TL;DR: A dichotomous key distinguishes between 83 microsporidian genera and the taxo- nomic characteristics of 87 genera, in alphabetical order, are compared in a table.

TL;DR: The different kinds of kinetids which contribute to the rhabdos and the dorsal brush (presence/absence) are the clue characters for a revised classification of the Haptoria.

TL;DR: Twenty-four soil dwelling testate amoebae, belonging to 34 populations, are described and biometrically characterized and indicate the existence of several geographical races which differ only in their size.

TL;DR: Morphological characters of the vegetative cell (chloroplast structure, cell shape) and differences in the formation of autospores of the cultured strains are described and used to distinguish the phycobionts.

TL;DR: It could be shown that even slight genetic shifts within the range of a monomorphic character can lead to a new shell type (at the height of aperture of Trinema lineare).

TL;DR: In the genus Acanthocystis, as understood until now, three groups of species can be distinguished: species with a centrally attached discoid basal plate, species with an eccentrically attached and incised basal plate and species with two wing-like membranes along the proximal part of the shaft.

TL;DR: An attempt of a new classification is made showing how the structural organization of the dorsal brush might be used to establish 4 subgroups in a future revision of the genus Prorodon.

TL;DR: 13 species of cristidiscoidid amoebae were collected from brackish and fresh waters in Sweden and The Netherlands and two new species are described, 5 species are re-diagnosed, and observations on several previously described species are reported.

TL;DR: The coccoid red alga, Rhodella grisea, was isolated from samples collected at PieStany, Czechoslovakia, in basins with thermal water and is characterized by its wide range of tolerated salinities of liquid media and high production of extracellular polysaccharide.

TL;DR: The morphogenesis of Oxytricha gigantea proceeds in a very similar way to that of other species of the genus, indicating that morphogenetic characters alone are not sufficient for species separation.

TL;DR: The ultrastructural cytology of the microsporidium Duboscqia sidae (Microspora, Duboscqiidae), a parasite of Holopedium gibberum in a Canadian Shield Lake, was investigated using light and electron microscopical methods.

TL;DR: Thecell division is an important character in the filamentous green algae, mainly in the unicellular forms where the cell division is the only modus of reproduction and where with they differ from the un icellular coccoid algae reproducing by sporulation.

TL;DR: Characteristics of shape and measurements of size and number of septa proved to be usable criteria for taxonomy within the genus Raphidiophrys, and 2 different colonial species are recognised.

TL;DR: Construction of an organic shell casing by a species of Difflugia in culture is described from examination by electron microscopy and chemical analysis shows that it is composed mainly of calcium, manganese, iron and phosphorus.

TL;DR: Type species of Cymbomonas tetramitiformis from the Adriatic Sea were found in serial dilution cultures from Golfo di Napoli and studies by electron microscopy revealed the prasinophycean characteristics.

TL;DR: Thirty one different strains of Cyanophytes and eukaryotic algae were immobilized into 2 % agar in tubes and 81% of the strains immobilized in agar proved viable.

TL;DR: The asexual reproductive cells, especially the different types of them, are used as very good and important systematic characters in the green algae.

TL;DR: The morphology and the morphogenesis of a ciliate species inhabiting a soil in Qingdao (Eastchina, Shandong Province) are described and the character of this species is shown and justifies the establishment of a new genus Parabakuella.

TL;DR: A modified silver nitrate impregnation procedure is described, based on the Chatton-Lwoff method, with major differences that the post-fixation in da Fano's fixative is reduced to a single wash and the variability between preparations has been reduced.

TL;DR: The DNA fluorochrome 4′,6-diamidino-2-phenylindole (DAPI) was used to stain the nuclei and other DNA-rich inclusions of 28 species of marine gymnamoebae, demonstrating that the DAPI-DNA complex was often generic and, in a few cases, species specific.

TL;DR: In this paper, Centropyxis gasparella spnovand Parmulina louisi spnovare found mainly in aquatic and wet moss habitats, respectively on Devon Island (NWT), Canada.

TL;DR: In the present paper the following taxa are presented: Syncrypta volvox, the genera Microglena and Conradiella, and Catenochrysis hispida are presented and possibilities for their identification and taxonomic position are discussed.

TL;DR: Pseudostephanodiscus perforatus is a new genus of valve-dwelling crustaceans with irregularly disposed rough chinks instead of radially arranged files of areoles, and a narrow dentate frill on the abvalvar mantle edge of the valve.

TL;DR: A true transverse division in the genus Chlamydomonas was not known up to the present time and there were doubts about it, but now as well a semitransverse as a truetransverse division were found.

TL;DR: A key to the Indian species of genus Myxidium Butschli, 1882 has been formulated and a new species of freshwater fishes is described.

TL;DR: It is thought that the anterior region of the cell is largely occupied by a microfibrillar cytoplasm which surrounds the falcular kinetosomes and which extends posteriad along the somatic kineties in form of bands, which suggests that Opalinids have the cytological organization of a flagellate rather than that of a Ciliate.

TL;DR: Observations on the ecology and natural variability of the species of two green-algal genera, Monoraphidium Komarkova-Legenerova and Koliella Hindak, have been reported.

TL;DR: A protist is described at light and electron microscope levels from the Malpighian tubules of a natural infection of a field cockroach, Blatta sp.

TL;DR: Six species of soil testacea from a spruce forest near Stuttgart, FRG („Edelmannshof“) are biometrically characterized and an “ideal-individual” is constructed for each of these species.
