Ascomata: hypogeous to partially emergent at maturity, 3–7 cm in size, subglobose to turbinate, rounded sterile base with a mycelial tuft, whitish at first, becoming light brown, smooth.
Peridium: 200–400 µm thick, well delimited, pseudoparenchymatous, composed of subglobose cells, hyalines and thin-walled in the innermost layers, yellowish and with thicker walls in the outermost layers, sometimes with repent to erect hyphae
Gleba: solid, fleshy, succulent, friable, white even at maturity, with light rose pockets of fertile tissue separated by an abundant, conspicuous white sterile tissue.
Odour: faint, no distinctive
Southeast of the Iberian Peninsula, limited to arid and semiarid areas, in calcareous, alkaline soils, associated with Helianthemum spp., from April to May, sharing habitat with Terfezia clavery.
Terfezia eliocrocae differs in the white, friable gleba, softer than T. claveryi gleba, in pyriform, long-stalked asci, in reticulated spores, 16–18 µm in size including ornament.
Asci: nonamyloid, ellipsoid to pyriform, long or short-stalked, 60–90 x 45–55 µm excluding stalk, walls 1–2 µm thick, with 6–8 irregularly disposed spores, randomly arranged in the gleba.
Ascospores: globose, (15–)16–18(–19) µm diam (median = 17 µm) including ornament, hyaline and smooth at first, by maturity yellow and ornamented with rounded, sometimes truncated warts, up to 2 µm tall and 2 µm broad at the base, forming.a well-developed, small-meshed reticulum, polygonal meshes variable in form and size, 0,5-1 µm thick, 1 µm tall.
