The megalospheric form produces isogametes (haploid), which by their union form the zygotes (diploid) and, thereby, the microspheric individual is formed, and the two generations alternate with each other. Conjugation is not well established in any species of the family. The specific life cycle of C. balkwilli has yet to be documented, though as in most benthic foraminifera, it is likely to be dimorphic, consisting of a regular alternation between sexual and asexual generations [6, 9, 17–20]. Encystment occurs to tide over the unfavorable conditions and to help in the dispersal of race. The most recent list of confirmed host plants numbers 359 species from 204 genera (Gardi et al ., 2015). Type # 1. podiospores which are growing new megalospheric individuals.
