Observation 65130: Lactarius substriatus A.H. Sm.
When: 2011-03-12
Herbarium specimen reported

Notes: The latex turned light yellow by the time we got to the car. Unfortunately, I did not photograph the change.
Similar species considered were L. luculentus which has white latex that stains areas brown, and L. subflammeus which also has white latex, but does not change colour.

Totally worth the effort.

Good question. I think some species, some times, and more likely when they are young. After this I wanted to test it out more often, but it has been a bit dry… Did see a few L. rubidus and more of these L. substriatus when we were out Saturday, but I didn’t remember to check for this.

Are there a lot of lactarius sp. that will produce latex in the stem if provoked?

Oh yeah…

I forgot to mention that I did not find the mushroom like this… I spent a while pricking the stipe with a pine needle while walking along the trail.

Wow, very cool!
