L. rufus

Upon further examination, it appears that the cap is not concentrically zoned. Thus one would have to agree with Doug and call it L. rufus, which fits well with the habitat it was found in.

IF olympianus, then the gills and stipe should stain brown…

and the spores will be partially reticulate. It’s an oddly shaped and colored rufus, tho…w/out further work-up, this should prob. go to Lactarius sp.

There are some more facts to get down here, like is the cap or stipe viscid? Did the latex stain the gills in any way? I think, looking that things here, and assuming that the cap isn’t really viscid here, and I don’t see any staining on the gills, perhaps the a better name here might be L. rufus. Which is found in the area there under pines.

After sitting at room temp for 10 hours, the latex is still white.

Are you sure here….

Are you sure about the white unchanging latex here? It can take some time, esp. if the mushroom is cold. Try warming up the latex with your breath, or letting it sit at room temp for awhile. Darvin has found some that he named from up there, where the latex didn’t change until the next morning.
