I’m trying a new layout and I decided to rock the sticky post. This little mushroom was out front at work in August sometime. It’s Laccaria amethystina. What you want to know the common name??? I have no clue. Common mushrooms have multiple common names which confuses things and then most don’t have any. So, if you really get into learning fungi, your best bet is to learn Latin… or for fungi even some Greek. Many scientific names of fungi are derivatives of Greek words.
