Summary
This study revises the fungal genus Sarocladium using DNA and phenotypic data, describing six new species. It clarifies relationships between Sarocladium and Acremonium, expanding the known spectrum of human opportunistic pathogens within Sarocladium.
Area of Science:
- Mycology
- Fungal Taxonomy
- Molecular Phylogenetics
Background:
- The fungal genus Acremonium was recently revised, leading to species transfers to Sarocladium.
- Relationships between Acremonium and Sarocladium remained unclear, necessitating further investigation.
Purpose of the Study:
- To revise species concepts within Sarocladium and related Acremonium species.
- To clarify the phylogenetic relationships between Acremonium and Sarocladium.
Main Methods:
- Multilocus phylogenetic analyses.
- Phenotypic data integration.
- Taxonomic revision of fungal species.
Main Results:
- Six new Sarocladium species are described: S. bifurcatum, S. gamsii, S. hominis, S. pseudostrictum, S. subulatum, and S. summerbellii.
- New combinations S. implicatum and S. terricola are proposed.
- Sarocladium attenuatum is confirmed as a synonym of S. oryzae; epitype and neotype designations are provided.
Conclusions:
- This study clarifies Sarocladium taxonomy and its relationship with Acremonium.
- The genus Sarocladium includes not only phytopathogens but also opportunistic human pathogens.
- The findings expand the range of clinical species identifiable as causing human infections.

01:29Fungal Group Zygomycota
2.1K
Zygomycota, previously classified as a distinct fungal group, are primarily terrestrial, saprophytic molds that play a crucial role as decomposers. Recent phylogenetic studies have revealed that these fungi are now divided into two major clades — Mucoromycota, which includes many symbiotic species, and Zoopagomycota, which primarily consists of parasitic and pathogenic fungi. These groups exhibit distinct ecological roles and reproductive strategies while sharing key structural and...

2.4K
Phylum Ascomycota, a major division within the subkingdom Dikarya, comprises a diverse range of fungal species, including both unicellular yeasts and filamentous molds such as Aspergillus and Penicillium. These fungi thrive in a variety of habitats, from aquatic ecosystems to terrestrial environments, playing crucial ecological and economic roles.Morphology and ReproductionThe defining characteristic of Ascomycetes, commonly referred to as sac fungi, is the ascus—a sac-like structure that...

64.6K
Phylogeny is concerned with the evolutionary diversification of organisms or groups of organisms. A group of organisms with a name is called a taxon (singular). Taxa (plural) can span different levels of the evolutionary hierarchy. For instance, the group containing all birds is a taxon (comprising the class Aves), and the group of all species of daisies (the genus Bellis) is a taxon. Phylogenies can likewise include just one genus (i.e., depict species relationships) or span an entire kingdom.

01:27Diversity of Protists IV
2.1K
Amoebozoa represent a diverse group of terrestrial and aquatic protists that utilize lobe-shaped pseudopodia for locomotion and feeding. This characteristic differentiates them from the Rhizaria, which possess threadlike pseudopodia. The primary classifications within Amoebozoa include gymnamoebas, entamoebas, and the plasmodial and cellular slime molds. Phylogenetic evidence indicates that Amoebozoa diverged from a lineage that ultimately gave rise to fungi and animals.Gymnamoebas and...

Rhizaria are a diverse group of unicellular protists characterized by their threadlike cytoplasmic extensions known as pseudopodia. These structures aid in both locomotion and feeding, giving Rhizaria an amoeboid appearance. Their amoeboid morphology once led to taxonomic confusion, but molecular phylogenetics has clarified their evolutionary placement and emphasized their shared use of pseudopodia despite divergent lineages.This clade comprises diverse lineages such as Chlorarachniophyta,...

Phylogenetic trees come in many forms. It matters in which sequence the organisms are arranged from the bottom to the top of the tree, but the branches can rotate at their nodes without altering the information. The lines connecting individual nodes can be straight, angled, or even curved.
