Walther Otto Müller, also Otto Müller, (20 June 1833 – 17 July 1887, in Gera) was a German botanist and gardner.[1] He was mainly interested in Cryptogamae, in particular lichen and mosses. Müller was the author of some books and several articles in scientific and botanical journals.[1] He monochrome illustrated at least one. He collected plants, lichen and mosses for herbaria to sell the exsiccates as loose-leaf-collections.[2] Several of these exsiccatae issued by him are known, among them Die Cladoniaceen von Nord-Deutschland, herausgegeben von W. O. Müller.[3][4]
The topography of the Gera region provided flora and fauna from lowland and highland at one rich spot.[1] Some of his specimens are housed at the British Museum.
