Taxonomic disagreements aside, I have run into programming "gotchas"
in the past because I did not know about generic homonyms and thus
my code was ignorant of homonyms. I was surprised then to find both
a corticioid fungus and a marine sponge with the same genus name
(Corticium is in both Carticiaceae and Plakinidae). Also a surprise
to find both a fungus and a plant with the same genus name (Virgaria).
Then a taxonomic guru told me about the genus Erica for insects/plants.
There are probably two dozen others...
