Leucodermia Arsenei
''Leucodermia'' is a genus of lichen-forming fungi in the family Physciaceae. Taxonomy The genus was circumscribed by German lichenologist Klaus Kalb in 2015, with '' Leucodermia leucomelos'' assigned as the type species. ''Leucodermia'' includes lichens that were previously classified in genus ''Anaptychia'' section ''Polyblastidium'' series ''leucomelaenae''. The genus name combines ''leucomelaenae'' with ''Heterodermia''. Klaus included 10 species in his original circumscription of the genus; ''Leucodermia guzmaniana'' was added as a newly described species in 2019. Description Characteristics of genus ''Leucodermia'' include a thallus that is either leafy (''foliose'') to somewhat bushy (''subfruticose'') with lobes that are linear-elongate, ribbon-like, and dichotomously branched. The lobes have conspicuous, long rhizines at their margins. The thallus is loosely attached to the substrate and lacks a lower cortex. The apothecia often have pruinose discs and '' Polyblastidiu ...

Klaus Kalb
Klaus Kalb (born 1942) is a German lichenologist and an authority on tropical lichens. Biography Klaus Kalb was born in Nuremberg in 1942 and grew up in southern Bavaria. From 1960 to 1965 he studied biology, chemistry, and geography at the University of Erlangen–Nuremberg. Kalb was greatly interested in lichens and decided to pursue a doctoral degree; his thesis work was about lichen communities in the Ötztal Alps. From 1978–1981 he was a teacher at the Colégio Visconde de Porto Seguro in São Paulo, Brazil. This position afforded him the opportunity to initiate research into tropical lichens. Kalb earned his habilitation from the University of Regensburg in 1989, becoming an associate professor with that institution. In 2014, the University of Wisconsin herbarium purchased Kalb's lichen collection of 60,000 specimens for $75,000. With the acquisition of Kalb's collection, rich in tropical and European specimens, the herbarium houses about 70% of the world's know ...
