Lieber Arturo,

es könnte eine Arcella sp. sein, vermutlich als Schwebeform wegen der vielen dünnen Axopodien. Eine Aufnahme, in der die Schale besser zu erkennen ist wäre sehr hilfreich.

Liebe Grüße
Regi

Hallo Arturo,
Ja, ich denke es geht in diese Richtung, Arcella ganz sicher nicht wegen der retikulosen Pseudopodien.
Allerdings kennt sich Ferry gerade mit diesen "weichen" Schalenamöben besser aus.
Kannst Du die ungefähre Größe nennen?
Viele Grüße
Martin

Hi Arturo,

You have beautiful pictures as usual, but it is impossible to tell you what kind of amoeba this is without a good picture of the shell or body. It is not a Gromia: these amoebae do have granules on their filopodia. Without further information I guess it could be a Lecythium, Plagiophrys or Chlamydophrys species. Compare yours with:

Chlamydophrys species

Plagiophrys scutiformis

Servus Arturo,

I think it's important to know where this species was found. I guess it is a Lecythium, but I'm not a specialist.  ;)

Kind regards
Angie

Hello Arturo,

Yes, those last pictures make sense, because I recognize the vacuoles at the base of the network. I guess it is Chlamydophrys stercorea; based on several observations I think that Chlamydophrys stercorea is a Lecythium species. Lecythium species are very common, still we don't know much about their taxonomy.

Thanks for the photos!

Ferry
