Hello

A dozen of Mycetophilidae flying around a young group of Pleurotus ostreatus. Sometimes landing, to lay an egg, I presume
My pictures "in situ" are not good.
But I've picked the mushrooms (of course), and one (not too damaged, though a bit crushed) of these gnats

I believe this is one of the Mycetophilinae subfamilly (Am I wrong?)

I used this document to try to go to genera.
From the 65 characters listed, I've only checked 18:
4, 16-18, 24-32, 39, 52, 54, 58, 60

Only one genera almost fully matches these characters : Allodia (at least 3 or 4 non matching for other genera)

The only non matching character for Allodia is:
M stem (0) weak; (1) distinct
I may have misunderstood the meaning:
It seems distinct to me, but it's weekier than the veins above it...

I'm not at ease with the thorax side parts. The last 3 pictures may help, I guess... but don't help me much!
