Got something to discuss?
Found this a few days ago in Northern Minnesota, USA. I had a very hard time figuring it out, especially since I didn’t bring my Boletes of eastern North America book up there with me. Very beautiful mushroom in person. I normally find Suillus gravellei in that particular tamarack woods but instead were these, maybe due to a particularly wet year. In any case, they were growing both singly and in sequenced clusters from heavy tamarack duff/needles.Has anyone else found it in this area?
Now considered Boletus paluster…..
