Type-studies in American Russula subsection Decolorantes (Russulales, Basidiomycota), part II.

Abstract

In this second contribution on native American species in Russula subsect. Decolorantes, the authors focus on four additional species that exhibit a blackening context: two species from the West Coast, R. californiensis and R. occidentalis, and two species from the East Coast, R. rubescens and R. rubriceps. A key to the species in Decolorantes is provided. Russula californiensis and R. rubescens are lectotypified.
