Unicellular desmid with isthmus and two opposing spines on each hemicell. Solid cellulose spines contain no cytoplasm. Staurastrum is similar, but has two or more "arms" (with cytoplasm extending to the terminus of each arm) instead of spines. Freshwater lakes, both planktonic, aufwuchs, and benthic.

There are two groups of Desmids: the " Placoderm " and the "Saccoderm" Desmids. Placoderm desmids have cells composed of two halves (semicells), often almost divided from each other by deep median incisions. The cells are symmetrical about 3 …

2013年1月1日 · We analyzed chloroplast ATP synthetase beta subunit(atpB) sequences from 32 strains of the zygnemophycean green algae, Staurastrum, Staurodesmus, and a single species of Xanthidium.

Definition: An autotroph which is capable of transforming light into chemical energy. Known occurrences, collected specimens and observations of Staurodesmus Teiling 1948. View this species on GBIF.

Unicellular desmid with two rounded semicells with a relatively smooth outline, and supporting spines (cf. Cosmarium). The median constriction or isthmus between the semicells may be narrow or wide. Each semicell contains a green chloroplast. Staurodesmus, Lake Rotoiti, X100. Photo: Thomas Wilding. Found in wetlands and other acidic waters.
