The Living Mushrooms have one or more mouths (often at odd angles), as well as vine-like tongues.
After emerging from underground, they overrun Camp Opinicon, capturing most of the staff and campers. The camp luckily had a large quantity of anti-athletes foot powder due to them constantly getting athlete's foot. Ben Tennyson killed the Mycelium with the powder, which killed the Living Mushrooms.
Living Mushrooms are vulnerable to anti-athletes foot powder.
If the Mycelium is killed, all the Living Mushrooms will die too.
