Description: The image shows an amoeba of mayorellian morphotype with striking appendices. Originally considered to be part of the amoeba itself the appendices are de facto part of an ectoparasitic fungus on an infected amoeba. The segments of an appendix being conidia, the round anchoring element within the amoeba being a haustorium. The genus of the parasitic fungus Amoebophilus was erected by Dangeard in 1910 and reviewed by Drechsler in 1959. When first described by Joseph Leidy in 1874 he erroneously considered the amoeba to be a genus of its own and called it Ouramoeba with two species, O. vorax and O. botulicauda. The amoeba shown in the image very much resembles Leidys drawings of Ouramoba botulicauda, with appendices that Leidy described as resembling strings of sausages(Botulus lat.= sausage , Cauda lat. = tail). The putative genus Ouramoeba was also mentioned in Josif Lepsis work on protozoa (1960). This image was provided by Dr. Dr. Josef Brief.
