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? Edited by Jan Willem on 13-03-2014 15:06 Jan Willem van Zuijlen |

here's one that's turned up on what looks like a a Sphaerocerid. Would that make it Stigmatomyces burdigalensis? http://www.ispotn...ode/760808 Jeremy |
