Lactarius olympianus  Hesler & A.H. Smith (1979)                     *Collections: Pacific Northwest

This is one of the most common milk caps in the conifer forests of the Pacific Northwest. This species bears certain resenmblance to the European species Lactarius zonarius/zonaroides under which name it was known from North America for some time. It is accounted for being very acrid, but in my experience it was mildly so. All American authors state that the milk is unchanging, but it becomes whey like after long exposure and discolors slightly yellow.
