The fungus forms a rounded ascocarp underground on sandy loam soils. This fruit body remains subterranean for most of the year but breaks the surface in the spring to form a cream-coloured cup (apothecium) up to {{convert|3|cm|abbr=on|frac=4}} wide and tall.

It is likely mycorrhizal, but it is difficult to determine the host species.{{Cite web |title=Geopora arenicola, a cup fungus |url=https://first-nature.com/fungi/geopora-arenicola.php |access-date=2024-03-25 |website=first-nature.com}}
