Yes, although a good amount of academic research and most of my personal experience has been with LSD as opposed to mushrooms. Mainly due to the increased duration and slight stimulant properties.

Nothing but good things to say about the practice provided you keep dosage and frequency at the 'micro' threshold. My roommate and I ran a pseudo-blind study (50% chance we'd get LSD on a microdose day, 50% water) and both noticed increased energy, empathy, creativity, and general quality of life.

How to Change Your Mind as someone else suggested is a great place to start.
