We investigated the phylogenetic relationships of the Chytridiomycota and the chytridiomycetous gut fungi with a cladistic analysis of 42 morphological, ultrastructural, and mitotic characters for 38 taxa using both maximum parsimony and distance algorithms. Our analyses show that there are three major clades within the Chytridiomycota: the gut fungi, the Blastocladiales, and the Spizellomycetales–Chytridiales–Monoblepharidales. Consequently, we elevated the gut fungi to the order… Expand

Molecular phylogenetics of the Chytridiomycota supports the utility of ultrastructural data in chytrid systematics
TLDR
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. Expand
Phylogeny of anaerobic fungi (phylum Neocallimastigomycota), with contributions from yak in China
TLDR
A comparative phylogenetic revision of Neocallimastigomycota isolates known from culture and sequence data shows that ITS, specifically ITS1 alone, is not a good marker to resolve the generic affinities of the studied fungi. Expand
A higher-level phylogenetic classification of the Fungi.
A comprehensive phylogenetic classification of the kingdom Fungi is proposed, with reference to recent molecular phylogenetic analyses, and with input from diverse members of the fungal taxonomicExpand
THALASSOCHYTRIUM GRACILARIOPSIDIS (CHYTRIDIOMYCOTA), GEN. ET SP. NOV., ENDOSYMBIOTIC IN GRACILARIOPSIS SP. (RHODOPHYCEAE)
Thalassochytrium gracilariopsidis gen. et sp. nov. is an endosymbiotic, polycentric, zoosporic fungus that infected cultures of the red alga Gracilariopsis sp. Based on the posteriorly uniflagellateExpand
Loss of the flagellum happened only once in the fungal lineage: phylogenetic structure of Kingdom Fungi inferred from RNA polymerase II subunit genes
TLDR
The results suggest that loss of the flagellum happened only once during early stages of fungal evolution; consequently, the majority of fungi, unlike plants and animals, are nonflagellated. Expand
Anaerobic fungi (phylum Neocallimastigomycota): advances in understanding their taxonomy, life cycle, ecology, role and biotechnological potential.
TLDR
The move towards understanding of anaerobic fungi using -omics based (genomic, transcriptomic and proteomic) approaches is starting to yield valuable insights into the unique cellular processes, evolutionary history, metabolic capabilities and adaptations that exist within the Neocallimastigomycota. Expand
Caecomyces sympodialis sp. nov., a new rumen fungus isolated from Bos indicus.
TLDR
A new anaerobic rumen fungus was isolated from the rumen fluid of a yellow cow, appearing to be a previously undescribed species of the genus Caecomyces, it possessing uniflagellate zoospores, a spherical holdfast, tubular sporangiophores and bulbous rhizoids. Expand
Caecomyces sympodialis sp. nov., a new rumen fungus isolated from Bos indicus
A new anaerobic rumen fungus was isolated from the rumen fluid of a yellow cow (Bos indicus). This fungus appears to be a previously undescribed species of the genus Caecomyces, it possessingExpand
Identification and characterization of anaerobic gut fungi using molecular methodologies based on ribosomal ITS1 and 18S rRNA.
TLDR
DNA slot-blot analysis using ribosomal sequences is able to differentiate between gut fungal genera and thus has considerable potential for use in ecological studies of these organisms. Expand
Cyllamyces aberensis gen. nov, sp. nov.: a new anaerobic gut fungus with branched sporangiophores isolated from cattle
TLDR
Limited polycentric thallus development (including branched sporangiophores), the possession of a single bulbous holdfast and the absence of rhizoids were stable features of this fungus that distinguished it from the other five genera of gut fungi. Expand

The phylogenetic relationships of the anaerobic chytridiomycetous gut fungi (Neocallimasticaceae) and the Chytridiomycota. I. Cladistic analysis of rRNA sequences
TLDR
The results suggest that the Chytridiomycota are clustered with other fungi with 98, 76, and 30% confidences in the Fitch–Margoliash, neighbour-joining, and maximum parsimony algorithms, and none of these three algorithms place any of 17 protists from 12 phyla with the fungi, including the chytrids.

Molecular evolution of the fungi: relationship of the Basidiomycetes, Ascomycetes, and Chytridiomycetes.
TLDR
DNA sequences of nuclear small-subunit ribosomal RNA genes were used to determine phylogenetic relationships among three major classes of organisms considered to be fungi and to assess the taxonomic position of Neocallimastix, an economically important anaerobic rumen microorganism whose classification is controversial.

TLDR
It is proposed that zoospores of the advanced members of the class Chytridiomycetes have reached limits for further zoospore development because of size; however, the Zoospore is no longer essential for them because they have developed a filamentous habit of growth. Expand
CAULOCHYTRIUM PROTOSTELIOIDES SP. NOV., A NEW CHYTRID WITH AERIAL SPORANGIA
TLDR
The newly described species, C. protostelioides, which was discovered first in the British West Indies and then in North Carolina, is an obligate parasite of the dematiaceous fungus Cladosporium, and the family Caulochytriaceae and genus Caul Cochytrium are emended. Expand
Ultrastructural description of a new chytrid genus of caecum anaerobe, Caecomyces equi gen. nov., sp. nov., assigned to the Neocallimasticaceae.
TLDR
On the basis of zoospore ultrastructure, the new genus Caecomyces equi is assign to the Neocallimasticaceae of the order Spizellomycetales and Organisms previously described as Sphaeromonas communis and Piromyces communis are renamed and assigned to the same family. Expand

Comparative ultrastructure and biochemistry of chytridiomycetous fungi and the future of the Harpochytriales
TLDR
A system of cisternae that are associated with microbodies appears to connect the lipid globules in the anterior region with the rumposomal complex in the posterior region of these zoospores, which is very similar to that of chytridiomycetous fungi. Expand

TLDR
The rumen fungi have many characteristics in common with the Spizellomycetaceae but have been given their own family, the Neocallimasticaceae, which is a monophyletic group with extreme diversity in thallus morphology, reproduction and zoospore cytology. Expand
