british_galls : Message: My first fungi induced gall

Hello all,

'British Plant Galls' arrived today! Quite appropriate as this weekend I
found my first fungi induced gall on Rosa canina Dog Rose. My new book
tells me that the fungus is likely to be Phragmidium tuberculatum or P.
mucronatum, most Rosa rusts tending to be the former.

Is anyone able to add any more to this please?

Thanks

Richard

PS also found a second Quercus with a small cluster of Andricus curvator
galls.

Hi Richard, P. mucronatum is far commoner, esp on R. canina, (P. tuberculatum is more often on cultivated spp) but you'd need to check details of the...
