About Russula vesca Fr.
The scientific name of this mushroom is Russula vesca Fr. In this species, the cap skin typically does not extend all the way to the cap margins, which is the source of the species' common names. The cap measures 5 to 10 cm across, and can be flat, convex, or have a slightly depressed center. Its surface is weakly sticky, and ranges in color from brownish to dark brick-red. The taste of this mushroom is mild. The gills are spaced closely together and are white in color. The stipe is 2–7 cm long and 1.5–2.5 cm wide, and narrows toward its base; it is white. When rubbed with iron salts (ferrous sulfate), the stipe turns deep salmon. The spore print of Russula vesca is white. Russula vesca fruits in summer or autumn, and grows primarily in deciduous forests in Europe and North America.
