Lichens of the Samoa Peninsula
The Samoa Peninsula, a sand spit separating Humboldt Bay and the Pacific Ocean here in Northern California has a diverse and interesting lichen flora.  Nearly 150 species occur here across the landscape.  Two rare lichens in particular, Bryoria spiralifera and B. pseudocapillaris have certainly called the beach pine/sitka spruce forest home.  In fact, this is probably the largest B. spiralifera population in existance.
     The cryptogamic mats that occur out on the sand in dune mat vegetation are also interesting.  These mats are composed mainly of lichens and bryophytes, but some of these mats also have terrestrial, free-living green algae and/or cyanobacteria living in them as well.
