Summary: A new method was developed to extract mycelial fibers from mushrooms without destroying their structure. The fruiting bodies were treated with NaOH and H2O2, and decolorized using sunlight irradiation. The resulting mycelium pulp is a completely new material that retains its mycelial structure, demonstrating excellent deformability and a wide range of material applicability.

Summary: This study evaluates the accumulation ability of 59 oyster mushroom strains in terms of selected metals in the cap and stipe. The research reveals the differential accumulation of metals and confirms the dependence of metal uptake on substrate fortification. The findings can contribute to the selection of production strains with hyperaccumulation properties and have implications for food safety.

Summary: Nine pyrrole alkaloid derivatives, including four new ones, were isolated from Lentinula edodes for the first time. Their chemical structures were determined using various spectroscopic and crystallographic techniques. Compound 1, a previously unreported bicylo-pyrrole aldehyde homologue, was found to be a major component in the mushroom with cytotoxic activity against SMMC-772 cells. Compounds 1 and 2 displayed weak immunosuppressive activities, while compound 3 showed inhibition activity on the proliferation of HaCaT cell line and weak antioxidant activity.

Summary: The study aimed to increase the folate content in Flammulina velutipes mushrooms, finding that treating the substrate with synthetic folic acid significantly increased folate levels in the fruiting bodies. Different patterns of changes were observed in the levels of various folate compounds, with the most inconsistency seen in tetrahydrofolate content.

Summary: Edible mushroom sexual spores have gained increasing interest due to their bioactive components and functions. This review summarizes the bioactive nutrients of these spores, describes the mechanism of spore discharge, and analyzes the relationship between postharvest spore discharge and mushroom quality. Spores contain various bioactive nutrients that are beneficial to human health. Mature mushrooms can actively discharge spores, which is influenced by light, relative humidity, and temperature. Storage leads to vigorous physiological metabolism of spore-bearing gill tissue, promoting postharvest spore release and altering the nutritional value of fruiting bodies. The flavor of the fruiting bodies also changes significantly during spore discharge. Edible mushroom sexual spores have the potential to be used as new raw materials for functional food and medical resources. Research on the effect of spore discharge on mushroom quality and the development of spore discharge regulation technology may be a new trend in quality control and promotion of the edible mushroom industry.

Summary: This study provides the genome of Hericium rajendrae for the first time and explores the genomic differences, evolutionary characteristics, and gene family variation between this species and other Hericium species. Candidate genes associated with the mating system, carbohydrate-active enzymes, and secondary metabolite biosynthesis were identified based on genomic bioinformation. Metabolite profiling and comparative gene clusters analysis further supported the biosynthetic pathway of erinacines in H. rajendrae. These findings enrich the genomic content of the genus Hericium and have significant implications for understanding H. rajendrae and advancing its application in pharmaceutical and functional food production.

Summary: Coriolus versicolor, an edible medicinal mushroom in China, contains two polysaccharides CVPn and CVPa, which have been shown to possess immunomodulatory abilities on RAW 264.7 macrophages. CVPa, with higher molecular weight and fewer branches, induces significant production of NO, iNOS, and TNF-alpha mRNA expression levels in cells, suggesting enhanced immunomodulatory potential compared to CVPn.

Summary: This study evaluated the nutritional and medicinal value of four cultures of O. gracilis by analyzing their metabolite composition. The results showed significant differences in metabolite composition among the cultures, with each culture accumulating some active metabolites. The fruiting bodies had the most abundant metabolites compared with other cultures. Additionally, seven metabolic pathways closely related to fruiting body formation were identified.

Summary: Qualitative analysis of hexane extracts from different trama layers of dried fruiting bodies of Ganoderma applanatum collected in North-East Armenia revealed the presence of three sterols with varying content and ratio in each layer. The weight loss of the trama samples during drying was observed, and the complete extraction of sterols took six days.

Summary: The study revealed enriched metabolic pathways in abnormal L. edodes fruiting bodies and identified certain protein families related to malformation. Heat shock proteins, G proteins, and β-1,3-glucanase genes showed different expression patterns in L. edodes fruiting body development, and cellulose-degrading enzymes were highly expressed in abnormal fruiting bodies.
