Verification of morphological diagnostic features and the establishment of three epitypes for three species of Phacus Dujardin—Phacus pleuronectes (O. F. Müll.) Dujardin, Phacus orbicularis Hübner, and Phacus hamelii Allorge et Lefèvre—was performed based on literature studies and analysis of morphological (cell shape, cell size, and periplast ...

FINE STRUCTURE OF PHACUS SPLENDENS POCHMAN (EUGLENOPHYTA)
Journal of Phycology, 2000The general fine structure of P. splendens Pochman (Section Pleurapsis) is described. This Section comprises a series of species with very distinctive features unshared by the majority of the members of the genus. The cells are pear‐shaped in frontal view, rounded at the anterior end, narrowed posteriorly tapering in a long twisted tail.

The Euglenophyceae chloroplast was acquired when a heterotrophic euglenoid engulfed a green alga and subsequently retained the algal chloroplast, in a process known as secondary endosymbiosis. Since this event, Euglenophyceae have diverged widely and their chloroplast genomes (cpGenomes) have as well.

ULTRASTRUCTURE OF THE RESERVOIR AND FLAGELLA IN PHACUS PLEURONECTES (EUGLENOPHYCEAE)1
Journal of Phycology, 1975SUMMARYThe ultrastructure of the reservoir region of Phacus pleuronectes is described. Thin sections, ruthenium red staining, and shadow‐cast preparations elucidate relationships and structural details of the flagella and flagellar hairs or mastigonemes.

Evolution of Distorted Pellicle Patterns in Rigid Photosynthetic Euglenids (Phacus Dujardin)
Journal of Eukaryotic Microbiology, 2009ABSTRACT. Members of the euglenid genus Phacus are morphologically differentiated from other photosynthetic species by the presence of a rigid cytoskeleton (pellicle) and predominantly dorsoventrally flattened, leaf‐shaped cells. In order to better understand the evolutionary history of this lineage, we used scanning electron microscopy to examine ...

Although Phacus longicauda is the type species of the genus Phacus and one of the most common species among autotrophic euglenids, its correct identification is nearly impossible. Over 30 morphologically similar taxa appear in the literature, but there are no good diagnostic features to distinguish them.

Abstract Twenty-one species, belonging to the genus Phacus, were identified during the study of samples from the central region of Portugal collected in lentic systems. The abundance of each taxon was determined. Water samples were taken for determination, by means of standard methods, of physicochemical parameters (water temperature, pH, organic ...

EVOLUTION OF PHACUS (EUGLENOPHYCEAE) AS INFERRED FROM PELLICLE MORPHOLOGY AND SSU rDNA
Journal of Phycology, 2001This research integrates a large morphological data set into a molecular context. Nineteen pellicle characters and 62 states from 13 euglenid taxa were analyzed cladistically. The pellicle morphology of Euglena tripteris (Klebs), Lepocinclis ovata (Conrad), Phacus brachykentron (Pochmann), P. oscillans (Klebs), P. pyrum (Stein), and P.
