Tumuli Shroomaroom is the second full-length studio album from Welsh stoner rock/doom[2][3] band Acrimony.

AllMusic's Eduardo Rivadavia called it "of the all-time classic stoner rock albums ever" and also said that it "makes for remarkably immediate listening, unveiling its otherworldly glories to all those who dare enter the mushroom.

He continued, "Tumuli Shroomaroom might or might not be what Boris Johnson shouts on climax, but it’s also another great underrated gem from the Brit stoner scene.

[8] Simon Young from the same magazine said that while Acrimony is still an underrated band, the album "Tumuli Shroomaroom remains a perfect record to play while firing up that skull-shaped bong".

[9] In November 2019, Tumuli Shroomaroom was reissued as a 3CD digipack and remastered edition by the Dutch music label Burning World Records.
