removed bad hint that the quest is relevant (not true) and bad guidance (the quest is actually a bad one to select) and that it won't spawn in adventure mode (it will)
The '''Black Mushroom''' is a reagent for the [[Staff of Herding]] which grants you access to the secret level [[Whimsyshire]].
This item is found in the [[Cathedral Level 1]] in Act I. It doesn't always spawn but if you want to farm for it at the '''Select Quest''' menu , take [[A Shattered Crown]] quest option. This will put you in Tristram. Take the [[Waypoint]] to the [[Cathedral Garden]] and take the nearby entrance to [[Leoric's Passage]] and from there up the stairs to [[Cathedral Level 1]]. Simply explore that level, rinse and repeat.
