Mushrooms and lichen are neither plants nor animals. They aren’t difficult to preserve. They aren’t pressed; instead they are dried and stored in cardboard boxes or paper bags. The species is often identified by its pollen, so it is important that the specimens don’t get mixed up.

The largest collection of lichen in the Porvoo Museum collection is from the 1940s and 50s. A teacher in the Porvoo Lyceum, Börje Olsoni collected primarily plants, but he also preserved hundreds of specimens of lichen. He even inspired his student Karl-Gustav Widén, whose collection of about 350 specimens of lichen is also in the Porvoo Museum collection.
