Field Notes

Description:

When I turned over this log, this fungus just looked a massive, spreading pore surface. There was very little actual pileus visible. The pore surface was gray, bruised black, and was covered in drops of water. What cap surface I could see was cream-tan and faintly zoned.

Habitat:

Spotted on the underside of a log on the edge of a stagnant pond in a deciduous forest. This fungus is said to have a fragrant odor, but I couldn't smell anything other than the rotten egg smell coming from the pond.

Notes:

Bjerkandera adusta produces enzymes that can degrade polycyclic aromatic hydrocarbons; therefore, there has been interest in researching it for possible use in bioremediation.

I am not experienced enough to give a positive ID, but the gray/blue fertile surface does look a lot like B. adusta's. I'm guessing this is the semi-resupinate form.

Thanks Lisa! I initially thought it was Gloeoporus sp., but when I posted it on the mush ID page, the consensus seemed to go with Bjerkandera adusta. It appears to be a younger specimen, but was large and sprawling. What do you think?

It looks a lot different than the one I found last month (I think mine must have been more aged)! Gorgeous!
