Common Gilled Mushroom

Routine blood tests for my husband this morning, which are now fortnightly rather than weekly. We were going to go out today, but the sky was overcast and there was some rain.
 
Today’s picture is of one of the several fungi that I saw in the garden this morning. The app on my phone identifies it as a Common Gilled Mushroom; if that is incorrect I am sure someone will tell me.
 
The temperature at noon today was twenty degrees Celsius.
