ʻO ka ʻeli ʻana i nā pāpū (Buerenia inundata)
ʻO ka hoʻoheheʻe ʻana i ka wai ʻo ka ʻohana Umbelliferae.
Loaʻa ka haʻiki ma ʻEulopa Komohana. Hiki ke loaʻa iā ia ma nā mokupuni Pelekane, hoʻi i Kelemānia, Farani a me Switzerland. ʻO ka manawa mua i wehewehe ʻia ma Farani.
Hiki i ka parasite ke hoʻopili i nā ʻano like ʻole o ka celery, kāloti a me marshmallow.
Ua aʻo kikoʻī ʻia ka pōʻai ola o ka ʻeli ʻana i ka wai i nā makahiki 60-70 o ke kenekulia i hala.
ʻO nā pūnaewele Ascogenous o ka parasite e haki i ka epidermis o ka mea kanu. Penei ke kuokoa ana o lakou. ʻAʻohe manawa hoʻomaha. ʻAʻole lākou i hana i kahi synascus. ʻO ka nui o nā cell ascogenous makua a hiki i 500 µm. Aia ma kahi o 100-300 nuclei. Hoʻokaʻawale lākou i waena o lākou iho e ka meiosis, kahi i hoʻokumu ʻia ai nā ascopores mononuclear. Hoʻopaʻa ʻia nā mea hope ma ka ʻaoʻao o ka cell ascogenous, a ʻo ka vacuole ka wahi i waenakonu.
Loaʻa i ka parasite nā ascopores. Ma mua o ka ulu ʻana, male lākou. Loaʻa nā Ascopores ma nā ʻano male ʻelua e kū'ē ana kekahi i kekahi (ka mea i kapa ʻia he heterothallism bipolar maʻalahi). Ma muli o ka male ʻana, ua hoʻokumu ʻia kahi cell diploid, a laila ulu aʻe i mycelium. ʻO kēia ke ʻano o ke kaʻina o ka maʻi o ka mea kanu a me ka hāʻawi ʻana ma o nā kikowaena intercellular.
