I think this is Ophiostoma novo-ulmi, the fungus which causes Dutch Elm Disease.

my ex
could identify trees
from a good distance
#elm
no bother she'd say
her mother
taught her apparently
to identify trees
handy I suppose
if you're a tree doctor
Dutch Elm Disease
what's your prognosis
Ophiostoma novo-ulmi
affects the trees
ability to
transport water
leading to death

Johanna Westerdijk was the first #female #professor in the Netherlands at a time when very few women had a place in #science.
Together with her two PhD students Marie Beatrice Schwarz and Christine Buisman, she identified #Ophiostoma ulmi as the #fungus responsible of the #DutchElmDisease.
