It was asked in a local group of mine about whether or not Morels are fluorescent. They specifically asked about with the Convoy C8 365nm UV flashlight, which I happened to own.

Do Morchella americana/ulmaria fluoresce with a Convoy C8 365nm UV flashlight? Yes.

Does it stand out from the rest of the forest? Kind of a little.

Is it worth dropping $35-$100 on a 365nm UV light? I'm not sure. The fluorescence was pretty close to the same color of wood affected by white rot fungi and some decaying leaves. It's like a pale blue-white fluorescence. So it camouflaged some.

It's hard to say if it helped me or not last night since I knew where these four already were and my light kept dying on me, preventing me from looking extensively for any that I hadn't spotted previously in the day. I also have no idea how Morchella punctipes, Morchella angusticeps, Morchella diminutiva, or Morchella sceptriformis fluoresce at this point.

The bottom line: yes they fluoresce but not in a big way. It might help some, but my data has limitations.
