Mould in soil?

Hi,
I found some grey / white powdery patch in soil underneath some bushes.
Does anyone know if this is some type of fungus? I'm concerned it might be dangerous or may destroy the bushes.

 

Hi @Franc It's a fungal mycelium of some kind, probably made visible by the dryness of the soil under the bushes. However, it's almost certainly nothing to worry about as there are (literally) millions of species, most of them harmless or beneficial (and currently unidentified!)
You can fork it over if you are planting (e.g. bulbs) in that spot.

 

I sometimes find this, never been a problem.

 

Thanks for the responses.
This is a patch over a foot in diameter. It seems quite big. I had posted a picture but it doesn't seem to be showing up here.
I had seen small white (<5mm) balls or nodules in another part of the garden. Would this be the same type of growth?
