Every year, I get a few butter boletes (Butyriboletus autumniregius) under a grand fir in my yard. This year, I noticed they were coming up, and rushed out to pick them, as they get maggots very quickly. I noticed first that the stems had much more red than usual. Then I turned one upside down, and red pores! My butter bolete site had been usurped by the toxic Boletus pulcherrimus! (Equally delicious to maggots and banana slugs!) However, a week later the butter boletes were up, about 10' farther back in the woods than usual. A good fruiting, too, with a second after this last rain. I've gotten 10 so far. The stem on the butter bolete is stout and reticulate--there's another look-alike with narrower fibrous reddish stipe. They turn a beautiful blue when bruised or cut, then turn back to yellow as you cook them.
