What is this
Newbie to mushroom growing, found these weird spots in both my tubs. My guess is they are pins/primordia that smooshed up to the side but they also look scarily like something that would grow in agar after rubbing your anus in it. People that have been helping me learn how to grow mushrooms have no idea what it is and one of them pointed here. My FEA and lighting was poor as I had them in my closet for awhile, but ive moved them to my room where they are now getting light and peaked my lid more for more air. But what on earth is this?
