Finnish botanists and mycologists have studied Arctic areas and timberline regions since the beginning of the 18th century. Most expeditions to the Kola Peninsula were made between 1800 and 1917 and until 1945 to Lapponia petsamoënsis on the western rim of the Kola Peninsula. Since those years, these areas have been part of the Soviet Union or Russia. Svalbard and Newfoundland and Labrador have been studied repeatedly as well, Svalbard since the 1860s and Newfoundland and Labrador since the 1930s. This article focuses on Finnish collections. These are deposited in the herbaria of Helsinki, Turku, and Oulu universities, except materials from the Nordenskiöld expeditions, which were mainly deposited in Stockholm. Concerning the Kola Peninsula, collections at Helsinki are the most extensive. The exact number of specimens is not known, but by rough estimation, the number is about 60 000, with an additional 110 000 observations included in the database. These expeditions have provided material to describe 305 new taxa to science, viz. 47 algae, 78 bryophytes, 25 fungi, 136 lichens, and 19 vascular plants. This number is an underestimate, as many new species have been described in several separate taxonomic articles. At least 63 persons have contributed to making these collections to Finnish herbaria. Of those, 52 are of Finnish nationality.Key words: bryophytes, fungi, vascularplants, Finnish, Arctic.Résumé : Les botanistes et les mycologues finlandais ont étudié les régions arctiques et les régions de limite forestière depuis le début du 18 ème siècle. La plupart des expéditions à la presqu'île de Kola ont été faites entre 1800 et 1917 et jusqu'à 1945 à Lapponia petsamoënsis sur la côte ouest de la presqu'île de Kola. Depuis ces années, ces régions ont fait partie de l'Union soviétique ou de la Russie. Svalbard, Terre-Neuve et le Labrador ont été étudiés à plusieurs reprises aussi, Svalbard depuis les années 1860 et Terre-Neuve et le Labrador depuis les années 1930. Cet article porte sur les collections finlandaises. Celles-ci sont dépo-sées dans les herbiers des universités de Helsinki, de Turku et d'Oulu, sauf le matériel des expéditions Nordenskiöld qui a été principalement déposé à Stockholm. En ce qui concerne la presqu'île de Kola, les collections à Helsinki sont les plus vastes. On ne connaît pas le nombre exact de spécimens, mais par l'estimation approximative le nombre est environ 60 000, avec 110 000 observations supplémentaires comprises dans la base de données. Ces expéditions ont fourni le matériel qui a servi à décrire 305 nouveaux taxa pour la science, à savoir 47 algues, 78 bryophytes, 25 champignons, 136 lichens et 19 plantes vasculaires. Ce nombre est une sous-estimation, puisque de nombreuses nouvelles espèces ont été décrites dans plusieurs articles taxonomiques. Au moins 63 personnes ont contribué à la création de ces collections aux herbiers finlandais. De ce nombre 52 sont de nationalité finlandaise.

Driftwood is woody debris that is floating on the sea or brought onto the shore by the sea. It can have a natural origin but often it originates from human activities. Driftwood has a significant ecological role as a microhabitat for a large range of species. Dead‐wood‐associated aphyllophoroid fungi on driftwood have been studied rather little globally, and there are hardly any studies conducted in the Baltic Sea. We studied the diversity and ecology of polypores and corticioids growing on driftwood (man‐made logs) on the shores of the Finnish SW‐archipelago. In total, 394 driftwood logs were surveyed for visible fungal sporocarps. We found altogether 145 species (1023 records) of which approximately three‐fourths were corticioids. The driftwood logs hosted several rare and noteworthy species, such as one new corticioid species, 16 nationally rare species, and 40 new species to the region. The five most common species accounted for one‐third of all observations, whereas 82 species (11% of all records) were recorded only once or twice. Larger logs hosted, on average, more species compared to small‐diameter logs. The mean number of species increased significantly when comparing the logs in the first and the middle stages of decay. Our results show that driftwood logs can host a wide variety of species and they provide an important substrate for many dead‐wood‐associated fungi, including species of conservation concern and species with restricted ecological requirements. Driftwood hosted several species that have not been previously found in the archipelago forests, and the logs clearly enrich the fungal diversity in the area. Our results encourage to increase dead wood for fungi in coastal forests where it has been dramatically decreased as a result of strong hemeroby.
