Ascoma subglobose, narrowing towards the base, medium-sized, 2 to 5 cm in diameter. Initially pale cream in colour, turning brown upon handling or with age, generally with small blackish spots or showing tendency to crack in sun exposed mature specimens.  Peridium thin and poorly delimited, 250-500 µm thick, whitish when cut, pseudoparenchymatous, consisting of subglobose yellowish cells with thin walls, 20-50 µm in size. Gleba fleshy, compact, initially whitish, with small, round, pale greyish areas that become greyish green with age, separated by whitish sterile veins, occasionally with pinkish or salmon-coloured tones, often with small holes caused by mycophagous insects. Intense odour in mature specimens, unpleasant in senescence. Pleasant taste. Macrochemical reactions not checked.

Ascospores subglobose, 16-19 µm (including ornamentation) in diam, hyaline, smooth, uniguttulate, adorned with conical, pointed, fairly narrow and spaced spines, 1-2 µm long and 1 µm thick at the base. Asci generally 8-spored, non-amyloid, ellipsoidal, 50-100 x 50-60 µm.

Habitat and Distribution: Mycorrhizal hypogeous species  originally described from material collected in Albacete, which has subsequently been observed in other areas, but its presence in other Mediterranean countries is not yet known. It is characterized by forming fruiting bodies around the host plant, usually fruiting solitarily or in small groups in Mediterranean areas from mid-February to mid-April, being the first species to fruit in basic soils in the eastern half of the Iberian Peninsula.

Its basidiomata are hypogeous and emerge to the surface at maturity, leaving visible cracks and bulges that allow for collection without the help of trained dogs. It generally appears in open areas and along the edges of paths in forests of Pinus halepensis, Pinus pinaster, and Quercus rotundifolia without the presence of plants from the Cistaceae family, in calcareous, clayey, or even decalcified soils. It has also been found in forests burned two years before, with living pine trees.
