Science Notes: Genetic tests have definitely moved this mushroom out of Autroboletus, but where does it belong? Initially it went into Boletellus. Then it got moved to the newly erected genus Heimioporus. Then it got moved back. Then… For those who care, as of November, 2015 the consensus is as follows: (1) There is molecular evidence to support a generic affiliation with either Heimioporus or Boletellus, (2) There is NOT enough molecular evidence to choose between Heimioporus & Boletellus, and therefore (3) we are going to stick with Boletellus betula until more evidence comes along to settle the issue.

Edibility: Good.

CHEMICAL TESTS:

  • NH4OH (Ammonia): No data.
