Mushrooms in my garden, help...

Help me celebrate!
Thanks, fungal activity, for letting me know I'm at least doing something right.
This is the second year for this garden with used to be a lawn.
The plants that are doing the best are the surprise volunteers from last year.

These are pretty small,and so they are harder to identify. Many mycologists use the non-scientific term LBM for little brown mushroom, which means it is small and has few identifying characteristics, so they haven't identified them. It can suggest that it might not be worth the effort to try, although having mushrooms growing in your soil is a good sign and it provides kingdom diversity, which is a good thing.

John's right, LBMs are very difficult to ID, especially from photos on the internet! But I'm guessing this one could be a member of the Parasola group:
