Hi Janet,

I can tell you it is certainly a Senecio-species. Senecio jabocaea (or Jacobaea vulgaris ssp vulgaris, as it is called nowadays) or S. Do you mean allium ursinum by Crow Garlic? But if it doesn’t look like C. jacobaea, what else can it be? I think it is likely to be caused by a gal midge or a gall mite. Can it be Contarinia aequalis? This seems to be the only left option in Docters van Leeuwen (1982).

Looking forward to see you at Hereford next weekend!

Hi Jojanneke,
It doesn't look like C. jacobaea to me - is the host Senecio jacobaea? I've
not seen it before. It looks a bit like a seed head of something like Crow
Garlic!
Janet
