“…Class Monoblepharidomycetes, the focus of this study, is a monophyletic group of freshwater, zoosporic fungi belonging to the Chytridiomycota or core chytrid clade under most reconstructions ( James et al 2000, Forget et al 2002, Bullerwell et al 2003, James et al 2006a, Liu et al 2006, White et al 2006, Porter et al 2011, although they also have appeared as the sister of all other fungi in some studies (Tanabe et al 2005, Sekimoto et al 2011. Three genera in Monoblepharidomycetes: Monoblepharis, Monoblepharella and Gonapodya are hyphal .…”

The evolution of filamentous hyphae underlies an astounding diversity of fungal form and function. We studied the cellular structure and evolutionary origins of the filamentous form in the Monoblepharidomycetes (Chytridiomycota), an early-diverging fungal lineage that displays an exceptional range of body types, from crescent-shaped single cells to sprawling hyphae. To do so, we combined light and transmission electron microscopic analyses of hyphal cytoplasm with molecular phylogenetic reconstructions. Hyphae of Monoblepharidomycetes lack a complex aggregation of secretory vesicles at the hyphal apex (i.e. Spitzenkörper), have centrosomes as primary microtubule organizing centers and have stacked Golgi cisternae instead of tubular/fenestrated Golgi equivalents. The cytoplasmic distribution of actin in Monoblepharidomycetes is comparable to the arrangement observed previously in other filamentous fungi. To discern the origins of Monoblepharidomycetes hyphae, we inferred a phylogeny of the fungi based on 18S and 28S ribosomal DNA sequence data with maximum likelihood and Bayesian inference methods. We focused sampling on Monoblepharidomycetes to infer intergeneric relationships within the class and determined 78 new sequences. Analyses showed class Monoblepharidomycetes to be monophyletic and nested within Chytridiomycota. Hyphal Monoblepharidomycetes formed a clade sister to the genera without hyphae, Harpochytrium and Oedogoniomyces. A likelihood ancestral state reconstruction indicated that hyphae arose independently within the Monoblepharidomycetes lineage and in at least two other lineages. Cytological differences among monoblepharidalean and other fungal hyphae are consistent with these convergent origins.

“…Chytridiomycetes, Cladochytriomycetes, Lobulomycetes, Mesochytriomycetes (comprising Mesochytriales and Gromochytriales), Polychytriomycetes, Rhizophlyctidomycetes, Rhizophydiomycetes, Spizellomycetes and Synchytriomycetes (James et al 2006b;Karpov et al 2014a;Seto et al 2017;. In the Blastocladiomycota, we accommodate the family Physodermataceae in class Physodermatomycetes, which is warranted by its distinct phytopathogenic mode of nutrition, early branching position and age (505 Ma; James et al 2006b;Porter et al 2011). In Zoopagomycota, the order Zoopagales is treated at class rank (Zoopagomycetes).…”

High-level classification of the Fungi and a tool for evolutionary ecological analyses

High-throughput sequencing studies generate vast amounts of taxonomic data. Evolutionary ecological hypotheses of the recovered taxa and Species Hypotheses are difficult to test due to problems with alignments and the lack of a phylogenetic backbone. We propose an updated phylum-and class-level fungal classification accounting for monophyly and divergence time so that the main taxonomic ranks are more informative. Based on phylogenies and divergence time estimates, we adopt phylum rank to Aphelidiomycota, Basidiobolomycota, Calcarisporiellomycota, Glomeromycota, Entomophthoromycota, Entorrhizomycota, Kickxellomycota, Monoblepharomycota, Mortierellomycota and Olpidiomycota. We accept nine subkingdoms to accommodate these 18 phyla. We consider the kingdom Nucleariae (phyla Nuclearida and Fonticulida) as a sister group to the Fungi. We also introduce a perl script and a newick-formatted classification backbone for assigning Species Hypotheses into a hierarchical taxonomic framework, using this or any other classification system. We provide an example of testing evolutionary ecological hypotheses based on a global soil fungal data set.

“…This order diverges from the core chytrid clade to form a sister of a clade comprising the Zygomycota, Glomeromycota, and Dikarya (James et al 2006). Based on molecular rRNA phylogeny and ultrastructural characters, the Blastocladiales was recently reclassified from the Chytridiomycota to a new phylum, the Blastocladiomycota (Porter et al 2011). Some members of this phylum are saprotrophs; other members are parasites of fungi, algae, plants, and invertebrates (Mitchell & Deacon 1986;Deacon & Saxena 1997;James et al 2006;Gleason et al 2010).…”
