Heterodermia Fragmentata
''Heterodermia fragmentata'' is a species of corticolous (bark-dwelling) foliose lichen in the family Physciaceae. It occurs in Sri Lanka. Taxonomy ''Heterodermia fragmentata'' was formally described and published by lichenologists Gothamie Weerakoon and André Aptroot 2015. The type specimen was collected by both authors in Nuwara Eliya, Sri Lanka, on the bark of a tree. Description The species has a foliose (leafy) thallus, forming tufts up to 7 cm in diameter, with linear, grey up to 1 cm long and 0.7–2.2 mm wide. The tips of these lobes are often slightly and spotted with white . The lobes have margins with a thin dark grey line, while the lower surface is , white, and often blackens towards the centre. It features black, shiny, mostly simple (unbranched) up to 3 mm long. The lichen reproduces through , which are rare, stipitate, and on the upper surface of the thallus lobes. These apothecia develop tapering lobes around their margins, with a brow ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gothamie Weerakoon
Gothamie Weerakoon () is a Sri Lankan-based botanist, lichenologist and environmentalist. Early life and education Weerakoon's passion for the environment was initiated during her childhood, which she spent largely outdoors, inspired by her cousin and the natural surroundings of Diyatalawa, where she lived due to her father's military occupation. Her early education further cemented her connection to the environment, providing her with foundational knowledge about local flora and the changing seasons. This early exposure to nature deeply influenced her future academic and career choices. After completing her primary education at the Devi Balika Vidyalaya in Colombo, she attended the University of Sri Jayewardenepura, completing her PhD in 2013. Her PhD research, conducted primarily in the Knuckles Mountain Range, involved studying the activity of lichens across different habitats and establishing a comprehensive lichen checklist for the area. She emerged as the most active Sri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atranorin
Atranorin is a chemical substance produced by some species of lichen. It is a secondary metabolite belonging to a group of compounds known as depsides. Atranorin has analgesic, anti-inflammatory, antibacterial, antifungal, cytotoxic, antioxidant, antiviral, and immunomodulatory properties. In rare cases, people can have an allergic reaction Allergies, also known as allergic diseases, are various conditions caused by hypersensitivity of the immune system to typically harmless substances in the environment. These diseases include Allergic rhinitis, hay fever, Food allergy, food al ... to atranorin. References Further reading * * * * Polyphenols Lichen products {{organic-compound-stub ...

Lichens Of Sri Lanka
A lichen ( , ) is a hybrid colony (biology), colony of algae or cyanobacteria living symbiotically among hypha, filaments of multiple fungus species, along with yeasts and bacteria embedded in the cortex or "skin", in a mutualism (biology), mutualistic relationship.Introduction to Lichens – An Alliance between Kingdoms . University of California Museum of Paleontology. . Lichens are the lifeform that first brought the term symbiosis (as ''Symbiotismus'') into biological context. Lichens have since been recognized as important actors in nutrient cycling and producers which many higher trophic feeders feed on, such as reindeer, gastropods, nematodes, mites, and springtails. Lichens have properties different from those of their component organisms. They come in man ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
