Rukkhashava Mushrooms are Sumeru local specialties that can be found deep inside the rainforests all over the region. These are character Ascension materials for Collei and possibly others in the future. Rukkhashava Mushrooms are regarded as part of the Greater Lord Rukkhadevata's legacy, hence the similarity in their names.
