| Rose rust on Burnet Rose. |
Took the dogs around Pembrey Forest today but being quite dry there nothing much on the fungus front to get excited about - except that many of the wild roses growing along the pathways had this orange deposit on them. Checking on the computer it would seem that it is a fungus from the phragmidium genus known as rose-rust, as it is a common fungal infection of rose-type plants.
I've included a picture of the spores because they look so attractive!
The rose is Burnet Rose, Rosa pimpinellifolia, which favours sand/limestone areas so common along Pembrey coast. The rust (help Nigel) is Phragmidium rosae-pimpinellifoliae and some bushes seem plastered but others have the rust here and there.
