The chalky texture of the stipe seen in the cut stem as well as overall gestalt point to Lactarius. Environmental conditions can affect latex production, so the absence of latex does not always mean it’s not a Lactarius. Also, latex production is variable between species, and some species don’t produce much latex. However, a couple small drops of latex are visible in your close-up of the gills. Under the scope, amyloid spores would instantly suggest Lactarius.

thanks for looking at this. As I am learning and tried to key this out please help me understand how you know this is Lactarius.
