Thanks for your help. Tough to tell from my pictures with the lower, interior part of the stem having some yellow, and the majority of the outer stem being pinkish. Mark

These two are twin like and possibly indistinguishable from field characters. One difference is that C. pseudorubinellus has yellow basal mycelium which C. rubinellus lacks. I can’t tell from these pictures about that feature. And is that significant? Probably not that many collections have been examined. C. pseudorubinellus also has smaller spores and as far as known a more northern distribution. Again how many collections have been made? If you have Bessette & Roody’s North American Boletes these two are described and illustrated. The pics show C. rubinellus with a red stem and pseudorubinellus with a yellow stipe. If you do not have this book you can read about them at this link if you can get it to work. http://books.google.com/...

Thanks Walt and to others..

Walt, Would you please add a comment about what might make this C. pseudorubinellus vs. C. rubinellus. Thanks, Mark

To separate from C, pseudorubinellus. C. rubritubifer, according to Bessettes and Roody is known from only one state park in Florida.

Thanks Charles

I agree. This is the only one I’ve seen so far. Easy to miss at this small size. Mark

Much thanks for taking your time to help identify this tiny bolete. It certainly looks like the correct I.D. from a macro level. Mark
