Description:Unexpanded basidiomata epigeous, globose to subglobose, just prior to slightly open, umbonate, 14–23 mm height × 15–28 mm wide, surface rugose with irregular cracks, brown to light brown (5E5 to 6D4, Kornerup & Wanscher 1978), with a few soil incrustations. Expanded basidiomata saccate, 12–29 mm in height (including peristome) × 24–58 mm wide. Exoperidium splitting into 4–10 revolute, triangular and irregular rays, non-hygroscopic. Mycelial layer slightly encrusted with soil at the base, persistent, orange to light brown (KW6A4 to KW6D4) or brownish orange (KW6C3), formed by hyaline to greenish hyphae in 5% KOH, branched, 1.6-3.0(3.9) μm wide, lumen evident, sinuous walls, 0.6 ± 0.1 μm thick. Fibrous layer papery, pastel red to brownish orange (KW7A4 to KW6C3), 1–2.5 mm thick when fresh, formed by hyaline hyphae in 5% KOH, 1.9–4.7 μm wide, lumen evident, branched, straight walls, 0.7 ± 0.1 μm thick. Pseudoparenchymatous layer persistent, glabrous, brownish gray to reddish gray (KW8D2 to KW8B4), cracking at the ray bends and tending to form a pseudoparenchymatous collar around the endoperidium in some specimens, formed by pyriform to oval cells, 19.5–48.0(54.3) μm height × 27.2–58 μm wide, light yellow in 5% KOH, straight walls, 0.6 ± 0.2 μm thick. Endoperidial body globose to subglobose, 8–19 mm height × 10-21 wide, sessile, glabrous, gray to grayish brown (KW5D1 to KW5E3), apophysis absent. Peristome fibrillose to lacerate in age, mammiform, concolor to endoperidium, up to 1-3 mm high, slightly delimited by a grayish white (KW1B1) annulum. Mature gleba powdery, brownish gray to dark brown (KW7E2 to KW8F4). Basidiospores globose to subglobose, 4.7–6.3 μm height × 4.8–6.9 μm diam. [(ẋ) = 5.7 ± 0.5 x 5.5 ± 0.5, Qm = 1.05, n = 30], brown in 5% KOH, densely covered by columnar warts with truncate apex, 0.4–0.6 μm, confluent around the apiculum. Eucapillitium (1.9)2.7–4.9 μm wide, branched, encrusted, verrucose, lumen evident, light brown in 5% KOH, straight walls, 0.6 ± 0.1 μm thick.
