Fungal Species: Suillus

Metabarcoding Unveils Seasonal Soil Microbiota Shifts and Their Influence on Boletus edulis and Boletus reticulatus Mycelium in Quercus robur Stands

mycolabadmin

This research studied how soil bacteria and fungi change across fall months in oak forests in Spain and how these changes relate to the growth of valuable edible mushrooms (Boletus species). Scientists used DNA analysis to identify thousands of different microorganisms in the soil. They found that September had the most diverse microbial communities, October showed a decline, and November saw partial recovery. Importantly, Boletus mycelium showed different patterns of growth depending on the month and was associated with specific beneficial bacteria and fungi.

A trait spectrum linking nitrogen acquisition and carbon use of ectomycorrhizal fungi

mycolabadmin

Different types of ectomycorrhizal fungi have evolved distinct strategies for acquiring nutrients from soil and transferring them to trees. The study proposes that these fungi can be arranged on a spectrum from ‘absorbers’ that quickly grab available nutrients in fertile forests to ‘miners’ that slowly exploit tough organic matter in poor forests. This framework explains why the same fungus behaves differently depending on soil fertility and unifies seemingly contradictory observations about fungal responses to nutrient additions.

A trait spectrum linking nitrogen acquisition and carbon use of ectomycorrhizal fungi

mycolabadmin

Forest mushroom fungi form partnerships with tree roots to help them get nutrients from soil. This research proposes that these fungi fall into two main types along a spectrum: ‘absorbers’ that quickly build large fungal networks to capture easily available nitrogen, and ‘miners’ that slowly grow elaborate cord systems to break down difficult organic matter and extract nitrogen. The study uses math models to show how different fungal strategies affect both how much carbon the trees provide and how much nitrogen returns to the trees.

Mycelial communities associated with Ostrya carpinifolia, Quercus pubescens and Pinus nigra in a patchy Sub-Mediterranean Karst woodland

mycolabadmin

This research studied how fungi living in soil connect to different tree roots in a rocky Mediterranean forest in Slovenia. Scientists found that different tree species have their own preferred fungal partners, though some fungi work with multiple trees. The fungi with longer connections through soil were more common under pine trees, while fungi with shorter reach were more common under oak and hornbeam trees.

Mushroom Bioactive Molecules as Anticancerous Agents: An Overview

mycolabadmin

Mushrooms contain natural compounds that show promise in fighting cancer by triggering cancer cell death and boosting immune function. Different mushroom species like oyster, shiitake, and button mushrooms contain substances such as beta-glucans and other polysaccharides that have demonstrated anticancer properties in laboratory and animal studies. While these mushroom compounds work through multiple mechanisms including preventing new blood vessel formation to tumors and stopping cancer cell division, more human clinical trials are needed to confirm their effectiveness as cancer treatments.
