Parmelia Subrudecta
''Punctelia subrudecta'' is a species of foliose lichen in the family Parmeliaceae. Originally described in 1886 as ''Parmelia subrudecta'', it was transferred to the genus ''Punctelia'' in 1982. For much of the twentieth century, North American specimens were misidentified as this species, until molecular phylogenetics studies in 2010 revealed that they represented three distinct species, restricting the true ''P. subrudecta'' to Old World populations. The lichen forms loosely attached rosette (botany), rosettes with narrow, pale grey-green and is distinguished by its pale underside, fine powdery reproductive structures (soredia), and distinctive hook-shaped conidia. It is found primarily in temperate and Mediterranean climate, Mediterranean woodlands of Europe, Macaronesia, and parts of North and East Africa, where it grows on tree bark and occasionally on rock surfaces.

Hildur Krog
Hildur Krog (22 March 1922 – 25 August 2014) was a Norwegian lichenologist and university professor who made contributions to the field of lichenology, particularly in the areas of lichen taxonomy (biology), taxonomy, chemotaxonomy, and floristics. Biography Hildur Krog was born on 22 March 1922 in Søre Simostrada, Modum, Norway. She received her early education at the landgymnas (rural high school) in Voss, Hordaland. During World War II, in late April 1940, she experienced German airstrike, air raids on Voss and fled to the mountains with her sister, where they reportedly nearly starved. In 1941, she completed her high school examination (Abitur) and began studying biology at the University of Oslo. In 1946, she returned to her studies after the Norwegian scholar Eilif Dahl, who had secured a position as a university lecturer in Oslo, came back from England. Dahl had been a member of a Norwegian resistance movement, Norwegian resistance group during the war and had been fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
