It is a fornicate species of earthstar, meaning that the tips of the rays press down so as to raise the spherical spore sac into the air.

Based on the characteristics of the exoperidium (the outer tissue layer of the peridium), Geastrum jurei is classified in the section Perimyceliata Stanek.

Although the species G. dissimile appeared to be related, Lazo examined the type specimen, and proved it to be different not only by a more sulcate mouth (with deep narrow furrows or grooves) but also by other macroscopic and microscopic characters (e.g., smaller spores with acute spines).

The outer surface is strongly encrusted with sand and debris; the fibrillose layer is hard, on the outside shining, pale ochraceous, on the inside chestnut.

The peristome is roughly conical, silky, slightly radially wrinkled (but not sulcate), and very pale grayish brown.
