Macromorphology:

Micromorphology:

Spores:

7.5-10 x 3-4 µm, ovoid to allantoid, thin-walled (0.5 µm), smooth, hyalin, inamyloid, not cyanophil, with one big or several small droplets each. Spores are glued together to spore balls.

Basidia:

16-23 x 4-6 µm, suburniform with 2-3 constrictions and one basal clamp each. The base of the basidia slightly stalked. Basildial repetition occurs.

Sterigmata:

Four, 4-4.5 µm long.

Cystidia:

Subulate to capitate cystidia, 30-50 µm long, 3-4 µm in diameter, basally somewhat ventricose with several slight constrictions, apically sometimes with a big enlargement. The cystidia are only located in the aculei.

Clamps:

All primary septa with one clamp each.

Hyphae:

Hyphal system monomitic. Basal hyphae 2-4 µm in diameter, thick-walled (up to 1 µm), loosely branched. Subhymenial hyphae 2-4-µm in diameter, slightly thick-walled (up to 0.5 µm), very dense hyphal context with a lot of dead hyphae.

Aculei:

The aculei are built by clustered cystidia.

Habitate and substrate:

Biogeography:

Remarks:

   Aculei formed by slightly ventricose and capitate cystidia...H. adhaerispora
   Aculei formed by sinuose or snake-like cystidia..............H. capitata
Spores shorter than 7 µm........................................H. candidissima
