These environmental cues induce macrofungi (mushrooms and similar large species) to transition from repeating cycles of asexual reproduction, (through vegetative hyphae and…  More 

Bottomland Hardwood Restoration – What Happens Belowground?

However,…  More 

Into the Rhizosphere: Soil Fungi and Carbon Dynamics

Underneath the Earth’s surface, water, nutrients, and chemical signals are shuttled through a sprawling network between tree roots and soil fungi. “Many forest trees depend on their associated soil fungi for nutrients, as the fungi are better at absorbing nitrogen, phosphorous, and other nutrients,” says U.S. Forest Service ecologist Melanie Taylor. “The trees return the…  More
