Kickxellomycotina is a recently described subphylum encompassing four zygomycete orders (Asellariales, Dimargaritales, Harpellales, Kickxellales). These fungi are united by the formation of disciform septal pores containing lenticular plugs. Morphological diversification and life history evolution has made the relationships within and among the four orders difficult to resolve on those grounds alone. Here we infer the phylogeny of the Kickxellomycotina based on an eight-gene supermatrix… 

Evolutionary relationships among Massospora spp. (Entomophthorales), obligate pathogens of cicadas

The results of the morphological study presented here indicate that spore measurements are not phylogenetically or diagnostically informative and the emerging phylogenetic framework can provide a foundation for exploring co-evolutionary relationships with cicada hosts as well as the evolution of behavior-altering compounds.

Challenges and Future Perspectives in the Systematics of Kickxellomycotina, Mortierellomycotina, Mucoromycotina , and Zoopagomycotina

Evidence suggests that genome sequencing from a wide array of taxa in these four subphyla combined with innovative environmental sampling approaches is likely to revolutionize the authors' understanding of these fungi and also the fungal tree of life.

A new genus Unguispora in Kickxellales shows an intermediate lifestyle between saprobic and gut-inhabiting fungi

A new term, “amphibious fungi,” is introduced to describe fungi that have two life stages, one outside and the other inside the host gut, like U. rhaphidophoridarum.

A phylum-level phylogenetic classification of zygomycete fungi based on genome-scale data

It is demonstrated that zygomycetes comprise two major clades that form a paraphyletic grade, and the phyla Mucoromycota and ZoopagomyCota are circumscribed.

A taxonomic revision of the genus Conidiobolus (Ancylistaceae, Entomophthorales): four clades including three new genera

The well-known Conidiobolus is revised and three new genera Capillidium, Microconidiabolus and Neoconidioblus are proposed along with one new record and 22 new combinations.

New insights from molecular phylogenetics of amoebophagous fungi (Zoopagomycota, Zoopagales)

The first molecular characterization of the genus Stylopage is provided, which is closely related to the genus Acaulopage, and taxonomy and phylogeny of amoebophagous fungi and their ecological importance are reviewed based on new sequence data, which includes environmental clonal sequences.

Preliminary phylogeny of Coemansia (Kickxellales), with descriptions of four new species from Taiwan

Phylogenetic analysis based on a combined data set of D1–D2 domains of nuc 28S ribosomal RNA (rDNA) and partial nuc 18S rDNA identifies several independent evolutionary lineages within Coemansia and suggests that Spirodactylon aureum and Kickxella alabastrina may be nested within the genus CoemANSia.

New species and emendations of Orphella: taxonomic and phylogenetic reassessment of the genus to establish the Orphellales, for stonefly gut fungi with a twist

A molecular phylogeny based on nuc rDNA 18S and 28S is presented, which supports Orphella as a lineage distinct from Harpellales, and a new order, Orphellales, is established for it.

Genome-Wide Survey of Gut Fungi (Harpellales) Reveals the First Horizontally Transferred Ubiquitin Gene from a Mosquito Host

This is the first record of a horizontally transferred ubiquitin gene from disease-bearing insects to the gut-dwelling fungal endobiont and should invite further exploration in an evolutionary context.



Phylogeny of the Zygomycota based on nuclear ribosomal sequence data.

A molecular-based phylogeny including recognized representatives of the Zygomycetes and TrichomycETes with a combined dataset for nuclear rRNA 18S (SSU), 5.8S and 28S (LSU) genes is presented.

Evolutionary implications of a rRNA-based phylogeny of Harpellales.

Molecular phylogeny of parasitic zygomycota (Dimargaritales, zoopagales) based on nuclear small subunit ribosomal DNA sequences.

The 18S rDNA phylogeny is mostly consistent with traditional phenotypic-based classification schemes of the Fungi, as reflected by low bootstrap and decay index support for virtually all internal nodes uniting ordinal and superordinal taxa.


Representatives from the three trichomycete orders: the Amoebidiales, Eccrinales, and Harpellales were found in various arthropods from Western North America. Amoebidium parasilicum Cienk. was noted

Examining new phylogenetic markers to uncover the evolutionary history of early-diverging fungi: comparing MCM7, TSR1 and rRNA genes for single- and multi-gene analyses of the Kickxellomycotina

Phylogenetic inference suggests that Barbatospora, Orphella, Ramicandelaber and Spiromyces may represent unique lineages among other groups of early-diverging fungi.

Molecular evolution of the small subunit ribosomal DNA in woodlice (Crustacea, Isopoda, Oniscidea) and implications for Oniscidean phylogeny.

The phylogenetic analyses of the ssu rDNA support a repeated independent evolution of the three different types of pleopodal lungs in the Crinochaeta.

Phylogenetic relationships among ascomycetes: evidence from an RNA polymerse II subunit.

Findings show that a slowly evolving protein-coding gene such as RPB2 is useful for diagnosing phylogenetic relationships among fungi, and suggests that fruiting body formation and forcible discharge of ascospores were characters gained early in the evolution of the Ascomycota.

Reconstructing the early evolution of Fungi using a six-gene phylogeny

It is indicated that there may have been at least four independent losses of the flagellum in the kingdom Fungi, and the enigmatic microsporidia seem to be derived from an endoparasitic chytrid ancestor similar to Rozella allomycis, on the earliest diverging branch of the fungal phylogenetic tree.

Loss of the flagellum happened only once in the fungal lineage: phylogenetic structure of Kingdom Fungi inferred from RNA polymerase II subunit genes

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.
