Puccinia cladii

Post by marksteer » Wed Aug 24, 2016 4:29 pm

Looks like this is not so rare - confirmed by Brian Douglas Kew in Norfolk and now in Crymlyn Bog South Wales. 5 hours on Bog (more correctly fen) Monday 22nd August found on Cladium mariscus in boggy woodland and open fen -not easy terrain!
Photo (USBx20) also shows parasitic asco - Eudarluca cariscis (Brian's id). I'm getting out of my depth here not just in Bog!

Great stuff Mark
I must look harder at this Sedge also known as swamp sawgrass, great fen-sedge, saw-sedge or sawtooth sedge or even elk sedge. However, I do find sedges difficult to distinguish between.

Hi Alison, Yes Sedges are difficult for me! 1st time Brian and I went to Crymlyn Bog we were looking at wrong Sedge! Luckily this time we had experts with us. I now am fairly confident with Cladium mariscus and have also checked 2 stands at Kenfig Pool NNR - no Rust on them.
