Reishi

is the main component material of Souls and all spiritual matter.

Overview
Reishi composes the spiritual bodies of Souls, including Hollows and Shinigami, and everything in Hueco Mundo and Soul Society. Reishi is invisible and intangible to mortals, with the exception of spiritually aware ones such as the Quincy or Fullbringers.

There is also a certain amount of Reishi in the Human World. Free Reishi tends to be found in places closer to nature. Quincy collect this Reishi to use for combat in the form of Spirit Weapons. Reishi in the atmosphere is also able to be controlled freely, allowing a person to gather it under their feet so that they can stand on air. In Soul Society, for most Souls that die, their entire bodies and clothes eventually degrade and become the very Reishi that makes up Soul Society.
