Just wanted to tie this observation

to another I found recently. It is 91563 found in Colorado. It would not surprise me if the habitats of the two obs are similar. What got my attention was the color of the pore surface and the stipe on the two are so similar. If anyone would like to comment here I would enjoy seeing what others may say. it. 91563 has been vouchered and of course I do not have mine. But they are interesting. I looked at every observation of Chalciporus until I happened to find this old one. Sylvia

that doesn’t seem to fit my idea of Chalciporus is the robust stature, especially the short/thick stipe. Radial arrangement of pores in Chalciporus is not all that unusual, except this feature is fairly prominent for the mushroom seen here.

Cool bolete, Sylvia

The large, angular pores are arranged radially, which is more typical of Suillus, but the pore color, the apparent lack of glandular dots on the stipe, and some bluing of the cut flesh are inconsistent with that genus. Still, I wouldn’t exclude the possibility of it being a suillus. I hope you saved the material.
