Crust Fungus

A Stereum sp crust fungus, probably Stereum gausapatum, growing on a log of a broad-leaf tree.

I took the following specimen:

This shows red bleeding where it has been bruised, which is a characteristic of S. gausapatum.

This specimen yielded the following spores (magnification x600, field width 86um):

These are about 8 x 4um which agrees reasonably well with the range of 7-8 x 3-3.5um  given for S. gausapatum at RogersMusrooms.com.

First photo and specimen taken in the Wilderness, Whiteknights Park, Reading, UK, on 2013-12-30.
