Observation 212888: Lactarius scrobiculatus (Scop.) Fr.
When: 2015-07-21
No herbarium specimen

Notes: Found in soil at an elevation of about 10,000+ feet on Winsor Trail. Mainly conifers present. This specimen was so covered with soil it had to be “cleaned” quite a bit to get a decent photo. Photos not taken in situ, but later in another location. Any other ideas as to identification welcomed.

How wonderful for you to point out another possibility. I think you’ve hit it on the head! Had never heard of either of these Lactarius species. Saw this a few weeks ago on a trip and have been searching for an answer. Don’t recall how I saw the observations of L. repraesentaneus, but I was sort of doubtful because of the cap margin. I am now looking at observations of the name you proposed. Certainly seems to be it. Thought the potholes to be so distinctive. Thanks again. Sylvia

L. scrobiculatus is another possibility. It has yellow staining latex as opposed to the violet staining latex of L. repraesentaneus. It is also very acrid and typically has a sparsely tomentose cap margin, whereas L. repraesentaneus is mild to slightly acrid, and typically has a densely bearded cap margin.

I’m more inclined toward L. scrobiculatus on this observation, mainly based on the cap margin.

Nice find!
