title: Ultrastructure of the asexual apparatus in Mycotypha (Mucorales).
abstract: The development of the asexual apparatus of Mycotypha africana and Mycotypha poitrasii observed by means of scanning electron microscopy is reported. Using ultrathin sections and freeze-fracture replicas, sporangiole structure is described. Sporangiospore structure is compared with that of other members of the Thamnidiaceae.
