The wowhead page about the [Mushroom Chair] (http://ptr.wowhead.com/item=70161) has been updated with the following info:
"This item is available after completing both the Druids of the Talon quest and the Shadow Warden quest
The NPC who sells this item and many others is
Ayla Shadowstorm <Treasures of Elune>
This item can only be bought after completing the "Filling the moonwell" 125 mark quest.
It has a cost of 400g"
I'm not on the PTR, so can somebody go and confirm that its there?
I need a 2nd fishing chair ;)
