October 04, 2003, Ozhigovo station, Naro-Fominsk district, Moscow region.
I think that these galls were formed by larvae of Agathomyia wankowiczii (Platypezidae) on Ganoderma applanatum (= G. lipsiense), host tree probably was Tlilia cordata.

There's a link to an article about this fly:
Eisfelder I, Herschel K (1967): Agathomyia wankowiczi Schnabl, die Zitzengallenfliege aus Ganoderma applanatum, Westf?lische Pilzbriefe Band 6. (http://wwwuser.gw...Bd_6_2.pdf).

Nice, I am studying this species and all flat-footed flies and be sure that it is A. wankowiczi. But It looks like the fungi on your pictures was infested previous season, new galls looks different. And the end-holes on the firts two pictures are too big, I am experienced with smaller ones. I can show you my pictures if you wish. The article is fine. I have many others, but only on paper Sad, not in pdf.

I've found some Ganoderma applanatum with galls this autumn, including one on Betula (Sept. 08, Zosimova Pustyn station, Naro-Fominsk district, Moscow region) where the galls looked pretty fresh. Since the adults will hopefully emerge only next spring, I decided to check whether anybody's home. I opened a single gall (random choice) and there it was, looking very much like on pictures in Chandler (2001, p. 133, Figs 150-153).
First, the galls again.

And now the larva itself. Size 4.5 mm. Unlike most known Platypezidae larvae, it lacks marginal and dorsal processes on body segments (together with Nearctic Melanderomyia kahli which feeds on stink-horns, Phallaceae; in others, these processes can be very reduced as in Seri obscuripennis). Note the elongated tubes which carry the anal spiracles.

I also found the larvae of Agathomyia wankowiczii; 17.10.2007, Brno - Reckovice, Moravia, Czech Republic; The living larvaes were in the galls, so I took a scalpel and look if is anybody at home Smile And it really was. I have the photo, but the Black's photo is better Wink, but maybe it will be useful to see the place where I found it.

And, now detail of the fungus. Note: it's not so strongly affected/infected with the galls.
