Russulales


The Russulales are an order of the Agaricomycetes,. According to the Dictionary of the Fungi, the order consists of 12 families, 80 genera, and 1767 species. According to Species Fungorum, the order contains 13 families, 117 genera, and 3,060 species.
Russuloid agarics represent an independent evolutionary line of agarics, not directly related to the Agaricales.
This group also includes a number of russuloid hypogeous fungi, polypores such as Bondarzewia, some tooth fungi, and club fungi e.g. Artomyces. Basidiospores in this group are typically ornamented with amyloid warts or but a few exceptions are known, e.g. Heterobasidion annosum. The genus Clavicorona was often treated in the Russulales, but its type species, C. taxophila is in the Agaricales. The remaining species are retained in the Russulales in the genus Artomyces.

Genera ''Incertae sedis''

There are several genera classified in the Russulales that are i) poorly known, ii) have not been subjected to DNA analysis, or iii) if analysed phylogenetically do not group with as yet named or identified families, and have not been assigned to a specific family. These include:
