Rock Tripe – 10/30/18
Observer: Kathy Farrell
Observation Date: 10/30/2018
Observation Location: Mountain Street
Common Name: Rock Tripe lichen
Scientific Name: Umbilicaria mammulata
Comments: This lichen is edible (after boiling several times). It is considered to be “starvation food.” There are stories of George Washington’s troops eating it when they had nothing else. I found it in a rocky cliff area.
