? on Galium verum

Galium verum, Zwanenwater

the axis of a small part of the inflorescence is galled

higher up in the inflorescence also leaflike elements are included

here the gall also is larger, and multilocular

the galls burst open

parasitised larva; the inner wall of the gall has no mycelial lining
notes
Possibly the gall is caused by Geocrpyta galii, that normally galls part of the stem.
