Although I think these are pretty typical for L. spheniscispora, it’d be tough to make the call on a really intermediate collection (say one where the colors were really dark reddish brown but without a discrete central patch) – Else mentions that there are no consistent micro characters to tell them apart.

Thanks Christian

I couldn’t download Else’s paper on L. spheniscispora to check on spore size, etc., and Dimitar’s photos seemed too brownish. However, L. spheniscispora does make more sense based on the other characteristics.
