Hyphodontia propinqua

Select illustration:

Macromorphology:

Micromorphology:

Spores:

6-7.5 x 4-4.5 µm, ellipsoid, thin-walled, smooth, inamyloid, with one droplet each.

Basidia:

12-23 x 4-6 µm, young clavate to cylindric, mature cylindric to suburniform, with one basal clamp each.

Sterigmata:

Four, up to 3 µm long.

Clamps:

All primary septa with one clamp each.

Cystidia:

1. Septocystidia, up to 110 µm long, 5-6 µm in diameter, wall 0.5-1 µm thick, apical thin-walled and with an exsudat covering the capitate enlargement. They arise from the subhymenium or subiculum and protude the hymenium up to 50 µm.

2. Lagenocystidia, up to 25 µm long, 4-6 µm in diameter, top incrusted with crystals, which are soluble in 5% KOH solution. They are produced mainly in the hymenium.

Hyphae:

Hyphal system monomitic. Subhymenial hyphae 2-3 µm in diameter, thick-walled (up to 0.5 µm). Basal hyphae 2-3.5 µm in diameter, thick-walled (up to 1 µm), walls pigmented slightly yellowish. Hyphal branching by outgrowing of clamps or subseptal outgrowing
