Cladochytriales—a new order in Chytridiomycota

Mycological Research, 2009
Recently, molecular and ultrastructural analyses have resulted in revised phylogenetic hypotheses in the phylum Chytridiomycota. The order Chytridiales, once considered monophyletic, has been subdivided into several new orders. However, the most recent analyses indicate that the emended Chytridiales is also polyphyletic.

A molecular phylogeny of the flagellated fungi (Chytridiomycota) and description of a new phylum (Blastocladiomycota)

Mycologia, 2006
Chytridiomycota (chytrids) is the only phylum of true Fungi that reproduces with motile spores (zoospores). Chytrids currently are classified into five orders based on habitat, zoospore characters and life cycles. In this paper we estimate the phylogeny of the chytrids with DNA sequences from the ribosomal RNA operon (18S+5.8S+28S subunits).

A new family and four new genera in Rhizophydiales (Chytridiomycota)

Mycologia, 2015
Many chytrid phylogenies contain lineages representing a lone taxon or a few organisms. One such lineage in recent molecular phylogenies of Rhizophydiales contained two marine chytrids, Rhizophydium littoreum and Rhizophydium aestuarii. To better understand the relationship between these organisms, we increased sampling such that the R.

Access to organic and insoluble sources of phosphorus varies among soil Chytridiomycota

Archives of Microbiology, 2006
The sources of minerals accessed by fungi in the Chytridiomycota (chytrid) in soil are largely unknown. The ability of ten species of soil chytrids to use various sources of phosphorus was examined in vitro. While all grew on orthophosphate, fifty per cent of isolates grew on phytic acid, and one isolate grew on DNA as the sole source of phosphorus ...

The growth response of some Chytridiomycota to temperatures commonly observed in the soil

Mycological Research, 2005
Chytridiomycota were isolated into pure culture from cool temperate and warm semi-arid soils of eastern Australia. In pure culture these fungi responded variably to the range of temperatures commonly recorded in their environment. All members of the Blastocladiales, Spizellomycetales and Chytridiales grew in culture at temperatures up to 30 degrees C ...

6 Chytridiomycota, Monoblepharidomycota, and Neocallimastigomycota

2014
Molecular phylogenetics has revolutionized our perception of relationships among zoosporic fungi. These organisms are now known to be exceedingly diverse and have adapted to a wide range of habitats from freshwater sites to harsh environments, including high alpine exposed soils.

Hypothesized evolutionary trends in zoospore ultrastructural characters in Chytridiales (Chytridiomycota)

Mycologia, 2014
Chytridiales is an order of zoosporic fungi currently comprising species representing 19 genera. Although morphologically and genetically diverse, these taxa have in common a zoospore with a suite of ultrastructural characters unique among Chytridiomycota.

Classification of marine Ascomycota, Basidiomycota, Blastocladiomycota and Chytridiomycota

Fungal Diversity, 2015
This paper lists the accepted names and classification of marine fungi, updating the scheme presented in 2009. The classification includes 1,112 species (in 472 genera): Ascomycota 805 (in 352 genera), Basidiomycota 21 species (in 17 genera), Chytridiomycota and related phyla 26 species (in 13 genera), Zygomycota three (in two genera ...

New taxa are delineated in Alphamycetaceae (Rhizophydiales, Chytridiomycota)

Nova Hedwigia, 2012
Zoospore ultrastructure and molecular phylogenetic analyses are revealing unrealized diversity among zoosporic fungi. The taxonomically challenging morphogenus Rhizophydium Schenk, with more than 220 described taxa, is now conceptually an order (Rhizophydiales Letcher) containing 10 families, 15 genera, and numerous undescribed isolates. Each family is

Some Chytridiomycota in soil recover from drying and high temperatures

Mycological Research, 2004
Rhizophlyctis rosea was found in 44% of 59 soil samples from national parks, urban reserves and gardens, and agricultural lands of eastern New South Wales, Australia. As some of the soils are periodically dry and hot, we examined possible mechanisms that enable survival in stressful environments such as agricultural lands. Air-dried thalli of R.
