Johan Johnsen Havaas promoted it to distinct species status in 1918. The lichenicolous fungus, lichenicolous fungus ''Tremella tubulosae'', described as a new species in 2020, has been recorded in Scotland and Spain. It causes the formation of distinct, convex, dark brown to blackish galls on the surface of the host thallus. Chemistry ''Hypogymnia tubulosa'' contains several secondary metabolite, secondary chemicals, including four depsidones (3-hydroxyphysodic, 4-O-methyl physodic acid, physodic acid, physodic and physodalic acid), and two depsides (atranorin and chloroatranorin). Other metabolites that have been identified are atranol, chloroatranol, atraric acid, olivetol, olivetonide and 3-hydroxyolivetonide. References Hypogymnia, tubulosa Lichen spec ...

Ludwig Emanuel Schaerer
Ludwig Emanuel Schaerer (11 June 1785 – 3 February 1853) was a Swiss pastor and lichenologist.

During his career as a teacher, orphanage director, and pastor, he researched extensively and maintained correspondence with foreign botanists interested in cryptogams. Schaerer was best known for his multi-volume work ''Lichenum Helveticorum Spicilegium'' ("Anthology of Swiss Lichens"), published in 12 parts from 1823 to 1842.
