- For other uses, see Gloom-shroom (disambiguation).
As of Plants vs. Zombies 3, he has appeared in three games.
The exact mushroom Gloom-shroom is based on is never explicitly stated, however (like its downgrade Fume-shroom) it does heavily resemble the emperor webcap (Cortinarius archeri), a species of mushroom with bright purple caps that glisten with slime in the genus Cortinarius native to the eucalyptus forests of Australia in autumn.
Its name refers to several definitions of the word "gloom" such as the expression on its face and how it shoots purple fumes in all directions that passes through zombies, and it is a mushroom.

He serves as an upgrade to Fume-shroom which changes his range from a 1x4 area to a 3x3 area, dealing heavy damage towards any zombie he hits.

After being replaced by a plant with a similar ability in Plants vs. Zombies 2, Gloom-Shroom finally returns to his roots in Plants vs. Zombies 3 as an Epic Scrapper plant. Like Plants vs. Zombies, he attacks zombies in a 3x3 area.
- Gloom-shroom had a design prepared in Plants vs. Zombies: All Stars, but has been left unused for unknown reasons.
- He always looks upwards in all of its animation, both in Plants vs. Zombies and Plants vs. Zombies: All Stars.
- Although he does not appear in Plants vs. Zombies: Garden Warfare or Plants vs. Zombies: Garden Warfare 2, an image of him can be seen on the Stickerbook's model in both of these games. This is also true with Sun-shroom and Garlic.
- A similarly designed plant known as Toxic Gloom-shroom exists in Plants vs. Zombies: Garden Warfare 2 as a potted plant.
- It has been proven this plant was originally meant to be the original Gloom-shroom, as a toy exists of Toxic Gloom-shroom using Gloom-shroom's design, as well as a beta icon in-game showing Gloom-shroom.
- Gloom-Shroom is the only plant to appear in Plants vs. Zombies and Plants vs. Zombies 3, but not Plants vs. Zombies 2.
