Summary: In this study, three new Trichoderma species, T. nigricans, T. densissimum, and T. paradensissimum, were discovered in Chinese soils. Their phylogenetic positions were determined by analyzing the sequences of rpb2 and tef1 genes. Each new species formed a distinct clade, with T. nigricans belonging to the Atroviride Clade and T. densissimum and T. paradensissimum belonging to the Harzianum Clade. The morphology and cultural characteristics of these novel Trichoderma species were described in detail and compared with related species to elucidate their taxonomic relationships.

Summary: Fusarium infections are common in humans and economically important plants, with the Fusarium solani species complex (FSSC) being the most frequent cause in humans. This study analyzed the genotypic and phenotypic characteristics of FSSC isolates from Malaysia and identified eight different species. The taxonomic relationships were resolved phylogenetically, but a more precise MLST scheme is needed for reliable species assignment of FSSC isolates.

Summary: Stem cankers and twig dieback were observed as the most serious diseases in fig and loquat trees in Iranian fruit tree orchards. A new taxon, Stilbocrea banihashemiana sp. nov., was identified based on phylogenetic analysis and morphological observations. This novel pathogen was found to induce stem cankers, wood discoloration, and twig dieback, and may have a wide host range.

Summary: Guarana cultivation in the Brazilian Amazon is hampered by the disease caused by Fusarium decemcellulare, leading to significant yield losses. This study examined the genetic diversity and population structure of F. decemcellulare isolates from eight guarana production areas. The results revealed moderate gene diversity but high genotypic diversity. Two major populations (C1 and C2) were identified, with most of the genetic diversity found within these populations. Sexual reproduction was also observed in F. decemcellulare. Human-mediated movement of seedlings may have influenced the genetic structure of this pathogen.

Summary: The xylariaceous genus Dematophora has been separated from Rosellinia based on molecular phylogeny and morphological characters. This taxonomic change is significant as Dematophora contains important pathogens, while Rosellinia consists mainly of saprotrophic species with potential beneficial effects on host plants. New strains of rosellinoid Xylariaceae have been discovered in Iran and their mycelial cultures have been studied for secondary metabolites to establish chemotaxonomic affinities. Thirteen compounds have been isolated and identified, including three new compounds. Antimicrobial testing showed weak activity of cytochalasin E against Schizosaccharomyces pombe. Cytochalasin derivatives were also examined for cytotoxicity and their effects on actin cytoskeletal organization.

Summary: Fungal invasions can have significant consequences, but there is a lack of research on fungi in invasion science. This annotated checklist provides a comprehensive overview of alien and cryptogenic fungi and oomycetes in Austria, showing a significant increase in their numbers. Most of the introduced fungi are plant pathogens, with a small number of animal pathogens severely affecting native hosts. The dominance of pathogens highlights the importance of better understanding and managing fungal invasions.

Summary: In this study, the mitochondrial 40S ribosomal protein S10 (rps10) gene was evaluated as a locus for oomycete metabarcoding. The rps10 locus was found to have higher taxonomic resolution and less amplification of nontarget organisms compared to the internal transcribed spacer 1 (ITS1) method. The study provides a new website with a searchable rps10 reference database and protocols for oomycete metabarcoding.
