Arbuscular mycorrhizal fungi (AMF) are symbiotic organisms essential for nutrient exchange with ~70% of plant species. A recent study utilized data from 322 studies and machine-learning models to reveal global topsoils host ~1.1 × 10¹⁷ kilometers of AMF hyphae, weighing ~300 megatons. This biomass surpasses human biomass by 4- to 6-fold, highlighting the significant ecological role of AMF networks.

This review highlights Ganoderma formosanum’s potential in biotechnology as a fermentation-enhanced alternative within the Ganoderma genus. Notably, optimized fermentation yields high mycelial biomass and β-glucan-rich exopolysaccharides, with significant health benefits, including Th1-biased immunomodulation and anti-melanogenic activity. Despite lacking human trials, its scalable bioactivities position it as a promising candidate for functional foods and cosmeceuticals.

This study examines how nitrogen (N) enrichment and the fungal endophyte Epichloë amarillans affect plant traits in a nutrient-poor sand dune. Findings reveal that while N enrichment alters plant size and leaf area, increasing productivity, the presence of Epichloë mitigates impacts on root traits, suggesting significant community-level effects beyond its host, Ammophila breviligulata.

This study utilizes integrative metabolomic and transcriptomic approaches to investigate two medicinal fungi, Ganoderma leucocontextum and G. lucidum. Findings highlight G. leucocontextum's higher ganoleucoin levels versus G. lucidum's ganoderic acid. Elevated CYP450 gene expression in G. lucidum aligns with active triterpenoid pathways, illuminating species-specific metabolite regulation.

The diversity of soil fungi, crucial microbial entities providing essential ecological services, remains underexplored in African soils. This study, the largest of its kind, employs eDNA metabarcoding from 467 samples across 32 countries, revealing hotspots in savannas and tropical forests. Precipitation and latitude significantly influence fungal alpha diversity, providing a crucial reference for future conservation and research efforts.

This study examines how loess, calcareous, and laterite soils in Guangxi, China, influence tomato rhizosphere microbial communities. Findings reveal distinct microbial assemblages, with laterite soil enriched in beneficial fungi like Curvularia and bacteria including Bacillus, offering superior conditions for tomato growth. These insights support targeted soil management to enhance productivity.

This study explores the taxonomy of rust fungi (Pucciniales, Basidiomycota) in Brazil's Cerrado. Researchers identified novel species and genera, highlighting that only 13% of potential rust fungi are documented here. These findings underscore the urgency of integrating fungal systematics with conservation efforts in this highly threatened biome.

This study investigates Phylloporia fungi, revealing four new species in Arabuko Sokoke National Park, Kenya, through morphological, ecological, and phylogenetic analyses. Notably, Phylloporia pulchella and P. thecacoris lack close phylogenetic relatives, highlighting unique evolutionary paths. A key to the species in tropical Africa is included for further study.

This study delves into the diversity of Peziza echinospora, a cup-fungi species reliant on burnt ground, confirming its presence in Australia through multilocus phylogenetic analyses. Remarkably, it introduces two new species: P. austroechinospora, with larger spiny ascospores, and P. meridionalis, featuring smooth ascospores, which intriguingly functions as an orchid root endophyte.

This study investigates the fungal communities in eastern larch beetle (Dendroctonus simplex) galleries amid a prolonged outbreak in Minnesota's Larix laricina forests. Researchers identified 45 fungal species, four being novel Ophiostomatales, and propose taxonomic revisions for Leptographium simplex. Dominant among the isolates was Ascomycota, particularly the Ophiostomatales.

In dry tropical forests of Mexico, two novel Tulostoma species, T. parvirufula and T. chamelensis, have been identified. Morphological analysis and DNA sequencing reveal distinctive traits, such as spore sac size and basidiospore ornamentation. Phylogenetic studies place them near clade 11, highlighting their unique evolutionary lineage and enriching our understanding of Tulostoma diversity.

This study examines shifts in plant-fungal symbiont interactions under prolonged warming in subalpine grasslands. Over 29 years, experimental warming led to a 150% increase in woody vegetation, reduced reliance on mycorrhizal fungi by 17-20%, and a 10% rise in soil saprotrophic fungi. These shifts suggest a move toward more conservative ecosystems, resembling desert shrublands.
