Article Synopsis
- The study investigates the phylogenetic relationships of two morphologically similar fungal genera within the Sordariomycetes, confirming they are congeneric and proposing new combinations for their classification.
- New species were identified through molecular data, particularly using specific gene markers, as traditional morphology was insufficient for distinguishing them.
- The research highlights the importance of the ascogenous system for genus identification and discusses the global diversity and biogeography of the genera, including the publication of whole-genome analyses to improve taxonomic standards.
Article Synopsis
- The study focuses on the morphological and genetic variability of certain fungi species, some of which are identified as chloridium-like asexual morphs, requiring reevaluation in taxonomy and phylogeny.
- By analyzing 71 strains and conducting phylogenetic reconstruction using four DNA loci, the researchers identified two distinct orders and nine separate genera within a complex group of fungi.
- The research introduces four new species and eight new combinations, offering a clearer understanding of these fungi's classification and relationships, which will aid future identification efforts.
Article Synopsis
- The text discusses a little-understood group of soil- and wood-inhabiting fungi that reproduce through a rare process involving multiple locations and were previously classified into three sections, but recent studies show this classification is outdated.
- A new classification proposal is introduced, recognizing these fungi as a polythetic genus with 37 species divided into eight sections, alongside the reclassification of some species into a new genus.
- Additionally, the study highlights the ecological role of these fungi, noting their common presence in soil, association with forest habitats, and sensitivity to climate, supported by data from the GlobalFungi database.
The genus is a phialidic, dematiaceous hyphomycete known for its intriguing morphology and turbulent taxonomic history. This polyphasic study represents a new, comprehensive view on the taxonomy, systematics, and biogeography of and its relatives. Phylogenetic analyses of three nuclear loci confirmed that is polyphyletic.

Recent studies on HCC have demonstrated dramatic alterations in expression of several cytochrome P450 (CYP) family members that play a crucial role in biotransformation of many drugs and other xenobiotics; however, the mechanisms responsible for their deregulation remain unclear.
Methods: We investigated a potential involvement of miRNAs in downregulation of expression of CYPs observed in HCC tumors.
