The use of non-pollen palynomorphs (NPP), particularly fossil fungi and algae, as palaeobiological proxies for Late Cretaceous palaeoenvironmental palaeoclimatic reconstructions warm-to-hot greenhouse conditions, can enhance our understanding climate change impacts on modern Patagonian environments. This study aimed to reconstruct the Maastrichtian palaeoenvironment palaeoclimate in Cañadón Asfalto Basin (CAB, Chubut Province) by testing these NPPs using Nearest Living Relative method (NLR).

The exploration of endophytic fungi associated with seaweeds has garnered significant interest due to their crucial ecological functions and potential as sources valuable bioactive compounds. In this study, we isolated identified from the brown seaweed Dictyopteris pacifica, collected intertidal zone Yeongdoek, Gyeongsangbuk-do in Korea. Through morphological examination molecular phylogenetic analysis using multiple markers, including ITS, LSU, SSU, TEF1, TUB2, RPB2 sequences, three fungal species not previously recorded Korea: Emericellopsis fuci, Neoarthrinium lithocarpicola, Periconia chimonanthi. Detailed descriptions characteristics analyses are provided. This study represents first report these D. pacifica Korea, thereby enhancing understanding diversity seaweed-associated region.

The fungal genus Nigrospora is known to be a plant pathogen, endophyte, and saprobe, it usually isolated from various substrates like soil air. During the surveys of fungi in Hebei Province China, two isolates were obtained. A multi-locus phylogeny combined loci 5.8S nuclear ribosomal gene with flanking transcribed spacers (ITS), part translation elongation factor 1-alpha (tef1), beta-tubulin (tub2) loci, conjunction morphological characters used identify newly collected isolates. humicola sp.

The genus Preussia is widely distributed and includes species with ecological biotechnological importance. In this study, morphological phylogenetic analyses of the ITS LSU rDNA sequences revealed two novel species, P. jejuensis sp. nov. koreensis nov., as well one previously unrecorded in Korea, isomera, from horse dung collected Seopjikoji, Jeju Island, Republic Korea. unique producing conidia conidiomata instead teleomorphic structures, a feature not observed any other known genus. morphologically distinguished by absence neck, smaller ascocarp diameter, asci, larger ascospores. analysis, was closely related to isomera S. minimoides, while arizonica, persica, minima. However, were clearly their species. This study expands understanding biodiversity coprophilous fungi its distribution region where breeding has been practiced for centuries, emphasizing importance fungal habitat.

145 fungal isolates were obtained from three sampling sites situated within the Nam River basin, located in southern region of South Korea. Through ITS sequence analysis, identified to comprise 55 species ascomycetes and 11 basidiomycetes. The exclusively belong phylum Pezizomycotina, comprising 33 Dothideomycetes, 6 Eurotiomycetes, 16 Sordariomycetes. Regarding their plant pathogenicity, an investigation into fungi's ability penetrate solid media revealed Nigrospora chinensis as displaying highest growth, followed by Pseudopestalotiopsis theae, various Curvularia species, Diaporthe Alternaria alternata. Further research associating this penetration with pathogenicity is deemed necessary. Among 10 exhibiting abilities, examination capability degrade biological polymers that two strains D. phaseolorum displayed exceptional polymer degradation. These exhibited remarkable abilities decomposing malachite green crystal violet, both recalcitrant dyes.
