Summary: A new plant species, Oreocharis xieyongii, is described from Hunan Province, central China. Its distinctive features include a purple zygomorphic corolla with longer adaxial lobes and exserted stamens, which set it apart from other Oreocharis species. Phylogenetic analysis reveals its placement within the Oreocharis genus. Comparative analysis with similar species highlights the unique traits of O. xieyongii. The study provides both morphological and molecular evidence supporting the recognition of O. xieyongii as a new taxon.

Summary: Through morphological and molecular phylogenetic studies, it has been discovered that European and American names of wild mushrooms were often mistakenly applied to Asian lookalikes in the past. Consequently, taxonomical research on wild mushrooms has been intensified in Asian countries, including India, in recent years to reveal the true mushroom diversity. In this study, four new species and two species new to India were identified and established based on morphology and molecular phylogeny.

Summary: During field investigation in northeastern China, six new species within Gerhardtia and Ossicaulis genera were discovered. Through morphological and molecular methods, two new species were confirmed in each genus. This study provides a theoretical basis for these two genera and suggests that the biodiversity resources of northeastern China might be underestimated.

Summary: Water-soluble polysaccharides (SVPs) were extracted from the medicinal fungus Sanghuangporus vaninii and four polysaccharide sub-fractions were isolated, with SVP-1 showing significant inhibition of non-small cell lung cancer cells and potential for therapy. The findings suggest that SVP-1, a natural acidic polysaccharide, has antitumor activity and induces cell apoptosis in lung cancer cells.

Summary: Through morphological, ecological, and distributional analysis, it was discovered that Chara denudata from South Africa and C. dissoluta from Central Europe, originally believed to be the same species, are in fact distinct species. The presence of different traits and their distinct biology, habitat preference, and distribution confirms that the 'unfinished' morphogenesis in charophytes can hide different speciation pathways.

Summary: Flammulina rossica fermentation extract (FREP) was obtained by ethanol precipitation and had a molecular weight of 28.52 kDa. It mainly contained active ingredients such as polysaccharides, proteins, reducing sugars, and amino acids. The immunoregulatory activities of FREP were investigated in healthy and immunosuppressive mice, and the results showed that FREP could increase lymphocyte counts, cytokine levels, and promote cell proliferation. Finally, FREP could restore blood cell counts and improve immune function in immunosuppressive mice, indicating its potential as an immunomodulatory agent.

Summary: A new strain of oogamous biflagellate green alga was discovered and classified as part of the RL clade within Oogamochlamydinia. It shares similarities with members of the genus Oogamochlamys but differs in certain cell morphology and structure features. Despite the doubts about its relation to Oogamochlamys based on phylogenetic analysis, the strain from Iturup Island is described as a new species, Oogamochlamys kurilensis.

Summary: Luticola tenera is a widespread diatom species found in various habitats, with distinct morphological characteristics and reproductive modes. Phylogenetic analyses show its affinity to the genus Luticola. The new strain shares morphological features with other Luticola species but differs in valve width and the shape of external proximal raphe ends. It reproduces via isogamy and cis-anisogamy. These phenotypic traits led to the description of the new isolate as Luticola tenera sp. nov.
