Notes on the taxonomy and nomenclature of the algal classes Eustigmatophyceae and Tribophyceae (synonym Xanthophyceae)
  • D. Hibberd
  • Biology, Environmental Science
  • 1 February 1981
TLDR
The systematics of the Eustigmatophyceae are revised at the level of species, genus, family and order and Tribophycesae, based on Tribonema, is published as the typified name for the class previously called Xanthophycee.
CYTOLOGY AND ULTRASTRUCTURE OF CHLORARACHNION REPTANS (CHLORARACHNIOPHYTA DIVISIO NOVA, CHLORARACHNIOPHYCEAE CLASSIS NOVA) 1
TLDR
The possibility that C. reptans evolved from a symbiosis between a colorless amoeboid cell and a chlorophyll b‐ containing eukaryote is considered, but the possible affinities of the symbiont remain enigmatic.
Collapse of transient gels in colloid-polymer mixtures
Transient gelation in colloid-polymer mixtures is an interesting but poorly understood non-equilibrium phenomenon which has recently attracted the attention of experiment and theory. In a transient
The ultrastructure and taxonomy of the Chrysophyceae and Prymnesiophyceae (Haptophyceae): a survey with some new observations on the ultrastructure of the Chrysophyceae
  • D. Hibberd
  • Biology, Environmental Science
  • 1 February 1976
TLDR
A model has been constructed which represents the combination of features constructed to be the basic pattern of cell structure in this group and it is suggested that this family should occupy a more isolated position in the Chrysophyceae than at present, possibly in a separate order Pedinellales.
Observations on the ultrastructure of the choanoflagellate Codosiga botrytis (Ehr.) Saville-Kent with special reference to the flagellar apparatus.
TLDR
The structure of Codosiga botrytis is briefly compared with that of sponge choanocytes and collared cells in the Metazoa and some of the possible phylogenetic implications of this are indicated.
Ultrastructure and taxonomy of Paraphysomonas (Chrysophyceae) and related genera 2
This is the second of two accounts reporting on the occurrence and systematics of freshwater species of the colourless chrysophycean genus Paraphysomonas in the Cambridge area, using electron
The Fine Structure of the Colonial Colorless Flagellates Rhipidodendron splendidum Stein and Spongomonas uvella Stein with Special Reference to the Flagellar Apparatus
TLDR
It is concluded that the colorless colonial flagellates Rhipidodendron splendidum and S. uvella cannot be considered as colorless chrysomonads as previously thought or considered to be related to any of the other orders comprising the class Phytomastigophorea.
The taxonomy of Prymnesium (Prymnesiophyceae) including a description of a new cosmopolitan species, P. Patellifera sp. nov., and further observations on P. parvum N. carter
TLDR
A systematic revision of Prym magnesium is given and the taxonomic status of the genus Chrysochromulina in relation to Prymnesium is discussed.
Observations on the ultrastructure of the cryptomonad endosymbiont of the red-water ciliate Mesodinium rubrum
Mesodinium rubrum is a marine planktonic holotrich ciliate of extremely wide geographical distribution which has often been found to be associated with ‘red water’ phenomena (Taylor, Blackbourn &
