The cryptogamic section curates the collections of algae, bryophytes, fungi, lichens and ferns of the Herbarium Senckenbergianum (FR).
One focus of the collections are lichens, which are represented by important historical herbaria, e.g. J. A. Metzler, L. P. K. Scriba. Our research is also focussed on lichens.
Besides systematics and phylogeny, we investigate the biogeography and symbiotic interactions of lichens using microscopical, microchemical and molecular genetic methods.
