What is it I am looking at here?

These photos are taken from a Strobilurus found 22nd April 2010.
The first photo is material from the gill. Is the large body a cystidia? What are the smaller round bodies? (nb. I am not sure of my calibration)

The 2nd photo is material taken from the stipe. I am interested in what I am looking at and particularly what the body is outlined in red.

Let me respond about the top photograph. The large pointed cells are cheilocystidia (i.e. those that occur on the edge of the gill as opposed to the face). You will note that they have pointed ends. They are thus 'fusiform' and this shape allows you to key the species to [i]Strobilurus tenacellus[/i] because other Strobilurus species have differently shaped cystidia. The rounded cells are merely undifferentiated cells of the gill. The Strobilurus genus is not that widely described in the literature, but are to be found in Flora Agaricina Neerlandica Vol 4

Hope this helps
