Lepraria
''Lepraria'' is a genus of leprose crustose lichens that grows on its substrate like patches of granular, caked up, mealy dust grains.A taxonomic revision of the North American species of Lepraria s.l. that produce divaricatic acid, with notes on the type species of the genus L. incana, James C.

There are no known mechanisms for sexual reproduction, yet members of the genus continue to speciate. Some species can form marginal lobes and appear squamulose.

Lepraria Incana
''Lepraria incana'' is a species of dust lichen in the family Stereocaulaceae. First described scientifically by Johann Jacob Dillenius in 1741, and then formally by Carl Linnaeus in 1753, it is the type species of the genus ''Lepraria''. The thallus of this species is green to greyish-green, and powdery – as if made of tiny granules. These granules are soredia, which are asexual reproductive structures. Like most members of genus ''Lepraria'', the lichen has few distinguishing features, lacking both a medulla and sexual reproductive structures (apothecia). Chemically, the lichen is characterised by the presence of the secondary chemicals known as divaricatic acid and zeorin. The lichen prefers to grow on bark on the base of trees in moist and partly shaded locations, but will also grow on dead wood, silica-rich rocks, or soil. It is not particularly selective in terms of its bark substrate, and has been recorded growing on a wide variety of both deciduous and conifero ...

Jack Laundon
Jack Rodney Laundon (28 July 1934 – 31 December 2016) was a British lichenologist and became President of the British Lichen Society. Education and personal life Jack Rodney Laundon was born 28 July 1934 in Kettering, Northamptonshire. He was educated at Park Road School, Kettering Central School and Kettering Grammar School, and then worked at the British Museum (Natural History) from 1952 - 1990, mainly in the lichen section. He married Rita June Bransby in 1958 and they had one daughter. He died 31 December 2016. Career He was interested in lichen from his teens, and developed his interests in lichen ecology and taxonomy as well as the specimen curation and identification required by his post. This included curating the collection of specimens from Erik Acharius held at the Museum. He helped establish the use of chemotaxonomy for lichens at the Museum and was active in verifying specimens sent to the Museum. His application of the ''International Code of Botanical Nomencla ...
