  1. Ian Jenkins says:

    Very pretty fungus, seen in profusion in a Sheffield park.

  2. Birgit Griem says:

    They’re hanging around in mid Norfolk quite profusely too. Such a shame they’re not edible.

  3. Sean says:

    I have found a few of these but i have also found ones that are less destinct and could be Butter/Oak Boletes ( Butyriboletus appendiculatus).
    Both stain blue with red at the bottom of the stem and have yellow pores. I tasted a small amount of flesh and it was not bitter at all.
    Is there a definative way to tell the difference between these two species?

      The Rooting Bolete has bitter flesh.
