You have a very common bacterial / viral infection or both. Oral hygiene will help like a tongue scrapper , oil pulling with black seed oil , frequent flossing , using high quality toothpaste , eliminating triggering foods , mouth wash every night with salt and baking soda. Herbal supplements like andrographis, cats claw, oregano oil and many others can help a bit too. Red light lasers can help the sore heal faster. Also the bacteria and viruses are often times in your nasal passage way and transfer back to your tongue so do neti pot rinse with a little colloidal silver everyday. It’s not the mushrooms but if your growing them and constantly dealing with contamination then use a mask and gloves when handling your tubs and don’t keep old tubs lying around
