Phragmidium is a genus of rust fungus that typically infects plant species in the family Rosaceae. It is characterised by having stalked teliospores borne on telia each having a row of four or more cells. All species have a caeoma which is a diffuse aecidium lacking a peridium.[2]
There are a number of species of Phragmidium, most of which are restricted to one or a few host species. Examples include:
- Phragmidium acuminatum on Rubus saxatile
- Phragmidium bulbosum on Rubus fruticosus and Rubeus caesius
- Phragmidium mucronatum
- Phragmidium sterilis on Potentilla sterilis
- Phragmidium potentillae on Potentilla anglica
- Phragmidium rosae-pimpinellifoliae
- Phragmidium rubi-idaei on raspberry
- Phragmidium tuberculatum on some rose cultivars
- Phragmidium violaceum on cultivated blackberry and loganberry
Possibly the most commonly encountered is P. mucronatum, found on most species of wild roses including Rosa canina and Rosa arvensis.[3]
