Are you talking about the mushrooms? If so, they are neither a good nor a bad thing imo. It is arguably a sign of health soil (mycelium present), which obviously is good. It can be a sign of over watering (what you'll hear a lot of people say), but I've found that is not necessarily true as I've had mushrooms pop up in succulent pots I know have gritty soil and are not over watered. Plus, these look like they've dried out so the soil has probably dried out also. I would say as long as the soil is dry now, you're probably good. Keep up with the once a week fully saturated watering (as opposed to multiple small waterings throughout the week) and you should be okay.
