Niebla Spatulata
''Niebla spatulata'' is a fruticose lichen that grows on small rocks along the foggy Pacific Coast of central Baja California in the Sebastián Vizcaíno Bay, Vizcaíno Desert.Spjut, R. W. 1996. ''Niebla'' and ''Vermilacinia'' (Ramalinaceae) from California and Baja California. Sida Bot. Misc. 14 The epithet, '' spatulata'' is in reference to the flattened branches of the thallus, in contrast to another similar species, ''Niebla flabellata''. Distinguishing features ''Niebla spatulata '' is characterized by a fragile thallus divided into irregularly flattened tufted branches spreading from a yellowish orange pigmented holdfast, to 5 cm high and 5 cm across, and by containing the lichen substance hypoprotocetraric acid (without triterpenes but with other unknowns), and by its relatively thin cortex, 35–50(-100) μm thick, in contrast to 45–75 μm thick in ''Niebla josecuervoi'', which also differs by the cylindrical-prismatic branches. The branches of ''N. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fruticose Lichen
A fruticose lichen is a form of lichen fungi that is characterized by a coral-like shrubby or bushy growth structure. It is formed from a symbiotic relationship of a photobiont such as green algae or less commonly cyanobacteria and one, two or more mycobionts. Fruticose lichens are not a monophyletic and holophyletic lineage, but is a form encountered in many classes. Fruticose lichens have a complex vegetation structure, and are characterized by an ascending, bushy or pendulous appearance. As with other lichens, many fruticose lichens can endure high degrees of desiccation. They grow slowly and often occur in habitats such as on tree barks, on rock surfaces and on soils in the Arctic and mountain regions. Characteristics Fruticose lichens are lichens composed of a shrubby or bushy thallus and a holdfast. The thallus is the vegetative body of a lichen that does not have true leaves, stems, or roots. The thallus colour is affected by the algae in the lichen, compounds created by t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
