turns out it is only the mycelium that glows, so your field obsies were spot on!
I was looking for answers yesterday, and found a few.

No, unfortunately not.

Hi Debbie,
No, unfortunately not. Actually I’ve never experienced this phenomenon except once on a heavily rotten wood stump. The wood (mycelium?) was luminescent, not pilei. But I would like, since it seems to me an interesting photography challenge. May be …. some time?

have you ever observed bioluminescence in this species, Amadej?

Yes! Partly also because they were backlit by warm autumn afternoon sunlight. Overall color temperature of the picture can be checked by observing color of tree bark and other objects in the background.

so pink!
