Boletus or Suillus?
Both are polypores and I love Boletus edulis (who doesn't), in our area we have a look-alike that is poisonous (Boletus satanus). The slippery jacks I don't care for as much. Being a hardcore boletevore I am keeping an eye on my favorite patch in my field. Its a little early but we've had some rain already and if we get a good rain in October we'll have lots of boletes in November. It's hard to tell via internet but to me it just looked kind of trumpet shaped, which the other two generally arent. Anyway mushroom season is coming in my neck of the woods, sounds like yours has arrived: biking and mushrooms, what a concept, enjoy!
