galls (?) or slips of insects? - on Hypoxylon rubiginosum (s.l.)

I add here picture of two sites in Southern Gemany. I already had this in different forums but nobody could help me. As here are specialists of Hypoxylon and related fungi, perhaps somebody knows "who" is responsible for this roundish bouildings which I have already found quite often.


Regards from Lothar

Re : galls (?) or slips of insects? - on Hypoxylon rubiginosum (s.l.)
Hi,

they are galls induced by the insect (Diptera, Cecidomiide)Mycocecis ovalis. Quite rare

galls of gall midge Mycocecis ovalis - always (?) on Hypoxylon rubiginosum (s.l.)

Hi Alfredo,


great :-) - I am happy to have this identification.


But I have to contradict - this galls are all but rare, I have seen this many times. Peter Püwert wrote me a mail few minutes ago and stated that they are well-known to him, too.


Best regards from Lothar

Yes, I knew them also but had no idea ...

Here it was already an issue in 2009

Re : galls (?) or slips of insects? - on Hypoxylon rubiginosum (s.l.)
Yes also quite common in Denmark and Sweden. I knew the guy that described the thing in England so I saw the light already 25 years ago :-)
Björn Nordén wrote it up from Sweden sometime back. As far as I remember I have only seen it on rubiginosum s.st.
