If the cells act as dispersed propagules, then I agree that it
would indicate a degree of functional similarity. Enough to call
them analagous? I guess so.
Another question is the phylogenetic placement of Papulaspora. If
it's aligned with the Plectomycetes, then is it reasonable to
suspect that the papulaspore is a modified cleistothecium? If
it is, then I think we're back in the realm of homology. I
don't know of any molecular or other data on the subject. The
AInsworth and Bisby definition sounds like a young cleistothecium

Wait a minute - is the term hyphenated? :-)
