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 propensity for soil habitats. We generated DNA sequences from small (SSU), large (LSU) and 5.8S ribosomal subunit genes to assess the monophyly of all genera and species in this order. The 53 cultures analyzed included isolates on which all described species were based, plus other spizellomycetalean… 
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.
Thoreauomyces gen. nov., Fimicolochytrium gen. nov. and additional species in Geranomyces
A linear discriminant function analysis of thallus characters was not completely accurate in assigning chytrids to the correct genus or species, thus emphasizing the importance of molecular characters for identifying these taxa.
Fayochytriomyces, a new genus within Chytridiales
The morphology of culture WJD186 is consistent with features Fay described for C. spinosus, and the zoospore ultrastructures are consistent with the Group I-type Zoospore characters of Chytriomycetaceae (Chytridiales).
6 Chytridiomycota, Monoblepharidomycota, and Neocallimastigomycota
This chapter provides an overview of current classification and demonstrates how zoospore ultrastructural characters are applied within a molecular phylogenetic framework in taxonomic revision of zoosporic fungi.
Diversidade de Blastocladiomycota e Chytridiomycota do Parque Estadual da Ilha do Cardoso, Cananéia, SP, Brasil
A diverse mycota with only a few dominant taxa, most of them common to both water and soil samples, was found in the Parque Estadual da Ilha do Cardoso.

Structural Characterization of Mycobiome from the Metagenome of Lonar Lake Sediment using Next Generation Sequencing
High-throughput sequencing methods useful to enlighten the mycobiome study of extreme sitewithout culturing the fungus, detection of various industrial important species suggests the lake is vital source of important fungal metabolites.
Three new genera in Chytridiales from aquatic habitats in Argentina
Three family-level lineages are represented in the molecular phylogeny, and three new genera and species are described, emphasizing the potential for discovery of additional diversity of Chytridiales in eastern Argentina and USA.
Zoosporic true fungi in marine ecosystems: a review
Zoospores from zoosporic true fungi and other groups of microbes possibly provide important food resources for grazing and filter-feeding zooplankton and metazoans in marine ecosystems where the prevalence of disease is high or where accumulated detritus enhances biodiversity in food webs.


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.
Molecular phylogenetics of the Chytridiomycota supports the utility of ultrastructural data in chytrid systematics
A phylogeny of ribosomal DNA sequences coding for the small subunit gene of 54 chytrids, with emphasis on sampling the largest order, the Chytridiales, revealed homoplasy in several developmental and zoosporangial characters and suggested that the divergence times of these groups may be ancient.
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.
Molecular and cultural assessment of chytrid and Spizellomyces populations in grassland soils
Using MPN-PCR (a quantitative molecular technique) and traditional cultural techniques, it is found that chytridiomycetous fungi, including members of the genus Spizellomyces, are abundant in the grassland ecosystems studied.
Phylogenetic position of the genus Mesochytrium (Chytridiomycota) based on zoospore ultrastructure and sequences from the 18S and 28S rRNA gene
Ultrastructural features and a molecular phylogeny of Mesochytrium penetrans (strain X-10 CALU) based on 18S and 28S rRNA gene sequences were investigated for the first time and found that Zoospores of M. penetrans are most similar to those of Synchytrium macrosporum and Rozella allomycis, which belong to different clades.
A molecular phylogeny of the flagellated fungi (Chytridiomycota) and description of a new phylum (Blastocladiomycota).
The phylogeny suggests that Chytridiomycota is not monophyletic and there are four major lineages of chytrids: Rozella spp.
The classification of Spizellomyces, Gaertneriomyces, Triparticalcar, and Kochiomyces (Spizellomycetales, Chytridiomycetes)
A classification is given for those Chytridiomycetes with monocentric and eucarpic growth forms, endogenous sporangium development, and multipapilliated sporangia that are now known in culture and a key is given based on characters detectable by light microscopy.
Cytological variation in zoospores of Spizellomyces (Chytridiomycetes)
Differences between species are reflected by the position and shape of the nucleus, the extent of the endoplasmic reticulum which in some species circumscribes lipid globules, the presence or absence of an apparent connection by fibrillar material between the kinetosome and a nonfunctional centriole, and the morphology of the microtubule-organiz...
