Blushing rosette, or Abortiporus biennis to give their official name, is very strange even for a fungus.
They grow on buried wood, and are very variable in form and especially in colour. This can vary from near-white, through yellow and red (hence “blushing”), to browns like this one.
I saw this one (or is it these?) growing on one of the patches of short grass just by an entrance to West Park.
