Fungi on dead silver birch

Lots of signs on spring in the woods.  Bluebells are coming along nicely, the new leaves hurriedly photosynthesising before the tree buds open and block out all the light.

But I am still finding great examples of fungi.  And although some people find them depressingly a reminder of death and decay, I am conscious that they have a very significant role to play in the carbon cycle, and without them releasing Carbon dioxide, there would indeed be no new life.

The local woods have a lot of dead birch, and are rich in fungi.

I found a huge specimen of the Razor Strop Fungus, Piptoporus betulinus.  
This was about 30 cm across

This is the Oyster Fungus, Pleurotus ostreatus 

Fomes fomentarius
