TL;DR: Three new primers are described - fITS7, gITS7 and fITS9 - which may be used to amplify the fungal ITS2 region by targeting sites in the 5.8S encoding gene and yielded more diverse amplicon communities than the ITS1f primer.

TL;DR: Observations show that the degrading and nutrient-mobilizing components of the fungal community are spatially separated, which has important implications for biogeochemical studies of boreal forest ecosystems.

TL;DR: Fungal nutritional mode diversification suggests that the boreal forest biome originated via genetic coevolution of above- and below-ground biota through convergent evolution and divergence among fungal decomposers.

TL;DR: Cultivation and cloning allow phylogenetic placement of a prominent fungal lineage, Archaeorhizomycetes, phylogenetically placed within subphylum Taphrinomycotina in the Ascomycota, which comprises hundreds of cryptically reproducing filamentous species that do not form recognizable mycorrhizal structures and have saprotrophic potential, yet are omnipresent in roots and rhizosphere soil and show ecosystem and host root habitat specificity.

TL;DR: The role of the fungus Chalara fraxinea in decline of Fraxinus excelsior, which is observed on a large scale in central and northern Europe with high incidence of tree mortality, is clarified and fungal communities inhabiting tissues with symptoms are studied.
