Turquoise Elfcup

I was just looking over some photos I took when I was out looking for fungi recently.  And came across these two;

At the time, I didn't know what was causing the blue/green staining in the decaying wood, but it was obviously not man made.

Having done a little research, it appears to be caused by a fungus called Chlorociboria aeruginosa or Turquoise Elfcup.  



Now you may remember that I've posted about Scarlet Elfcup in the past.  They are very common this time of year, but the turquoise ones are harder to spot and are usually around in autumn.  I've certainly never seen them, but I am happy to have found evidence of the unusual fungus!
