The rapid solution on my galls on Hypoxylon rubiginosum have encouraged me to this question:


Does somebody know what insect could be responsible for this galls. They are common on Stereum sanguinolentum in the Bavarian Forest (Germany). I suspect it could also be a Diptera.

Hallo Lothar
I am no entomologist, so this may be completely wrong - but see the attachments; perhaps that "lid" in the fourth image might correspond to the "mucilaginous net" in the description . . . . ?

Hello Björn,


I don not remember how I came to this, but I finally named my fotos like this:


Keroplatus testaceus cf. (Mycetophilidae)


Best, Lothar

Hello Chris,


of course, it was one (ore more) of these sources!


But I do not remember what characters brought me to the decision to name this way ...


Thanks again for your help-


and best regards, Lothar
