Cladochytriales--a new order in Chytridiomycota.

A new genus and family for the misclassified chytrid, Rhizophlyctis harderi

It is found that this chytrid produces three thallus forms that could place it in three different morpho-genera: Rhizophydium, Phlyctochytrium or Rhizophlyctis, and molecular analyses support its molecularly based phylogenetic placement and its distinctive zoospore architecture.

New taxa are delineated in Alphamycetaceae (Rhizophydiales, Chytridiomycota)

This work analyzes zoospore ultrastructure and LSU and ITS1-5.8S-ITS2 rRNA gene sequences of 11 isolates in Alphamycetaceae from Australia and North, Central, and South America, and delineates two new genera, Betamyces and Gammamyces, each with a distinct Zoospore subtype within the family.

Borealophlyctis nickersoniae, a new species in Rhizophlyctidales

It is recognized that DAOMC 229843, WJD 170 and WJD 171 are representatives of the new species Borealophlyctis nickersoniae, and the phylogenetic placement of the strains within Rhizophlyctidales is determined.

The Polychytriales ord. nov. contains chitinophilic members of the rhizophlyctoid alliance

This order contains Polychytrium, Lacustromyces, Karlingiomyces, two new genera (Arkaya and Neokarlingia) and additional undescribed taxa, which is based on molecular and ultrastructural characters based on phylogenetically mutually supportive characters.

Collimyces mutans gen. et sp. nov. (Rhizophydiales, Collimycetaceae fam. nov.), a New Chytrid Parasite of Microglena (Volvocales, clade Monadinia).

Fungal Systematics and Evolution

Morphology, zoospore ultrastructural observation, and phylogenetic analysis of Zygorhizidium revealed that the two lineages can be distinguished from each other and both possess unique characters among the known orders within the Chytridiomycetes.

Gromochytrium mamkaevae gen. & sp. nov. and two new orders: Gromochytriales and Mesochytriales (Chytridiomycetes)

It is revealed that the zoospore ultrastructure of this strain has unique characters not found in any order of Chytridiomycetes: posterior ribosomal core unbounded by the endoplasmic reticulum and detached from the nucleus or microbody-lipid complex, and kinetosome composed of microtubular doublets.

Phylogeny of Powellomycetaceae fam. nov. and description of Geranomyces variabilis gen. et comb. nov.

A phylogeny supports monophyly of spizellomycetalean chytrids with exogenous development and suggests that multiple distinct lineages exist within this group, and a reevaluation of the ultra-structural features of the two described species supports the recognition of a new family and genus.

Short title: Spizellomycetales A molecular phylogenetic evaluation of the Spizellomycetales

Order Spizellomycetales was delineated based on a unique suite of zoospore ultrastructural characters and currently includes five genera and 14 validly published species, all of which have a…

Kappamyces , a new genus in the Chytridiales (Chytridiomycota)

The zoospore of Kappamyces laurelensis may be the simplest type of zoospores in the Chytridiales, and in a parsimony analysis of large subunit rRNA gene sequences, a grouping of K. laurelense and two other isolates were sister to the core Rhizophydium clade, and both the K. Laurelensis group and the coreRhizophydiales clade had 100% bootstrap support.

Morphology and zoospore ultrastructure of Entophlyctis luteolus sp. nov. (Chytridiales): implications for chytrid taxonomy

This is the first report of a species with monocentric, exog- enous development that has a Chytridium subtype of zoospore, which cannot be considered a homologous character state in all species of the ChYtridiales.

Powellomyces, a new genus in the Spizellomycetales

Powellomyces (order Spizellomycetales) is erected for soil-inhabiting chytrids previously classified in Entophlyctis. Fischer's narrative and figures indicate that Entophlyctis was originally…

Morphology and taxonomy of Entophlyctis confervae-glomeratae (Chytridiales) and related species

It is proposed that Entophlyctis include four species which are saprophytic on plant matter and three species parasitic on algae, and several synonyms are suggested.

Phylogenetic relationships among Rhizophydium isolates from North America and Australia

The range in molecular secondary structure composition and in zoospore morphology suggested that isolates placed in Rhizophydium actually represent multiple genera, and unresolved polytomys indicated molecular divergence among these taxa and the need for a more diverseTaxa and gene sampling to resolve relationships.

An outline for the reclassification of the Chytridiales, and for a new order, the Spizellomycetales

An outline is presented for the reclassification of the Chytridiales into two orders based on fundamental differences in zoospore ultrastructure. The new order Spizellomycetales includes species with…

CAROTENOIDS AND OXIDATIVE ENZYMES IN THE AQUATIC PHYCOMYCETES BLASTOCLADIELLA AND RHIZOPHLYCTIS

In the present study, the presence or absence of carotenoids and a few selected oxidative enzymes in one strain of a chytridiaceous organism has been compared with that in several wild typeand mutant-strains of a blastocladiaceous organism to strengthen the relationship between the Chytridiales and the Blastocladiales.

STUDIES IN THE LOWER CHYTRIDIALES. I. FACTORS AFFECTING PIGMENTATION, GROWTH, AND METABOLISM OF A STRAIN OF KARLINGIA (RHIZOPHLYCTIS) ROSEA

The present paper is devoted to a study of the factors affecting pigmentation and growth of a test strain (Strain 45) of Karlingia (Rhizophlyctis) rosea of chytridiaceous fungi.

Problematical taxonomic criteria in the Chytridiales: comparative morphology of 10 Entophlyctis sp. isolates

The criteria generally used in distinguishing taxa among the Chytridiales are size and structure of the zoospores, sporangium wall ornamentations, discharge papillae and tubes, but a review of the literature reveals that these criteria are not sharply defined but highly variable and unstable for purposes of exact identification.
