Hmm, I'm jealous. I've studied really many opomyzid specimens, but sofar never encountered one with Laboulbeniales on it. Laboulbeniales are fungi that occur on arthropods. More common on Coleoptera than on Diptera.
In this case it most probably is
Stigmatomyces geomyzae.
The host in this case is a male of
Geomyza tripunctata.

Hi Jeremy,
Walter Rossi, a specialist in Laboulbeniales, also thinks that the fungus species is most likely
Stigmatomyces geomyzae because this is the only species reported so far on Opomyzidae and because the wall cells of the perithecium are arranged spirally.
Could you add some details on where and when you did collect this specimen?

here's one that's turned up on what looks like a a Sphaerocerid. Would that make it
Stigmatomyces burdigalensis?
