Recognized by sight

Recognized by sight: many will show scant milk in dry conditions, or in older fruitbodies. The stature, colors, and staining are pretty much diagnostic for the section

Used references: Arora MDM- pg. 68. “The latex is so scanty as to often be non existent, but the brittle flesh and greenish stains on the cap, stalk and/or gills will identify it.” The only problem with my initial identification was the lack of latex- but according to Arora this is a common occurrence with this species. Also, Christian pointed out the fact that most specimens that are old tend to mostly be latex free commonly.

That was my initial reaction macroscopically when I came up on it in the field. When I found no lactation I was a bit confused. Everything else looked like a massive L.deliciosus- right down to the green staining- just wanted to be sure. Appreciate the info about old specimens/dry weather :) Makes sense.

I’ve usually only found these or very similar Lactarius under pinus on the Washington and Oregon coast in the fall. Love finding a species in far different than usual locations and at different fruiting times. You are an awesome resource!
