Summary: This study monitored the geographic distribution of two pathogenic fungi species causing blackleg (stem canker) of crucifers in rapeseed growing areas in Hungary. Molecular PCR analysis identified 48.7% of the isolates as Plenodomus biglobosus, indicating the non-recent introduction of the pathogen into Hungary. Multi-locus analysis revealed low genetic diversity within both species, clustering all isolates to specific subclades, which has important implications for breeding and developing management strategies.

Summary: This study provides an updated hypothesis for the evolutionary history of oligotrichs and choreotrichs based on new evidence obtained by expanding sampling of molecular information across multiple gene loci. The results reveal consistency between morphological taxonomy and an updated phylogenetic system for these two subclasses of marine planktonic ciliates.

Summary: The new species of the nematode suborder Longidorus, Longidorus armeniacae n. sp., was characterized and illustrated based on morphological and molecular data. The new species was found in the rhizosphere of apricot trees in northeast Iran. The study discusses the morphological differences between the new species and other closely related species, and reconstructs the phylogenetic relationships among the selected species of the genus using LSU D2-D3 and ITS rDNA sequences.

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: The study presents FUSARIUM-ID v.3.0, a database designed for the identification of Fusarium species using sequences of multiple phylogenetically informative loci. The version includes improvements in metadata annotation, taxon representation, sequence database availability, and tutorial files for local BLAST searches. FUSARIUM-ID will be regularly updated with newly identified species and more in-depth sampling of recognized species.

Summary: Tabebuia rosea, an economically important tree in Mexico, was found to be infected by F. pseudocircinatum causing floral malformation. The study identified the causal agent, analyzed its relationship to Fusarium spp. from another tree species, and examined mycotoxin production and mating type idiomorphs of the fungus recovered from T. rosea and Swietenia macrophylla.

Summary: This study re-evaluated the classification of Diorygma species in the Western Ghats using an integrative taxonomy approach. Through morphological, chemical, and molecular phylogenetic analyses, it was determined that the species D. karnatakense and D. dandeliense should be considered synonymous, with D. karnatakense being the accepted name. Phylogenetically, D. karnatakense is closely related to D. antillarum and D. hieroglyphicum.

Summary: This study conducted a survey for the genus Trichoderma in soil samples from Aydin province, Turkiye, and identified 88 isolates, with one isolate identified as Trichoderma guizhouense. The identification was based on both macroscopic and molecular features, as well as phylogenetic analysis. This is the first report of Trichoderma guizhouense in soil in Turkiye.

Summary: Accurate species-level identification of Fusarium is essential for disease diagnosis and management. However, there are challenges in identifying Fusarium due to the large number of phylogenetically distinct species, many of which are not formally described, and the limitations of morphology-based identification. To address this, research groups are working on populating databases with informative genes that can accurately identify Fusarium species and outlining best practices for DNA sequence-based identification.

Summary: A new species, Lepiota albofloccosa, is reported from India based on morphological and phylogenetic analyses. The combination of both morphological and molecular data confirms the novelty of this species and its classification within Lepiota sect. Lepiota. The species was found in debris under Picea smithiana and shows distinctive characteristics such as a white to milky white pileus, scaly to cottony pileus surface with floccose velar remnants, fusiform to cylindrical basidiospores, and a trichoderm composed of elongated hyphae.

Summary: The study identified various Fusarium species from understory vegetation in mango orchards with mango malformation disease (MMD) in Mexico, indicating herbaceous hosts can harbor Fusarium causing MMD. This is the first report of such hosts in Mexico and the information provided will be valuable for further study on the role of weeds in the epidemiology of MMD and disease management.

Summary: Two new populations of Xiphinema persicum n. sp., belonging to the X. americanum-group, were discovered in Semnan province and described based on morphological, morphometric, and molecular data. The new species is characterized by distinct features such as longer odontostyle, four juvenile developmental stages, and posteriorly located guiding ring, distinguishing it from closely related species. Phylogenetic relationships of the endosymbiont bacterium were also analyzed using partial sequences of 16S rDNA.
