Rukkhashava Mushroom is an Ascension Material used by several Genshin Impact characters. Currently, only Wanderer and Collei need them. The former is one of the most popular entities in the game, whereas the latter can be obtained for free. This is why knowing where to find this item is incredibly important.
Rukkhashava Mushroom counts as a Local Specialty in Sumeru, meaning that you will only find it within the Sumeru region. More specifically, it's only scattered around the Ashavan Realm and Lokapala Jungle.
Note: You cannot get this item via gardening in the Serenitea Pot.
Since you are required to get 168 Rukkhashava Mushrooms to fully ascend either Wanderer or Collei, you might want to use this interactive map to have an easier time finding them. You can opt to zoom in, zoom out, or pan the map however you'd like.
There are currently 76 spawns for this item out in the wild. That means that you will have to collect all of them, wait for the Mushrooms to reset 48 hours later, and obtain them again to get close to the aforementioned requirement.
You can start at Mawtiyima Forest's northwestern Teleport Waypoint. Collect all of the items located east of there. You can then head south to get the ones at the end. If you haven't gotten the westernmost Mushrooms yet, you can use the Teleport Waypoint south of the previous one to get there.
Generally speaking, the rest of the routes follow a similar format. Find a cluster of this Ascension Material on the previous interactive map and utilize the nearby Teleport Waypoints, Domains, or Statues of the Seven to get to it.
Mawtiyima Forest has the most, which is why some Genshin Impact players might want to prioritize it first.
