it came by night

It wasn’t here yesterday.  And it might not be here tomorrow.

This was taken about 9.00 this morning.  It’s about 3 inches long and sitting on a bed of slate chippings.  By afternoon, once the sun had taken a good long look at it, it was starting to change.  Turning slightly pink, as if embarrassed at being caught out, the surface is becoming smoother, the pores closing up and forming a thin crust.

No idea what it is.  I expect someone does though.
