Trechispora aff. nivea (Pers.) K.H. Larss. View in CoL

Basidiome resupinate, hymenial surface smooth, porulose under the lens, whitish to grayish, hyphal cords present in the hymenophore, margin indeterminate. Hyphal system monomitic, hyphae with clamps, septa ampullate in the basal hyphae and hyphal cords, smooth or encrusted with rosette-like crystal druses. Hyphal cords composed of long-celled and clamped hyphae, encrusted with rosette crystals or smooth. Cystidia absent. Basidia short cylindrical, 8–10 × 3–4 µ m, with 4 sterigmata, and a basal clamp. Basidiospores ellipsoid, 3–3.5 × 2–2.5(–3) µm, aculeate, IKI- ( Fig. 15 View FIGURE 13–16 ).

The specimen is characterized by the smooth hymenophore, small aculeate basidiospores, and presence of druse-like crystals. It seems micromorphologically closely related to Trechispora nivea (Pers.) K.H. Larss. , the latter differing in the hydnoid hymenophore.
