Overview
Russulales is an order of the , (which include the agaric genera Russula and Lactarius and their polyporoid and corticioid relatives).
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.1] Basidiospores in this group are typically ornamented with amyloid warts or reticulation 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.[2]

Taxonomy
The Order Russulales is further organized into finer groupings including:
- Family (9): Aleurodiscaceae · Auriscalpiaceae · Bondarzewiaceae · Echinodontiaceae · Hericiaceae · Lachnocladiaceae · Peniophoraceae · Russulaceae · Stereaceae
- Species: ZipcodeZoo has pages for 3,360 species and subspecies in the Order Russulales.
Families
Aleurodiscaceae
Auriscalpiaceae
Auriscalpiaceae is a family of fungi in the order . Like much of the Russulales, it has been defined through molecular phylogeny, and includes physically dissimilar species, such as the tooth fungus Auriscalpium and the gilled, often shelf-like members of Lentinellus. [more]
Bondarzewiaceae
Bondarzewiaceae is a family of fungi in the order . The type species for both its genus and the family as a whole, Bondarzewia montana, closely resembles memembers of Polyporales (and was formerly placed there), but has ornamented spores like those of Lactarius or Russula. This characteristic suggested the relationship between physically dissimilar species that eventually led to the restructuring of Russulales (and other taxa) using molecular phylogeny. [more]
Echinodontiaceae
Hericiaceae
Lachnocladiaceae
Peniophoraceae
Russulaceae
Russulaceae is a of fungi in the order Russulales. Its species have typically friable, chalk-like stalks, that break with a distinct crack, like a carrot but with porous flesh (see below). Microscopically, the cells are not all long thin hyphae, which would provide strength and more fibrous appearance when broken. Instead the flesh contains also many large spherical cells ('sphaerocysts'), which give rise to the macroscopic consistency. [more]
Stereaceae
The Stereaceae are a of corticioid fungi. Taxa have a widespread distribution, are lignicolous or terrestrial (in leaf litter), and typically saprobic. [more]
At least 643 species and subspecies belong to the Family Stereaceae.
