Although edible, Russula brevipes mushrooms have a bland or bitter flavor. ), and Douglas fir (Pseudotsuga menziesii), often only visible as a raised piece of forest floor; ectomycorrhizal4. [27][28] Some of these compounds have been isolated and chemically characterized from Russula brevipes: russulactarorufin, lactarorufin-A, and 24-ethyl-cholesta-7,22E-diene-3β,5α,6β-triol. lactifluorum [2] In a 2012 publication, mycologist Mike Davis and colleagues suggest that western North American Russula brevipes comprise a complex of at least four distinct species.

Lactarius piperatus has a hot, peppery flavour that makes it inedible for most of us but the parasitic mold does help neutralize the flavour and this combination can make its way to the dinner table. This study undertook quantitative polymerase chain reaction analysis of tissues sampled at different infection stages, to investigate R. brevipes/H. Forms of the mushroom that develop a bluish band at the top of the stipe are sometimes referred to as variety acrior. Spores are roughly spherical, and have a network-like surface dotted with warts.
