Daylight UV Flashlight Hunting Pictures 3

So I bought a UV flashlight (a UV version of convoy c8 for mineral hunting.)
I went in the forest and went UV mushroom hunting during the daylight. The beam of light is virtually invisible until dusk, but it will make UV reactive things light up any time of day in shadow. More subtle fluorescence in weaker objects need full dark, but I wanted to see what I could find.
I found that only the gills of Crinipellis glowed bright cream, the Entoloma incanum was a very bright green all over. Russulas get VERY bright, and Dermocybe have a shocking saturated fluorescent yellow that the camera could not do justice to.( I think Dermocybe anyway, some old Cortinarius anyway.......EDIT I do not think they are Dermocybe after reading haha, similar textures though, but somewhat bulbous stipe and not bright anywhere). A drab pale pinkish Laccaria turned deep violet purple. A bolete that looked resembled a porcini but lacked reticulation revealed little tiny mildly fluorescent granules near the surface of the stipe that were otherwise undetectable.
Most other mushrooms had very little to no change during daylight. Yellow Cantharellus, Lactarius, and Hydnum all got a wee bit brighter, but stayed near true to the color. The disconnected stipe in the photos belongs to Pluteus americanus, it also has very mild changes unlikely to be noticed during daylight hours
The conclusion is that a 365 nm long wave UV flashlight is now an affordable tool, and should be used as we use other chemical means in the field for differentiation and possibly even during microscopy. A statement on the UV reactivity on the various parts of the flesh of a specimens may prove useful in field identification in the future. The green of the incanum mushrooms was very bright, and I could see teeny tiny pins in the daylight when I could not even see my flashlights beam. A cloudy day or a dense forest canopy would be more than enough shade for daylight hours.

This is great.
Do you know what causes different mushrooms to glow different colours in the UV light?
