Similarity of Amphoromorpha and Secondary Capilliconidia of Basidiobolus

Abstract
The life cycles and relationships of a variety of minute fungi occurring on arthropod integuments are poorly known. Species of Amphoromorpha Thaxter are reported from all continents except Australia and Antarctica on arthropods and mucoralean and laboulbenialean fungi. Based upon observations of herbarium specimens and of mites and termites exposed to cultures of Basidiobolus ranarum Eidam, we conclude that species of Amphoromorpha actually may be the secondary capilliconidia of Basidiobolus spp. Evidence was obtained from morphological similarities of attachment region on the arthropods, shape and method of internal cleavage of the conidia, and opportunity for attachment of conidia to arthropods and fungi in their habitats. Secondary capilliconidia of Basidiobolus appear to be important for disperal to new substrates in the life cycle of these fungi.
