The Russulales order contains several families of related fungi, some of which are polypores, coral fungi, toothed fungi, crust fungi and stereums. In other words, there is tremendous variation in the morphology of these various fungi, but they share a similar genetic history. This order is named after and also includes the closely related Lactarius and Russula species, cap and stem mushrooms, which have in common flesh that is so fragile, that they can fairly easily break into pieces due to their unique cellular structure.
