After starting as a librarian, in 1958 she became curator of the lichen collections, assuming a position previously held by prominent Hungarian lichenologist Ödön Szatala.
[3] As part of her work in the lichen herbarium, Verseghy curated the extensive collections of Ferenc Fóriss, Vilmos Kőfaragó-Gyelnik and Szatala in the classification system proposed by Alexander Zahlbruckner.
An additional 1,500 specimens were from abroad–Finland, Norway, Poland, Romania, Slovakia, Sweden, Turkey and Ukraine were collecting destinations.
Between 1969 and 1981 she issued two exsiccatae, namely Lichenotheca parva and Lichenes exsiccati, editi a sectione botanica musei historico-naturalis Hungarici.
[4][5] She published more than a hundred scientific and popular papers mainly on floristics, taxonomy, plant physiology, and bioindication.
