Fruiting bodies initially closed, spherical, flattened at the base, bluntly pointed at the apex, about 2.5 cm wide, covered by a peridium bearing yellowish mycelial cords over its entire surface; mature fruiting bodies opened, 3.5–8 cm wide.
Peridium four-layered, consisting of exoperidium and endoperidium. Exoperidium three-layered, firm, splitting from the top downward to the middle or ⅔ of its length into 6–8 (sometimes 15) unequal, acute lobes that bend downward and form a "cup" enclosing the endoperidium. The outer mycelial layer is comparatively soft, thin, paper-like, light ochre, sometimes with a faint pearly sheen, soon deciduous. The middle fibrous layer is creamy or light ochre, smooth. The inner fleshy layer is initially whitish-ochre, then brownish, 0.5 mm thick, smooth or cracked and partially deciduous.
Base slightly concave.
Spherical gleba enclosed by the endoperidium, 1.4–2.5 cm wide. Endoperidium single-layered, thin, soft, initially whitish-ochre, then brownish, smooth, sessile, without an apophysis at the base; at the apex it opens by a pore furnished with a low conical, fibrous-fringed peristome, without a ring, sometimes lighter in color and with a shallow depression around it.
Gleba becoming powdery at maturity, light ochre or brown. Columella dense, thin, fusiform, 0.5 cm long, sometimes so soft as to be virtually absent.
