Micromorphology:

Spores:

4.5-6 x 2-3 µm, cylindric to slightly allantoid, thin-walled, smooth, inamyloid, with one droplet each.

Basidia:

15-30 x 3-4 µm, suburniform, with 1-3 constrictions and one basal clamp each.

Sterigmata:

Four, 3 µm long.

Cystidia:

Capitate cystidia, sometimes a little thick-walled at the base (< 0.5 µm), 4-5 µm in diameter, apical with or without exsudat.

Clamps:

All primary septa with one clamp each.

Hyphae:

Hyphal system monomitic. Subhymenial hyphae, thin-walled, 3-4 µm in diameter, not or strong incrusted with up to 4 µm big crystals, very densely hyphal ramification, subicular hyphae 3-5 µm in diameter, thick-walled (up to 1 µm), loosely hyphal ramification.

Aculei:

Hyphae 4-5 µm in diameter, thin-walled up to thick-walled (up to 1 µm), everytime strong incrusted with characteristical, up to 4 µm big, spherical-formed crystals. Aculeal end hyphae thin-walled, sometimes with secondary septa.
