The fruiting body of S. cepa is considered gasteroid, meaning that the spores are formed and mature internally.

The fruiting body consists of spore-bearing substance called gleba surrounded by a protective layer known as the peridium.

The fruiting body can be found fully buried, above-ground (epigeous), or partially exposed.

It can occur in sparse grass, woodlands, landscaped areas, or on disturbed ground.

[4][5][3] S. cepa has worldwide distribution, and is especially common in North America, Europe, and Australia.
