Summary: | Cladochytriales
comprises a taxonomic order and lineage of chytrid fungi that are primarily saprobes of organic matter in aquatic and terrestrial ecosystems. The order contains species from 12 genera, though molecular confirmations of almost all type species are lacking, and many genera are considered polyphyletic. We conducted phylogenetic analyses of ribosomal RNA genes and developmental morphology of
Cladochytriales
isolates from the Collection of Zoosporic Eufungi at the University of Michigan and noted some strains that were distinct from described genera. In our phylogenetic analysis,
Endochytriaceae
represented by only one strain of
Endochytrium ramosum
was sister to
Septochytriaceae
while the
incertae sedis
lineage formed by the new species
Thomasia carolinae
was sister to
Nowakowskiellaceae
. Additionally, the phylogenetic relatedness of the other two new species,
Dogmamyces elongatus
and
Allochytrium aureum
, was also highly supported. A thorough revision of the order is needed because some genera, such as
Catenochytridium
and
Nephrochytrium
, remain polyphyletic or paraphyletic. In addition to indicating these problems, our updated phylogeny supports the description of two new genera and three new species and thereby begins to bring the knowledge of the
Cladochytriales
up to date. |
