Observation 1920: Lactarius xanthogalactus Peck
When: 2007-01-04
No herbarium specimen

Notes: There was a group of these growing among bay, coast live oak, and a deciduous oak. The latex came out white and instantly turned yellow. I went back today and looked for hairs at the base of the stem, which were present. I photographed a different mushroom, as the original one didn’t show the hairs as nicely. They’re white, with those closest to the top a deep red, similar to the color of all of the mushroom parts. Identified using Arora but not sure I’ve got it right.

This sounds entirely reasonable to me. I saw the pictures of other L. xanthogalacteus and they seemed so much lighter in color, and Arora’s description of L. vinaceorufescens seemed to fit. Anyway, thanks for setting me straight on this.

I have seen actual L. vinaceorufescens on the east coast and it’s noticibly darker (wine-colored) than most of the material we get in California. The most common species this name gets applied due (due to Arora) is L. xanthogalacteus. It’s milk changes in exactly the way you describe. Interestingly, this is a rather dark specimen for that species in California. Without seeing a specimen I wouldn’t be able to be complete confident in the id, but I’d lean towards the conservative and call it L. xanthogalacteus if it were me.
