Ah, mushrooms.... Mushrooms can be many, many things. Even within one specie.
Depending on the specie, mushrooms can be one or more of the following....
a. food
b. medicine (anti-bacterial, anti-biotic, anti-viral, cancer fighting, 15 species!)
c. poison or death on a stick.
d. can be made into hats.
e. remediation of soils with heavy metals, chemicals, or even radioactive material
f. they improve other plants nearby (2x-4x as many vegetables when grown with fungi!)
g. they can be art canvas'. (see Artist's conk as example)
h. Anti-bioweapon active human denial,+ remediation of...
i. They allowed humanity to move in cold weather in primitive times. A hot coal can be carried in some species, without going out or flaming up, this allowed neanderthal age humans to carry fire with them.

Interesting fact, a study was done between Battelle and Fungi Perfecti found that "magic" mushrooms decontaminate Nerve agents like Sarin, VX, and other phosphorus bonded nerve agents(and herbicides, insectisides, etc). During productinon of psilocybin, the mycelium "eats" the phosophorus molecules, rendering the DMMP chemicals non-toxic!!!
So anyway, back to scorpions, mushrooms, and you....
None of the bio-luminescent species contain Psilocybin. (The magic is their glow)
There is a chance that they could be toxic to scorpions. It is a risk. A fairly low one in my humble opinion. But a risk nonetheless. I don't think the scorpion would eat it. Your main concerns are the scorpion "climbing" on them, rubbing their "open" pectines across and absorbing a "toxin", and spore release. I don't think you will have a problem with "pectine rubbing".
So Spores are released by the millions or billions depending on size and specie etc.
Either way, there are a ton of them. You have a few possible solutions to minimize the possible negative effects.
1. You can cut down before spore release.
2. You NEED to have good ventilation.
3. Spores are light and when dry take to wind quickly. When having spore release, use hand held portable vacuum to suck them up. You won't see them going into vacuum though. You just have to have faith that it's working. Conversely, you could add an inch of substrate every week or so, as spores in the sub are not a threat. Only surface and airborne.
A. If you are allergic to mushrooms, this isn't the experiment for you.
B. You are going to have to watch your scorps and yourself, for effects, and adjust accordingly. Mushrooms effect each person differently. You may find it to be too much. This species might irritate you at which point you would have to choose to continue or not.
C. Don't inhale large quantities of spores. They are not generally horribly toxic, but some are.
I think it would be okay. But keep in mind all the above, and watch for "symptoms"
If I had the cash, and wasn't heading out in the desert soon, I would do it myself, I think problems are unlikely,but this isn't a common thing exactly, so you need to watch and use your own good judgement as you go along. Good luck, and if you do it, show us pictures!
