq guide to Super Adventure Box:

If someone is [...] having some serious issues getting to the checkpoint, look around near you for a mushroom sitting at an angle; shortcut mushrooms have been placed at strategic points along the map to help struggling groupmates catch up. Give it a tap and it should drop a little helper mushroom down to your buddy.

The mushrooms that spawn underneath are the trampoline mushrooms that you can bounce on.
