Schroederia is a genus of green algae in the family Schroederiaceae. [1] Schroederiaceae is a monotypic taxon; Schroederia is its only genus. [2]

Contents

The genus was circumscribed by Ernst Johann Lemmermann in Hedwigia vol.37 on page 311 in 1898. The genus name of Schroederia is in honour of Ludwig Julius Bruno Schröder (1867–1928), who was a German teacher, botanist (Algology and Bryology), also Hydrobiologist and Zoologist. He worked as a deputy head teacher in Breslau. [3]

Description

Schroederia consists of solitary cells that are needle- or spindle-shaped. They may be straight or curved. The cells end in long spines; at one end the spine may be bifurcated. Cells contain a single parietal chloroplast and one or several pyrenoids. [4] As the cell matures, it develops multiple parietal chloroplasts along its long axis. [5] Cells have one nucleus (uninucleate) when young but may become multinucleate. [1]

Species are distinguished from one another by their overall shape and size. [1]

Reproduction

Schroederia reproduces excusively by asexual means. [1] Schroederia produces zoospores with two flagella, which are released when the mother cell's wall tears open. [1] Zoospores contain a single contractile vacuole and a cup-shaped chloroplast with a single pyrenoid. [1]

Distribution

Schroederia is commonly found in as phytoplankton in freshwater habitats. [4] It has an essentially cosmopolitan distribution, being found in tropical and temperate habitats worldwide. [1]

<i>Micractinium</i> Genus of algae

Micractinium is a genus of green algae in the family Chlorellaceae. Species of the genus Micractinium are common in freshwater habitats. A few species are found as endosymbionts of protozoa, such as Micractinium conductrix and Micractinium tetrahymenae.

Pseudoschroederia is a genus of green algae in the family Characiaceae. It is planktonic in freshwater habitats, and probably has a cosmopolitan distribution. The genus Pseudoschroederia was circumscribed by Eberhard Hegewald and Eberhard Schnepf in 1986. The genus was distinguished from the similar Schroederia by being heteropolar and differing cell structure. However, some authors do not consider the genera to be separate.
