I intend to go back and photograph and/or collect when they are older (tomorrow). The fruit bodies were knockout yellow, these were captured with vivid set on the camera and color balanced toward yellow by gimp. But the photos are still not representative. Don’t know if it was the camera or the lighting. Will try flash tomorrow.

These look way too hefty to be L. birnbaumii, not to mention insufficiently yellow, striationless and white at the base. Do you have/could you obtain images of more mature fruiting bodies, or perhaps just a cross-section/underside?

Edit: judging by other NA observations, my concept of L. birnbaumii might be overly tropical. Would still like see some gill shots…
