The edible, wood-decaying mushroom Kuehneromyces mutabilis was studied in 3 years' culture experiments in a climate-controlled greenhouse. Pre-incubated wood blocks and sawdust cylinders were buried in soil in test buckets. Tested variables included inter-strain variation, inoculation methods, wood disinfection, dimensions of wood blocks and mixtur...

Mistletoe (Viscum album) has during the 2010’s been spreading in the vicinity of Turku (Varsinais-Suomi, Finland). This is the first known fertile V. album population within the country. The situation in 2018 is mapped here, with a review of the biology and dispersal of this hemi-parasitic species. V. album was found at 48 locations, with the total...

Inventories on threatened bryophytes, lichens and polypores of Ruissalo island (Turku, Finland) in 2014-2015. In Finnish.

Ten species of mosses (Bryophyta: Entosthodon obtusus, Entosthodon ulvinenii, Eurhynchiastrum diversifolium, Hedwigia emodica, Hedwigia mollis, Hygrohypnum styriacum, Plagiothecium ros-sicum, Polytrichum perigoniale, Tortella alpicola and Ulota intermedia) are presented as new for Finland. Cephalozia lacinulata, previously considered to be regional...

The Finnish Biodiversity Information Facility (FinBIF) maintains a national checklist of Finnish species, which is publicly available in the portal Species.fi. The checklist 2022 can be found and uploaded here: https://laji.fi/en/theme/checklist. FinBIF gathers up-to-date information about Finnish species into the checklist, which also functions...

[Turku BioBlitz event results - observations of Turku University campus during one day] The Biodiversity Unit organized a BioBlitz event at the Turku University campus (Finland) and its surroundings areas on 21st-22nd May, 2022. Among 53 participants, seven bryologists observed and collected bryophytes. All observations were either photographed an...

Six species of mosses (Bryophyta: Brachythecium udum, Lewinskya fastigiata, L. elegans, Polytrichastrum altaicum, P. septentrionale, Tortella densa) and two of liverworts (Marchantiophyta: Scapania parvifolia and Tritomaria excecta) are presented as new for Finland. One species, Brachythecium laetum, is removed from the Finnish checklist. New recor...

The Nordic Bryological Society held its Annual meeting and excursion from 5 to 9 August 2019 in Sodankylä, Kittilä and Kolari in northern Finland. The excursion was attended by twenty-one participants. Special emphasis was given to boreal aapa mires and their Sphagnum species. A multitude of Sphagnum species typical to the area was encountered. Als...

Two edible, cultivable mushroom species of the family Strophariaceae, Kuehneromyces mutabilis (sheathed woodtuft) and Hypholoma capnoides (conifer tuft), were studied using proton nuclear magnetic resonance metabolomic approach. The variation in the metabolites of the two species and their metabolic behaviour regarding caps and stipes and different...

Five species of mosses (Bryophyta: Oncophorus demetrii, Oncophorus integerrimus, Oxyrrhynchium speciosum, Sphagnum divinum and Sphagnum medium) and one of liverworts (Marchantiophyta: Kurzia trichoclados) are presented as new for Finland. Seligeria calcarea and Seligeria pusilla, previously thought to be regionally extinct from Finland, are reporte...

Ruissalon luonnonsuojeluarvoltaan monimuotoisista metsistä on kertynyt runsaasti tutkimustietoa sammalista, jäkälistä ja kääväkkäistä. Aineistoa on hajallaan museokokoelmissa ja julkaisuissa eikä yhtenäistä suojelutavoitteita palvelevaa kokonaisuutta ole ollut saatavilla. Tämän raportin sammalosioon on kerätty ajantasainen tieto vuoden 2000 jälkeen...

Herbarium specimens are a treasure trove for biochemical studies. However, this implies understanding of the chemical changes during the drying and storage of the specimen. We compared herbarium specimens at different ages and fresh samples of four mushroom species (Kuehneromyces mutabilis, Hypholoma capnoides, Kuehneromyces lignicola, Hypholoma fa...

Guide to multi-use coastal planning in Baltic Sea area.

The effects of plant invasions on plant communities are often assessed at a few sites or in a particular type of habitat, while studies in different habitat types are scarce. We investigated plant communities in the presence and absence of the invasive ornamental herb, Lupinus polyphyllus, in four habitat types: meadow, forest, road verge and waste...
