Macroscopic features
The closed tuber has a diameter of 3–5 cm, fully opened from the tips of the lobes a diameter of 5–10 cm. The spore sac measures 2.5–4 cm in diameter. The outer shell ( peridium ) of the bulbous, coarsely scaly, sessile fruiting body tears open into four to eight pointed tips that bend back and release the sessile, creamy white, approximately spherical spore sac that sits on a fleshy collar . Its outer skin is paper-thin, at its upper end sits the pore that releases the spores and is surrounded by a ring-shaped, pale field. The spore mass is initially firm and pale, later it becomes powdery and dark brown.
Microscopic features
The spores are round, warty, and 3.5-4 micrometers wide. The basidia are 2- to 4-spore, the sterigmata up to 20 µm long, cystidia are absent.
Ecology and phenology
The ruff earth star is found scattered in deciduous forests, occasionally individually, usually in small groups on the ground or in the leaves. It colonizes limestone soils in open spaces.
Fruit bodies are found from summer to autumn.
