Brief Introduction to Lichens

Lichens are dual organisms that consist of both an alga (or cyanobacterium) and a fungus. Because they consist of two unrelated organisms that live together intimately, lichen fungi and algae are good examples of symbiotic organisms. Lichens come in a wide range of colors from orange to chartreuse to black and white. They look like small plants or like fungi growing on bark, wood, soil or rock. The alga is photosynthetically active and provides food for the fungus. The fungus forms the shape of the lichen and provides an hospitable environment in which the alga can grow. With a light microscope and a thin cross section of a lichen, you can see how the filamentous fungal cells wrap themselves around the tiny individual algal cells. The zones of contact between the two organisms are thought to be the site of food transfer.

 

 

 

UCSC Lichen List


Tonya Haff (UCSC Museum of Natural History Collections), Judy Robertson and Bill Hill
(California Lichen Society) look at lichens on fence posts near the base of campus.

In the Spring of 2004, the UCSC Museum of Natural History Collections invited the California Lichen Society to do a survey of UCSC campus lichens. Portions of the campus surveyed include the areas around the Barn Theater and Cook House parking lots, the redwood fences west of the Blacksmith Shop, trees at the base of the bike path, the Farm and Garden Gatehouse, the Upper Quarry, the meadow below the Academic Resources Center, the North Perimeter parking lot, and some of the chaparral of upper campus. The lichen society volunteers collected over 150 different lichens in two days. Collections of most of the species are available in the museum. Below is a list of the lichens that they identified. Many thanks to the California Lichen Society for their donation of time and effort to document the species of the UCSC campus.
