Communities of saprotrophic (“rotten material” + “plant”) fungal hyphae (web) that break down wood chips and above ground plant litter tend to fruit mushrooms to spread their spores by air, mold uses explosive sacs to spread their spores into the air, whereas root-associated endo (internal to the root) or ecto (external) mycorrhizae (“fungus” + “root”) form symbiotic relationships with living plants and reproduce from spores in sacs on the hyphae (web) at the roots. Without plants to host them, mycorrhizae tend to die off. The different types are also often vertically separated in soils. So you want both types, and collecting above ground litter and below ground feeder roots can help spread the latter. Succession in forests has been shown to correlate with the interconnectedness of plants and so collecting fungal species that can interconnect plants at their roots or decompose material aboveground to feed them will aid succession. When a tree falls and is left to decompose it creates a food pathway for fungal hyphae to create super highways connecting plants. We can replicate this by leaving intact trunks or branches in contact with soil between plants. One of the highest minerals in trees is potassium, and potassium increases the colonisation of plant roots by mycorrhizae.
The white strings aka hyphae (webs) often seen in wood chips and compost can also be formed by bacteria such as Actinomycetes.
There have also been studies showing that most products claiming to contant inoculants that have mycorrhizal spores, don’t.
The brown-rot fungal wood decay resulted in higher concentrations of soil C and N and a greater increase in microbial necromass (i.e., 1.3- to 1.7-fold greater) than the white-rot fungal wood decay. The white-rot sets were accompanied by significant differences in the proportions of the bacterial residue index (muramic acid%) with soil depth; however, the brown-rot-associated soils showed complementary shifts, primarily in fungal necromass, across horizontal distances. Soil C and N concentrations were significantly correlated with fungal rather than bacterial necromass in the brown-rot systems. Our findings confirmed that the brown-rot fungi-dominated degradation of lignocellulosic residues resulted in a greater SOM buildup than the white-rot fungi-dominated degradation.
