Members of the genus have thalli (leaflike photosynthetic structures) that are cyathiform (cuplike in shape.) There are indications that asexual reproduction took place through budding of the thalli.[2] Sexual reproduction also took place, through reproductive structures in stalked outgrowths of the thalli (oogonia and gametangia, the female and male reproductive structures of green algae.)[3]
It is possible that Ivanovia is a taphotaxonofAnchicondiumorEugonophyllum; that is, a characteristic diagenetic alteration of an original fossil organism that lacks taxonomic significance.[7]
