Crust Fungus

Waxy crust fungus, Vuilleminia comedens, growing on an oak twig (Quercus sp).  Note that it grows under the bark.

I prepared a slide of the spores using the same technique I used for Peniophora quercina.  The above image (x600) shows them to be bent sausage-shaped and about twice as large as those of P. quercina.  This is consistent with the 'cylindric to sausage-shaped, 18–20 x 5–6um' that Roger's Mushrooms gives for V. comedens.

Specimen collected in Whiteknights Park, Reading, UK, on 2012-12-09.
