If so I have 2 Fungus related questions. One is in my outdoor square foot garden. We have mushroom/ fungus bloom... Lots and lots of these type of mushrooms. The other is mushrooms growing in our indoor plants. Is there anything we can do?

You almost named the mushroom in your first photo yourself!
According to the University of Tennessee Soil, Pest and Plant Center, "it's not unusual to spot the yellow house plant mushroom (YHPM), Leucocoprinus birnbaumii, in potted plant containers using bark or peat based substrates. The YHPM is not a plant pathogen... Other common names include the flowerpot parasol and the plantpot dapperling. Thanks to Bill Randles for sharing this image.

As with all mushrooms, including the ones in your yard, they just pop up when conditions are just right (especially in wet, humid weather) and are not of concern. Your second photo shows the aptly named "birds nest fungus".
If you don't like them, just knock or scrape them down .
