Marie-Agnès Letrouit-Galinou

Marie-Agnès Letrouit-Galinou (née Galinou; born 1931) is a French botanist, mycologist, and lichenologist, known for her contribution to revolutionizing the scientific understanding of ascomycete development and classification. By the mid-1970s electron microscopic studies confirmed their research. Later in her career she did research on the effects of air pollution on lichens and stimulated other French lichenologists to do such research.

Letrouit-Galinou not only promoted lichenology in France, but also did her research with extremely limited financial resources. She and her collaborators had to work with quite inexpensive microscopes. The three women of the "gang of four" painted the walls of their laboratory because they had no funds to hire professional wall painters. When she retired in August 1999 from the CNRS, she donated her library to the Muséum national d'histoire naturelle.
