It is rare in California, but is slightly more common in northern forests. The lichen consists of very long (up to 10 feet) strands with short even side branches and it festoons tree branches. It may have been the inspiration for tinsel on Christmas trees.https://doctorfern.org/wp-content/uploads/2014/04/usnea-rubicunda.jpgUsnea rubicundaThis is red beard lichen (Usnea rubicunda). Unlike the old man's beard (pictured below), this lichen is more shrubby and more red in color. It is commonly found on branches of oaks and conifers in Pacific Northwest forests.https://doctorfern.org/wp-content/uploads/2014/04/loxosporopsis-corallifera.jpgLoxosporopsis coralliferaLoxosporopsis corallifera is only known from Alaska down to the coast of Northern California. With the discovery in Muri Woods, the known geographic range for this species may need to be expanded. It is a small lichen that is firmly attached to the bark and it consists of many small "spaghetti strands" called isidia that serve to disperse the lichen by breaking off and inhabiting new locations.https://doctorfern.org/wp-content/uploads/2014/04/ramalina-menziesii.jpgRamalina menziesiiLace lichen (Ramalina menziesii) is very appropriately named since its branches have net-like perforations. This greatly enhances the surface area and enables it to better absorb moisture and nutrients from the air. It is mainly found in the fog belt along the coast. It has been proposed as the state lichen of California, so it may soon obtain the same recognition as California poppy (state flower), black bear (state animal), and not least coast redwood (state tree).https://doctorfern.org/wp-content/uploads/2014/04/calicium-abietinum.jpgCalicium abietinumThis is a pin lichen (Calicium abietinum) — a tiny lichen that has a powdery mass of spores on top of a stalk. You need a hand lens to really see them since they are only 0.02-0.03 inches tall. This species is fairly common, but other pin lichens are very rare and only found in old-growth forests, like Calicium sequoiae.https://doctorfern.org/wp-content/uploads/2014/04/ramalina-menziesii-blog.jpgRamalina menziesii-blogLace lichen (Ramalina menziesii)https://doctorfern.org/wp-content/uploads/2014/04/calicium-abietinum-blog.jpgCalicium abietinum-blogPin lichen (Calicium abietinum)2014-11-21T19:49:14+00:00monthlyhttps://doctorfern.org/2014/11/21/rain-creates-colorful-mushroom-show/https://doctorfern.org/wp-content/uploads/2014/11/coral-fungus-yellow-jsrsp-copy.jpgCoral fungus-yellow-JSRSP copyhttps://doctorfern.org/wp-content/uploads/2014/11/coral-fungus-white-jsrsp.jpgCoral fungus-white-JSRSPhttps://doctorfern.org/wp-content/uploads/2014/11/coral-fungus-red-jsrsp-copy.jpgCoral fungus-red-JSRSP copyhttps://doctorfern.org/wp-content/uploads/2014/11/coral-fungus-orange-jsrsp-copy.jpgCoral fungus-orange-JSRSP copyhttps://doctorfern.org/wp-content/uploads/2014/11/jsrsp-11-13-2014-boy-scout-tree-trail.jpgJSRSP-11.13.2014 Boy Scout Tree TrailSun streaming into rain-soaked woods at Jedediah Smith.2014-11-21T19:24:13+00:00monthlyhttps://doctorfern.org/2014/11/07/protecting-plantings/2014-11-07T18:58:22+00:00monthlyhttps://doctorfern.org/2014/10/07/chronicle-covers-the-drought/https://doctorfern.org/wp-content/uploads/2014/10/sfgate-front-page.pngSFgate front pageClick here for the full article by Kurtis Alexander.2014-10-07T22:52:27+00:00monthlyhttps://doctorfern.org/2014/10/07/memorial-park-bioblitz/https://doctorfern.org/wp-content/uploads/2014/10/fern.jpgFernhttps://doctorfern.org/wp-content/uploads/2014/10/slug-and-mushrooms.jpgSlug and mushroomshttps://doctorfern.org/wp-content/uploads/2014/10/me-and-deborah.jpgMe and Deborahhttps://doctorfern.org/wp-content/uploads/2014/10/creeping-moss.jpgCreeping mosshttps://doctorfern.org/wp-content/uploads/2014/10/bioblitz-volunteers.jpgBioblitz volunteershttps://doctorfern.org/wp-content/uploads/2014/10/inat-bioblitz.pngiNat Bioblitz2014-10-07T19:45:04+00:00monthlyhttps://doctorfern.org/2014/10/07/nature-is-speaking-robert-redwood-is-the-redwood/https://doctorfern.org/wp-content/uploads/2014/10/screen-shot-2014-10-07-at-12-14-47-pm.pngNature is Speaking2014-10-07T19:20:39+00:00monthlyhttps://doctorfern.org/2014/10/07/green-cones-go-red/https://doctorfern.org/wp-content/uploads/2014/10/water-and-cones.jpgWater and conesTo see the green cones go red, just grab a glass of water.https://doctorfern.org/wp-content/uploads/2014/10/tannins-dissovling.jpgTannins dissovlingTannins begin to dissolve as soon as the green redwood cones get wet.https://doctorfern.org/wp-content/uploads/2014/10/dissolved-tannins.jpgDissolved tanninsGreen cones leach tannins into a glass of water, turning it a lovely shade of red.https://doctorfern.org/wp-content/uploads/2014/10/green-redwood-cone.jpgGreen Redwood ConeRedwood seeds hidden within this green cone won't join the forest seed bank because the cone fell off the tree too soon.https://doctorfern.org/wp-content/uploads/2014/10/green-cone-crop.jpgGreen cone cropGreen redwood cones abound on the forest floor this fall.2014-10-07T19:08:01+00:00monthlyhttps://doctorfern.org/2014/09/26/beautiful-from-a-safe-distance/https://doctorfern.org/wp-content/uploads/2014/09/2013-11-10-12-40-19.jpgRed poison oakIt's hard to hate a beautiful plant like poison oak, especially in the fall.https://doctorfern.org/wp-content/uploads/2014/09/2013-11-10-12-37-10.jpgRed and green contrastRed poison oak leaves contrast to the brilliant year-round green sword fern fronds. https://doctorfern.org/wp-content/uploads/2014/09/2013-11-10-12-34-43-1.jpgPoision oak autumn colorsPinks, reds, and yellows emerge as poison oak prepares to shed its leaves for the year.2014-09-26T21:54:57+00:00monthlyhttps://doctorfern.org/2014/09/24/whats-possible-un-climate-summit/https://doctorfern.org/wp-content/uploads/2014/09/screen-shot-2014-09-24-at-10-02-15-am.pngScreen shot 2014-09-24 at 10.02.15 AM2014-09-24T17:06:09+00:00monthlyhttps://doctorfern.org/2014/09/23/ferns-welcome-las-positas-students/2014-09-23T22:33:01+00:00monthlyhttps://doctorfern.org/2014/09/17/redwood-weather/https://doctorfern.org/wp-content/uploads/2014/09/montgomery-woods_baxter-with-treetop-fog-collector.jpgMontgomery Woods_Baxter with treetop fog collectorWendy Baxter with treetop fog collector at Montgomery Woods State Natural Reserve.
