Observation 179266: Trichaptum biforme (Fr.) Ryvarden
When: 2014-09-16
No herbarium specimen

Notes: An extensive “bumpy” crust fungus associated with Polypore caps on an 8" dead log in woods. Probably two different species; a polypore (perhaps Trametes versicolor) and a crust fungus made up of tiny spheroids that seem to coalesce into the crust. Would appreciate help in ID.

2 separate species would be my guess.

Would need to see the spore-bearing surface of the polypore to be certain it was Trichaptum. The crust-fungus composed of “tiny spheroids” is a second fungus. Not sure how Trichaptum arrived at. Could just as easily be Stereum, I would think.

Two organisms or one?

Is the bumpy crust seen here a separate organism than the polypore Trichaptum or is it a separate organism, and if so what is it?

I think you’re right, Bob.

Looks like 2 different fungi here. Stereum or Trametes for the Polypore caps. Crustose fungus for the other.
