An amoeba with the tail ? ID please.

Post by Marek Mis »

Hello. I found this species and I don't know what it is. I can see it the first time. It is quite small. I've done cropping additionally to give it bigger.

Hi Marek,

your image shows the amoeba Mayorella penardi parasitized by the fungus Amoebophilus simplex. I'm quite sure. You can recognize the round anchor-cell of the fungus located in the amoeba, the so called haustorium.

Very nice find Marek.

Martin, why can't the amoeba just expel the anchor? And what is the final outcome?

Hi Marek,

Martin is right! About two years ago, this parasites was presented here and in this thread the history of its identification was discussed.
