Mushrooms

 This is the season for mushrooms in the Battleground yard.  I don't know the varieties.

Having read about the importance of mycorrhizal fungi, I welcome the appearance of these organisms.  Mushrooms are the fruiting bodies of vast networks of underground fungus - mycelium.  A number of works express alarm at practices that result in killing off mycorrhizae.  Fertilizers, herbicides, and tilling are the main culprits.

These fungi are considered beneficial.  They interact with plant roots to bring water and nutrients into the plants.  There is also a disease-resistance benefit.  Mycorhizae help build soil structure.  They are part of the soil ecosystem balance.
 I have added mycorrhizal inoculant to garden beds and plantings of trees and shrubs.  Given the prevalence of local mushrooms, that might not be necessary.

I think all of these originate with the local soil.  There were smaller mushrooms in one iris raised bed.  Those could either be of local origin, or via the inoculant.
