Hermann Edward Hasse (12 January 1836 – 29 October 1915) was an American lichenologist.
[1][2] He wrote two important texts and numerous articles in his field.
[3] Hassea, which is a genus of fungi in the class Dothideomycetes,[4] and Lecidea hassei, a lichen that grows inside solid rock (endolithic lichen), were both named in his honor.
His correspondents included cryptogamic botanist William Gilson Farlow and lichenologist George Knox Merrill.
[1] Lichenologist Kerry Knudsen described it as "historic" in the lichenology journal Opuscula Philolichenum.,[1] written by Hermann Edward Hasse.
