Macromorphology:

Micromorphology:

Spores:

5.5-7 x 3.5-4.5 µm, ellipsoid up to ovoid, thin-walled, smooth, inamyloid, with one droplet each.

Basidia:

16-22 x 3.5-4.5 µm, young clavate, mature suburniform, with 1-2 constrictions and one basal clamp each.

Sterigmata:

Four, 3 µm long.

Cystidia:

Capitate cystidia, 20-60 x 4-6 µm, thin-walled. They arise from the hymenium, subhymenium or apex of the aculei. The cystidia are incrusted with a coat of crystalls, which are not soluble in 5% KOH solution.

Clamps:

All primary septa with one clamp each.

Hyphae:

Hyphal system monomitic. Basal hyphae 2-4 µm in diameter, thin-walled, in direction of the substrate more or less parallel running. Subiculare hyphae 3-5 µm in diameter, thin-walled, strongly incrusted with crystals, loosely hyphal running. Subhymenial hyphae 3-5 µm in diameter, very strongly incrusted with crystals, densely hyphal running. The crystals incrusting the hyphae are not soluble 5% KOH solution. In the hymenium there are many collapsed basidia present. Hyphal branching by subseptal outgrowing or outgrowing of clamps.

Aculei:

Hyphae of the aculei 3-5 µm in diameter, thin-walled, very strongly incrusted with crystals. Hyphal endings of the aculei thin-walled, obtuse, slightly subulate or with capitate hyphal endings. The aculei are steril. All crystals era not soluble in 5% KOH solution, Eau de Javelle and Lactophenol.
