Biography
Petter Adolf Karsten (16 February 1834 – 22 March 1917) was a Finnish mycologist known as the leading expert on Finnish fungi during his life. Born in Merimasku, near Turku on Finland's southwestern coast, Karsten became one of the most prolific fungal taxonomists of the nineteenth century, earning the nickname 'father of Finnish mycology' for his detailed scientific work over many decades.
Karsten studied at the University of Helsinki, where he gained the botanical and scientific knowledge for his future research. After completing his studies, he moved to Tammela in the Häme province, where he spent most of his life. He took a teaching job at the Mustiala Agriculture Institute, now part of the HAMK University of Applied Sciences, tying his teaching in botany with ongoing field research and specimen collection.
Throughout his career, Karsten described about 200 new genera and 2,000 new species of fungi, ranking him among the most productive mycologists of his time worldwide. He built a large scientific collection through both his fieldwork and through networks with collectors and scientists across Europe. From 1861 to 1870, he edited the exsiccata series Fungi Fenniae exsiccati, also known as Samling af Finska svampar, which was a numbered collection of dried fungal specimens that reached 1,000 entries and became a vital reference for his peers and those who followed.
Karsten stood out not only for the amount of his taxonomic work but also for his approach. He made extensive use of microscopes in his studies, helping advance the scientific understanding of fungi at a time when such methods weren't commonly used in mycology. He was a pioneer in fungal microscopy, which allowed him to describe species with great accuracy. His contributions to science and education were formally recognized with the title of Professor.
Before Fame
Petter Adolf Karsten was born on February 16, 1834, in Merimasku, a rural coastal area near Turku, in what was then part of the Grand Duchy of Finland under Russian rule. Growing up surrounded by the forests and wetlands of southwestern Finland, he had lots of early exposure to the natural world, which later became the focus of his life's work. He attended the University of Helsinki, Finland's main university at the time, where he studied botany and natural history.
After finishing his education, Karsten moved to Tammela, an area rich in agriculture, which greatly influenced his scientific work. The forests of Häme provided a great setting for studying fungi, and his job at the Mustiala Agriculture Institute gave him the stability to conduct long-term research. His early work in the 1860s, including editing the Fungi Fenniae exsiccati series, quickly earned him a strong reputation among European botanists and mycologists, establishing him as a leading expert on Finnish fungi.
Key Achievements
- Described approximately 200 new genera and 2,000 new species of fungi, representing one of the largest taxonomic outputs of any mycologist in the nineteenth century.

- 02.The international journal of mycology Karstenia, published by the Finnish Mycological Society, was named in his honor and continues to bear his name today.
- 03.He edited the exsiccata series Fungi Fenniae exsiccati between 1861 and 1870, producing a standardized collection of 1,000 numbered dried fungal specimens used as scientific references across Europe.
- 04.Karsten spent the majority of his long life—he lived to the age of 83—in the inland town of Tammela, far from major scientific centers, conducting research largely through correspondence and independent fieldwork.
- 05.His pioneering use of the microscope to study fungal structures helped transform mycology from a discipline reliant on gross morphology into one grounded in cellular and microscopic examination.
