The main task of the herbarium is to gain knowledge of the world’s plant, fungi, moss, lichen and algae species by collecting, storing and examining specimens. This also ensures the existence of an archive for present and future biodiversity research, and maintains and broadens taxonomic know-how in Finland.
The herbarium collections (international herbarium code TUR) are primarily meant for research, but are also used in teaching and public decision-making. They are actively used by scientists throughout the world, and the thousands of type specimens, for example, are actively lent to other institutions for biodiversity inventories. The herbarium maintains an extensive library of taxonomic and floristic literature. We train PhD students who will become the taxonomic specialists of the future, offer identification services, and also maintain and document the collections of Åbo Akademi (herbarium code TUR-A). Scientists at the herbarium have modern laboratory facilities and equipment, which also allow molecular systematic studies.
Identification of indoor moulds
We identify indoor moulds for a fee. Before sending samples we recommend contacting Seppo Huhtinen (tel. +358 50 401 1849 or +358 40 516 2662), to make sure the samples are taken and transported appropriately. The following details need to accompany a sample:
- address or identifier of the building
- who took the sample
- who sent the sample
- what structure (material) the sample comes from
- when the sample was taken
- billing address
- business ID if appropriate (businesses)
The cost of analysis is 135 euros (+ VAT). It can include a maximum of four subsamples. Larger sample sizes cost extra. The samples should be packed in a way which allows ventilation, e.g. preferably not in a plastic bag unless this has been requested. Shipping ONLY via the post, e.g. as a regular parcel. The shipping address for samples is:

Instructions for researchers
Much of the tropical vascular plant material has been treated with ethanol when collected, and extracting DNA from these specimens does not appear to be possible. However, a part of some specimens has been kept separate and dried in silica gel. These specimens are available for molecular research by agreement.
Specimens on loan should be treated appropriately, and the use of chemical pesticides is not allowed. No markings should be made on the sheets or specimen envelopes; instead, separate handwritten or printed labels should be appended. Do not glue them in place or otherwise attach them.
On returning a loan, we ask that you send copies of publications citing the specimen, the accession number of any DNA sequences (in e.g. GenBank), and copies of any images of slides.
The herbarium collections can be studied on location. Visits should be agreed in advance.

Collecting herbarium specimens
If you plan to collect specimens for the herbarium, please contact the herbarium staff, preferably before going out to the field. This will ensure the specimens are correctly collected and reach us in good condition. When collecting abroad, please note the Nagoya Protocol and any other permits.
Observations of rare or endangered mosses should (with some exceptions) be verified by sending a sample to a herbarium. Instructions (in Finnish) are in an article published in Lenninsiipi.
Fungi specimens donated to the herbarium should (apart from the normal collecting details) include details on freshly collected characters such as taste and smell. We strongly advise taking a photograph of the fresh specimen.
Instructions on how to collect vascular plants can be found in most Floras. Finnish speakers can use “Retkeilykasvio”.
We prefer to receive details on the collecting event in electronic format, ideally in an Excel that can be directly uploaded to the collection management database.
Visitors and general public
There are no public exhibits at the herbarium. We can, however, give a guided tour of the herbarium to groups. Botanically inclined visitors are strongly recommended a trip to the university’s botanical garden in Ruissalo.
Identification of specimens and reporting observations
We are more than willing to identify small amounts of plants and fungi brought to us. We take a fee for identifying larger amounts, and for identifying indoor moulds or plant samples from e.g. archeological excavations or shipwrecks.
These sites also offer help in identifying species.
The herbarium accepts old plant collections. These are not immediately added to the herbarium’s scientific collections; instead, the staff checks each specimen’s condition and scientific value. It is common for only a few percent of e.g. old school herbaria to be included in the collections. However, grandma’s old school project may prove unexpectedly valuable, e.g. in studying the variability of cereals in the past or the historical water quality of a lake.
