mushroom (Ghost of a Tale)

The problem is the following.
In the location Far tower", in the forest, collected all the mushrooms (day and night)
but to complete the task, lacking a few pieces.
They grow on a small platform over the cliff (if you stand on the first bridge on the right)
To get to this area is obtained only sragow forward with a second bridge (with height), but as slutty back with her and save progress is not clear.
on the first bridge, though he is near - not doprygnet and falls into the abyss.
what to do with this?
