Another loner, hidden in plain sight in soil of almost identical color!
Notes/link from my coinciding Mushroomobserver observation below-
Two fused fruiting bodies beneath Douglas fir. Elevation 3,000ft. Within a few inches of freshly blooming Calypso bulbosa occidentalis. Harvested/dried a portion of the smaller specimen for herbarium collection.
In ones and twos at various locations from about 4200 ft to about 5000 ft
Near an Abies concolor that died in the rim fire. Also not far from Jeffery pine and incense cedar.
Found on steep hillside in mixed Douglas fir and white fir forest.
Black oak, big-cone Douglas-fir, ponderosa pine, ceanothus, and incense cedar in the area
Green tinge, no odor. Mild spermatic taste. Near Abies grandis.
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.
