Etymology.

albobadius (Lat.), refers to the white basidiomata.

Basidiomata.

Annual, resupinate, thin, adnate, without odor or taste when fresh, up to 8 cm long, 1.5 cm wide, and 150 µm thick. Hymenial surface arachnoid, white when fresh and became white to gray when drying. Sterile margin narrow, white, up to 1 mm.

Hyphal system.

Monomitic, generative hyphae with clamp connections, colorless, thick-walled, branched, interwoven, 2.0–4.0 µm in diameter, IKI –, CB –; tissues unchanged in KOH.

Hymenium.

Cystidia and cystidioles absent. Lyocystidia projecting, thick-walled, with a globose tip, some of the globose tips are thin-walled, 38.0–71.0 × 8.3–10.0 µm. Basidia barred, colorless, thin-walled, with four sterigmata, 9.5–14.0 × 4.0–5.0 µm; basidioles in shape similar to basidia, but slightly smaller.

Basidiospores.

Cylindrical to allantoid, colorless, thin-walled, smooth, with one or two guttate, IKI –, CB –, (3.5 –) 4.0–6.0 (– 6.5) × 1.5–2.2 (– 2.5) µm, L = 5.09 µm, W = 1.89 µm, Q = 2.55–2.77 (n = 60 / 2).
