Powdery white fungus

Powdery white fungus

Observation - Powdery white fungus - UK and Ireland. Description: This, what I think must be some sort of fungus, appeared overnight on our lawn after a light frost.

This, what I think must be some sort of fungus, appeared overnight on our lawn after a light frost. It has been suggested that it is ‘dog sick fungus’ but it isn’t at all slimy, it is pure white. It looked like snow - it is that powdery, but has lasted for two days, unchanging and in bright sunlight.
