I'm reading this as "whenever your mushroom is standing somewhere, it has Efflo around it", and should be as strong as the normal one. This would be huge, and fits the moving mushrooms even more (move the shroom whenever the group moves so you always have Efflo at the group, and can pop it for more healing).
The Innervate change is bad, we'll be back to being a mana battery for healers that need more mana (e.g. discs). Getting more spirit will mean a) we don't need our innervate ourselves any more, and b) we give the priest more mana back. Don't like it.
