Niebla Lobulata
''Niebla lobulata'' is a fruticose lichen that grows on rocks in the fog regions along the Pacific Coast of Baja California, from Bahía de San Quintín to Vizcaíno Peninsula and offshore islands, Isla San Martín, and Guadalupe Island.Spjut, R. W. 1996. ''Niebla'' and ''Vermilacinia'' (Ramalinaceae) from California and Baja California. Sida Bot. Misc. 14 The epithet, ''lobulata'' is in reference to the lobed margins of the thallus branches. Distinguishing features ''Niebla lobulata'' is distinguished by a thallus divided into mostly strap-shaped branches from a basal holdfast, the branches not more than 20 in number, wide spreading above a short tapered and narrow base, occasionally dividing into similar branches, the branch margins often wavy (undulate), and/or lobed, or lacerated, the whole thallus not more than 7 cm high. The species (''N. lobulata'') also recognized by containing sekikaic acid (with triterpenes), and by a relatively thin cortex, (0-)35–75(-100) ...

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] |
