Butteucite is a complex mineral deposit. Heavily fossil-ridden, it has an average metal content of 62%.

The mineral was first discovered by the Loranche Somarinoa on the planet Litvaardpa Dummi.

Superficially, it looks like a large fungal tree, like those seen in the various Fungiferous Forests across the universe; however, they are in actuality layers of detritum formed from layer upon layer of sediment compressed over hundreds of millions of years. They consist primarily of ground up shells of extinct organisms that once inhabited a planet-spanning ocean. Hard wearing from various erosive techniques has led to their unique shape, which appears to form an almost tree-like stalk and several tablet-like "caps" that give it its mushroom-like appearance. As they are more compressed in comparison to the surrounding landscape, the substrate is blown away and leaves the Butteucite itself behind over time.

Studies have recently begun on the fossils found within the confines of Butteucite to understand what species of shelled organisms make up the mineral.
