Etymology.

tomentosa (Lat.) refers to the tomentose exoperidium surface.

Description.

Fruiting body: Basidiomes pyriform and subglobose to globose when dry, 5–8 mm in diameter, 6–10 mm in height. Peridium layered: Exoperidium sulphur-yellow when fresh, buff-yellow to orange-yellow when dry, with densely arranged tomentose structures, not easily falling off. Endoperidium fragile, white when fresh, off-white when dry. Gleba white, powdery, or fibrous.

Hyphal structure: Exoperidium composed of chains of inflated cells, ellipsoid to oblong, thin-walled to slightly thick-walled, colorless in 5 % KOH, 25–40 × 15–25 µm. Endoperidium made up of colorless hyphae, thick-walled, occasionally branched, no septa, 2.5–4 μm in diameter. Capillitium of Lycoperdon - type, branched, thick-walled, no septa, 3.5–5 μm in diameter. Paracapillitium composed of chains of colorless, inflated cells, 2.5–5.5 μm width.

Basidiospores: Globose to subglobose, (3.3 –) 3.5–4.8 (– 5.3) × (3 –) 3.2–4.5 (– 4.8) μm, CB +, ash-gray, thick-walled, with distinct spines, with a long pedicel (1.0–6.5 μm), Q = 1.06–1.07, Q m = 1.06 ± 0.09, n = 60 / 2.
