Macromorphology:

Micromorphology:

Spores:

5-6.5 x 4-5.5 µm, wide ellipsoid to subglobos, thin-walled, smooth, inamyloid, with one droplet each.

Basidia:

18-24 x 5-7 µm, suburniform, basal strongly ventricose, mostly with one median constriction and one basal clamp.

Sterigmata:

Four, up to 3.5 µm long.

Cystidia:

1. Thin-walled cystidia, basal ventricose, apical subulate up to cylindric, up to 50 µm longe, basal up to 8µm wide, thin-walled cystidia.

2. Thin-walled cystidia, basal ventricose, apical capitate, up to ca. 50 µm long, basal up to 6 µm wide.

Clamps:

All primary septa with one clamp each.

Hyphae:

Hyphal system monomitic. Basal hyphae 2-4 µm in diameter, slightly thick-walled (up to 0.5 µm), hyphae loosely running, some hyphae are incrusted with little, up to 2 µm long, tablelike crystals. Subicular, subhymenial hyphae and hyphae of the pore walls 2-4 µm diameter, thin-walled. Hyphal branching by subseptal outgrowing and outgrowing of the clamps.

Pores:

Hyphae of the pore walls parallelly running. Hyphal endings in the pore margins thin-walled and sometimes incrusted with little, up to 2 µm long, tablelike crystals.

Habitate and substrate:
