Biatora Chrysanthoides
''Biatora chrysanthoides'' is a species of corticolous (bark-dwelling), leprose lichen in the family Ramalinaceae. It is found in Norway, the Pacific Northwest of northern North America, Sweden, and Russia. It was formally described as a new species in 2003 by the lichenologists Christian Printzen and Tor Tønsberg. It contains gyrophoric acid in both the thallus and the apothecia (fruiting bodies), resulting in a C+ (quickly reddish) chemical spot test reaction. Its are 9.3–10.7 by 3.2–3.3 μm The micrometre (Commonwealth English as used by the International Bureau of Weights and Measures; SI symbol: μm) or micrometer (American English), also commonly known by the non-SI term micron, is a unit of length in the International System ....

Tor Tønsberg
Tor Tønsberg (born 1948 in Oslo) is a Norwegian lichenologist who has made significant contributions to the taxonomy, chemistry, floristics, and phytogeography of lichens and lichenicolous fungi. Throughout his career, he has described more than one hundred species and genera new to science, advancing the knowledge of lichens in Europe and North America. Early life and education Tønsberg grew up in Bekkelagshøgda, Nordstrand, in the eastern part of Oslo. He developed an early interest in nature, frequently visiting the nearby lake Østensjøvannet and the forests of Østmarka with his younger brother Knut. His systematic nature and passion for collecting began in childhood, where he organized a "museum" in the basement of his parents' house. Summers at his family's farm, Myrvang, in Majavatn in Grane Municipality in northern Norway, also played a significant role in fostering his love for the natural world. His grandfather, a frequent companion on hikes and fishing tours ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biatora
''Biatora'' is a genus of lichens in the family Ramalinaceae. Originally circumscribed in 1817,Fries EM, Sandberg A. (1817). ''Lichenum dianome nova''. Lund. the genus consists of crustose and squamulose lichens with green algal photobionts, biatorine apothecia, colorless, simple to 3-septate ascospores, and bacilliform pycnospores. Description ''Biatora'' species are crustose lichens with a spreading () thallus that may appear thin and somewhat membranous in places. The surface is often cracked () and, in species that grow in association with mosses, may be or warted. The thallus is typically creamy white, dull green, glaucous green, or green-grey and lacks a distinct outer protective layer (). Some species produce soredia, small reproductive that facilitate dispersal. A , the initial fungal layer that some lichens form before developing a full thallus, is absent. The photosynthetic partner () is a alga, a group characterized by spherical to broadly ellipsoidal cells. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lichens Of Eastern Europe
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] |
