    Identification difficulty

    It is found on Alexanders (Smyrnium olusatrum)

    When to see it

    Spring and summer.

    UK Status

    Most records come from the coasts of England and Wales, but as the host plant moves inland, sometimes along salted roads, the rust fungus may be expected to occur more widely as well.

    VC55 Status

    Infrequent or under recorded in Leicestershire and Rutland. The Burbage Wood record of 25th March 2016 is believed to be the first confirmed record for VC55.  However the host plant, Alexanders is spreading in our area and Puccinia smyrnii may well turn up more frequently.
