Agaricostilbaceae Chionosphaeraceae Crittendeniaceae Jianyuniaceae Kondoaceae Ruineniaceae The Agaricostilbales are an order of fungi in the class Agaricostilbomycetes.

The order consists of six families and 15 genera.

[1][2][3] Agaricostilbales was originally described in 1989 by Franz Oberwinkler and Robert Bauer with just two families, the Agaricostilbaceae and the Chionosphaeraceae.

[4] Molecular research, based on cladistic analysis of DNA sequences, has subsequently added additional families.

Where known, basidiocarps (fruitbodies) are small and stilboid (pin-like).
