Sphagnum bog galerina
books differ whether this is galerina tibicystis or padulosa so I'm going with either or both! Mushroom taxonomy seems to change like the weather. Found this one on the edge of a bog and had to balance on a root so my foot wouldn't plunge through the delicate upper layer. OM 90mm at f5.6 or so.
