Interesting that this common species apparently hadn’t yet been reported on MO from Point Reyes. They were growing in association with live oak.

Blatantly acrid or latently acrid,

that may to some degree depend on ones personal sensitivity and how big a chunk one chooses to taste test. I’m a minimalist in this exercise and usually take only a tiny piece. Anyway, it would be an interesting group experiment to conduct sometime around a Lactarius display table.

This is the most common mushroom in the woods near me right now. Its extremely acrid, not latent, and always with live oak.

These were more like what Arora noted

in MD about the local variant that is a mycorrhizal mate of oak. I thought the acrid taste was rather latent. And in comparison to the description of Lactarius alnicola var. alnicola in the new “Milk Mushrooms of North America” by the Bessettes and Harris, and MD, they were smaller (caps up to 7.0cm across vs 8-20cm)), perhaps lighter in color, and the latex was not really “scant” but fairly copious and rapid forming.
The spores however do match up in size and ornamentation.
The oak loving variant was not noted in the new book so I guess this name is good enough for the time being.

I found this sp. yesterday at Huckleberry Preserve in the East Bay.

but its incredibly acrid taste was hardly latent. I suspect this is the Lactarius also reported in the East Bay, in abundance, on the BAMS list recently.
