Hydnangium Laccaria Maccagnia Podohydnangium The Hydnangiaceae are a family of fungi in the mushroom order Agaricales.

[2] They may have fruit bodies with stipes and caps (pileate-stipiate), or gasteroid (with internal spore production, like puffballs).

When pileate, the cap is smooth to scaly, sometimes striate, typically orange-brown or violet in color.

Columella (the central, sterile part of the sporangium) may be absent or present, the hymenia are not gelatinized, and are formed in locules.

Basidia are club-shaped (clavate), with two or four sterigmata, sometimes with accompanying cheilocystidia (cystidia on the edges of gills).
