In 1907, Wilhelm Zopf identified and classified about 150 lichen products. Seventy years later, this number had risen to 300, and by 1995, 850 lichen products were known; [8] as of 2021, more than 1000 have been identified. [9] Analytical methods were developed in the 1970s using thin-layer chromatography for the routine identification of ...
Ramalina menziesii, the lace lichen or fishnet, is a pale yellowish-green to grayish-green fruticose lichen. It grows up to a meter long, hanging from bark and twigs in a distinctive net-like or lace-like pattern that is unlike any other lichen in North America. [ 3 ]
A lichen is a composite organism consisting of a fungus (the mycobiont) and a photosynthetic partner (the photobiont or phycobiont) growing together in a symbiotic relationship. One classification of Sierra Nevada lichens is according to functional groups, by the National Park Service. [1] These functional groups overlap with each other.
Initially, it was considered an unusual lichen metabolite as it did not clearly belong to any of the known structural categories of lichen products at that time. [1] Unlike plant-derived xanthones which typically have 1,3,5- or 1,3,7-trihydroxy patterns, thiophanic acid features a characteristic 1,3,6-trihydroxy-8-methylxanthone structure that ...

Ramalina leptocarpha, also known as the western strap lichen, is a species of cartilage lichen found in Oregon, California, and Baja California. [1] [2] [3] The range of this species extends from the coast as far inland as the Sierra Nevada mountain range. [2] R. leptocarpha often grows in epiphytic association with Ramalina menziesii. [4]
Enchylium polycarpon, commonly known as the shaly jelly lichen, is a species of foliose lichen in the family Collemataceae. Formerly known as Collema polycarpon, it was renamed in 2013 following a taxonomic revision. This lichen has a widespread global distribution, occurring in various regions of North America, Europe, Africa, and Asia.
Usnea filipendula, the fishbone beard lichen, is a pale gray-green fruticose lichen with a pendant growth form, growing in up to 20 cm many-branching tassels hanging from the bark of trees. [2] In California, it mostly grows on mostly conifer in the Coast Range, but also in the western slopes of the Sierra Nevada range. [2]: 206 It lacks ...
