As it is not an Asco I was not going to post this find but after the discussion about the Pilobolus klenii/oedipus I thought those people who followed that thread might also be interested in this.

Pilobolus heterosporus is described in many of the papers on the group. In most they describe the spores as ellipsoid and almost identical to P klenii but with a greater variation in their size. One says that they are ellipsoid to subglosbose but shows a picture with none of them subglosgose and one describes and shows them with uneven shape and size.

I found this on deer dung and it is a perfect fit for the last of the above descriptions.

I am recording it as P heterosporus but with so many differing interpretations it makes life difficult.

Re : Pilobolus
Good evening Malcolm.

Totally agree with you; the large variety of size and shape of spores sometimes pose problems to arrive at a correct determination. In my opinion, we must observe many and often to better understand this difficulty.
