Opegrapha Ochrocheila
''Alyxoria ochrocheila'' is a species of lichen in the family Lecanographaceae ''Lecanographaceae'' is a family of mostly lichens (also some lichenicolous fungi) in the order Arthoniales. The family was circumscribed in 2014, prompted by a molecular phylogenetic-based restructuring of the Arthoniales. Taxonomy The fami .... It has a cosmopolitan distribution, and was species description, formally described by William Nylander (botanist), William Nylander in 1865. Description ''Alyxoria ochrocheila'' has an effuse thallus, lacks a prothallus, and is white to white-grey in colour. It is often mistaken for ''Opegrapha'' sp., but can be identified due to having distinct orange pruina that turn purple when spot-tested with potassium hydroxide. Taxonomy The species was first described by William Nylander (botanist), William Nylander in 1865, under the name ''Opegrapha ochrocheila''. It was recombined in 2010 and placed in the genus ''Alyxoria'' by Damien Ertz and Anders ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
William Nylander (botanist)
William (Wilhem) Nylander (3 January 1822 – 29 March 1899) was a Finnish botanist and entomologist. Nylander was born in Oulu, and taught at the University of Helsinki before moving to Paris, France, where he lived until his death in 1899. Nylander studied medicine, receiving a degree in 1847. Nylander pioneered the technique of determining the taxonomy of lichens by the use of chemical reagents, such as potassium hydroxide, tinctures of iodine and calcium hypochlorite, still used by lichenologists as the K and C tests. Nylander was the first to realise the effect of atmospheric pollution on the growth of lichens, an important discovery that paved the way for the use of lichens to detect pollution and determine the cleanness of air. His brother Fredrik Nylander was also a botanist. Nylander was one of the most prolific authors of new fungal and lichen species, having formally described about 3700 in his career. He edited the exsiccata Exsiccata (Latin, ''gen.'' -ae, ' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
