Hugo Zukal (1845–1900) was an Austrian lichenologist and mycologist.
Born in Troppau (now Opava in the Czech Republic), he graduated from high school there in 1859, and was afterwards employed as a botanist until 1864.
He has been credited for having introduced the term pallisade hyphae in an 1895 publication to refer to a microscopic arrangement of fungal tissue characteristic of the cortex in the lichen genus Roccella.
[2] In 1898 he became a professor of phytopathology at the University of Natural Resources and Life Sciences, Vienna.
[3] Several taxa have been named to honour Zukal.
