The lichen collection consists of samples collected in Israel and in other countries. The material is kept in a dry state in paper envelopes, with details about site and date of collection.In addition, we have a lichen collection for teaching purposes and demonstrations, which includes examples of crustose, foliose and fruticose thalli. We have also a collection of living lichens located outdoors, near the green house of the palm collection. These lichens are replaced from time to time by fresh samples brought from different regions of Israel.
