Etymology.

minima (Lat.) refers to the type species having tiny basidiomes.

Description.

Fruiting body: Basidiomes subglobose, 5–8 mm in diameter, 3–7 mm in height. Peridium layered: Exoperidium slightly brown when fresh, grayish-brown to fuscous when dry, hymenial surface with coarse granular, not easily falling off, densely grouped on the top of the basidioma; Endoperidium fragile, cream to slightly brown when fresh, slightly brown upon drying. Gleba fuscous, powdery.

Hyphal structure: Exoperidium composed of irregular inflated cells, globose, subglobose, or pyriform, thin-walled, colorless in 5 % KOH, 15–50 (– 90) × (10) 15–32 (– 40) μm. Endoperidium made up of intertwined colorless hyphae, thick-walled, slightly branched, 3–5 (– 7.5) μm in diameter. Capillitium absent. Paracapillitium interwoven and branched, thick-walled, 4–7 μm in diameter, septate.

Basidiospores: Globose to subglobose, 4.7–5.5 (– 6.3) × 4.6–5.5 (– 6.2) μm in diameter, brownish, CB –, thin-walled, ornamented with distinct spines (less than 1 µm), with a short pedicel (less than 0.5 µm), Q = 1.02–1.03, Q m = 1.02 ± 0.02, n = 60 / 2.
