Reaper's Wineglass

Bubble Mushroom is a flora species found in the Tree Spires.

Appearance
The plant has a long, purple stem that anchors it to the floor. At the top of this stem is a bulging green growth that glows strongly, encased by an irregular purple lattice. Growing outwards from this structure is a thick purple disc that is flattened on the top. Holes seem to be situated at regular intervals around the edge of this disc.

Design
The Bubble Mushroom closely resembles a scaled-up version of the Acetabularia "mermaid's wineglass" algae.
