much more significant and easy to see on the older fb, not really much of any smell that I can tell though

look like S. pungens—any odor? How about dots on stipe? (hard to make out in photos).

hard to see in the picture, but it stayed reddish brown.. Also, one of the characteristics of S. pungens listed on http://www.mykoweb.com/CAF/species/Suillus_pungens.html is milky droplets on the pores of the young fbs, which I hadn’t thought specifically to take a picture of, but you can see a little bit around the stipe in picture #2

Chroogomphus was also within 8 inches of these
