 Vermilacinia robusta

Vermilacinia robusta is an olive green fruticose lichen that occurs on rocks near ocean mist along the foggy Pacific Coast of southern California to northern Baja California and offshore islands.The epithet, "robusta", was probably adopted in recognizing a more robust form of "V. comboides", originally described as a variety of "Ramalina combeoides" by R. Heber Howe, Jr. in 1913.
