The genus Tribonema (Xanthophyceae) is a common component of many freshwater ecosystems. It is distinguished by its H-shaped bipartite walls and filamentous habit. Species identification has relied on few morphological characters, especially filament

A transmission electron microscopy study of dividing cells of Ulothrix verrucosa Lokhorst has provided clear evidence that this species differs in many respects from other Ulothrix Kutzing species. These differences include the presence of a microtub

SUMMARY Koliellopsis inundata Lokhorst gen. & sp. nov. (Trebouxiophyceae) is described from periodically flooded agricultural fields in the borderland of Belgium and the Netherlands. This new, unbranched, filamentous alga is typified by relatively lo

In order to fill gaps in the knowledge of the zoospore ultrastructure of the genus Tribonema (Xanthophyceae, Heterokontophyta), the absolute three-dimensional structure of its flagellar apparatus has been reconstructed using transmission and scanning

The morphology and reproduction of Hormidiella attenuata LOKHORST (spec. nova) are described. The ultrastructure of the cell division mechanism and of the flagellar apparatus of the zoospore supports the alga's classification in the Klebsormidiales u

An unbranched, filamentous chlorophycean alga is proposed as a new genus Coccothrix, A single species, C. chlorolobata, is based on an isolate from soil collected at La Gorce Mountains, a remote region of Antarctica about 330 km from the South Pole a

The spatial configuration of the flagellar apparatus of the biflagellate zoospores of the green algal genusMicrospora is reconstructed by serial sectioning analysis using transmission electron microscopy. Along with the unequal length of the flagella
