Yeah, but isn't it true that some species of Aspergillus were long
recognized as making sclerotium-type things, and it was not until someone
opened up one of those developing sclerotium-type things and found asci
that they realized that those sclerotium-type things were cleistothecia?
For that matter, if propagule dispersal is a criterion, how does being
locked up inside a cleistothecium aid dispersal?
Is there any chance that what Kelly has are real cleistothecia, not just
