Analagous? By definition, no. Cleistothecia are structures in which
ascospores form, and fungi that produce ascospores are not deutero-
Homologous? Perhaps. It has been proposed that Aspergillus sclerotia
(like those produced in A. flavus) are derived from cleistothecia.
Aspergillus sclerotia vary a lot structurally, but none produce
spores. If cleistothecia and sclerotia do not share a common
evolutionary origin, then in a sense they may be analagous, because
both may be important agents of resistant dispersal. But I think that's
going out on a limb.
