A very old genus,
raised by Vejdovsky in 1881 (Schaeffer,
1926), the type species is A. radiosa
but since has been reclassified on numerous occasions (see for Schaeffer,
1926 for a discussion of the more ancient
literature). Page discussed A. torrei in the context of Mayorella,
yet unlike any other Mayorella, A. torrei produces
cysts. There does not seem to be a uniting feature of the amoebae
described in the genus Astramoeba, save perhaps that they produce
long pointed pseupods but then so do many others.
1926). Freshwater. c50mm
in length while in locomotion. Has fewer than 10 pseudopods some of
which are described as having characteristics between a flagella and a
normal pseudopod. No E.M. study has been carried out and as far as
I know, no cultures of this amoeba presently exit, so the cytoskeletal
components of these structures are unknown. The description given
by Scheaffer seems superficially to resemble the genus Flagellipodium.
Described by several workers but its not certain if they were looking at
the same amoeba.
1926). Freshwater. 25-50mm
in diameter with many blunt cylindrical pseudopods projecting at all
directions. Locomotion uncertain and slow.
