In this study, we investigate the phylogeny and taxonomy of the /Camptori clade sensu Soop et al. (2019a). Based on combined nrDNA ITS phylogenetic, morphological, and ecological analyses, the clade includes six species in Europe, four of which are described here as new to science: Cortinarius malavalii, C. marklundii, C. violaceoserrulatus, and C....

A combined morphological and molecular genetic study of the European species within the /Rhombisporum clade of the genus Entoloma reveals a high species diversity. This group comprises typical grassland species with pronounced and well-differentiated cheilocystidia, and a wide range of spore shapes varying from rhomboid to five-angled. To fix the c...

The taxonomy and phylogeny of the new subsect. Varii (Cortinarius, subgen. Phlegmacium) are presented. The subsection is well circumscribed by molecular data and to some degree also on morphological features. We identify seven species in the subsection, six of them occurring in Europe. The study is mainly based on data from our own collections exce...

A group of Swedish and Norwegian mycologists together with Russian mycologists were studying the funga in Western Siberia around the city of Tomsk, as part of the Russian national mycological foray, arranged every second year. Of particular interest for the Scandinavian participants were fungi growing with conifers that do not naturally occur in Sc...
Technical Report

This report is about a proposal of management plan for Berg plant and animal life protection area at Berg Museum, Kragerø, Norway. A total of 34 red-listed insect species from the area, mostly beetles, are listed.
Article
Cortinarius subgen. Cortinarius, comprising the C. violaceus complex, is treated based on Nordic material. With its micromorphological and pigment characters, the subgenus occupies a rather isolated position. The blue and rose vacuolar pigments are not found elsewhere in the genus Cortinarius, but the trichodermal pileipellis structure shows possib...
Article
The effects of liming on soft-water aquatic macrophytes are reviewed, based on data from the many limed lakes and rivers in Sweden and Norway. Liming usually leads to a re-establishment of acidification-sensitive species such as Fontinalis spp., Myriophyllum alterniflorum and Potamogeton spp. Most sensitive species have a critical level at pH ca. 5...
Article
On a large scale, the acidified River Bjerkreim, southwestern Norway, has been treated with lime since the autumn 1996. During the Atlantic salmon (Salmon salar) smolting period pH has been above 6.2 and LAl concentrations below 10 g L-l. Before 1996, only the western part of the watercourse harboured acid-sensitive species, such as the Atlantic sa...
Article
The effects of enhanced nitrogen availability in formerly nitrogen-limited forest ecosystems on the species diversity of sporocarps and mycorrhizas of ectomycorrhizal (EM) fungi were studied in a nitrogen addition experiment at Gårdsjön, an oligotrophic Norway spruce forest in SW Sweden. The experiments were performed by comparing plots that had re...
Article
The growth of J. bulbosus was investigated in a cultivation experiment with a two-way factorial design for liming and reacidification. The growth of J. bulbosus on limed sediment in a reacidified water layer clearly differed from the growth in the other treatments. Dry weight was approximately five times higher after a growth period of five months...

The taxonomy of Cortinarius subgen. Phlegmacium sect. Phlegmacioides (= Variecolores) in Europe is emended to include 18 species, classified in three subsections: Subsect. Variecolores: C. variecolor (emended to include C. nemorensis sensu R. Henry, Mos.), C. violaceomaculatus, C. spadicellus (= C. amigochrous), C. largus (= C. nemorensis sensu J.E...
Article
Enhancement of the atmospheric N deposition is a serious threat for the structure and function of ecosystems. Here we evaluate the ecological effects of excess N with respect to changes in vegetation and soil biota in a series of experiments along a N gradient across Europe. The aim of this project (NITREX: N saturation EXperiments) is to assess th...
Article
Changes in the ectomycorrhizal fungus flora were studied in connection with nitrogen addition and removal experiments in a Norway spruce forest at Gårdsjön, W Sweden during a 5-year period. The above-ground ectomycorrhizal fruit body production was recorded from permanent transect plots, and the below-ground mycorrhizal fine-roots density and morph...

Article
Full-text available
The taxonomy of Cortinarius subgen. Phlegmacium sect. Phlegmacium in Europe is emended to include 17 species, classified in three subsections: Subsect. Triumphantes: C. saginus ( = C. subvalidus), C. triumphans (=C. crocolitus). C. varius (here neotypified). C. variiformis ( = C luteocingulatus), C. tiliae sp. nov., C. pini sp. nov. and C. norrland...
Article
The taxonomy of Cortinarius section Phlegmacium in Europe is treated, including 18 taxa, with emphasis on an analysis of character variation and differentiation as a tool for species delimitation and the selection of diagnostic characters. Based on the character differentiation between closely related taxa, spore size, veil structure, veil pigment...
Article
Rapid expansion of Juncus bulbosus L. and the concomitant suppression of isoetid plant species has often been observed in acidifying soft water lakes in Western Europe. Experimental studies have shown that this mass development of J.bulbosus was caused by changes in the carbon and nitrogen budgets in these ecosystems. Acidification leads to tempora...
Article
The effects of liming on the aquatic macrophyte vegetation have been investigated in S and SW Norway. In the western part of the study area, Juncus bulbosus was considerably more frequent in the limed than in the unlimed lakes, whilst in the eastern part there were no such differences, and the J. bulbosus populations were generally not so vital. In...
Article
Changes in the ectomycorrhizal fungus flora in connection with increased, ambient and decreased levels of nitrogen deposition were studied in transect plots at Gårdsjön, Sweden, during 1990–1993 as part of the NITREX programme. From 1991, ammonium nitrate was added (about 35 kg N ha−1 year−1) to catchment G2 NITREX, while at adjacent catchment G1 R...
Article
Transplantation experiments for the study of aquatic macrophyte growth and vitality were carried out in the HUMEX Lake Skjervatjern. Plants (preferentially indigenous) were transplanted to plastic pots in the acid-treated (A) basin and the control (B) basin. During the first phase of the experiments in 1991-1992, shortly after start of acidificatio...
Article
Isoetes-Lobelia clear water lakes in an ultraoligotrophic area of south-western Norway were studied. Most lakes in the area are acidified, with a vegetation dominated by small isoetids such as Lobelia dortmanna L., Littorella uniflora (L.) Aschers. and Isoetes lacustris L. After liming, however, dense stands of Juncus bulbosus L. often have develop...

The taxonomy and ecology of Cortinarius subgenus Myxacium section Colliniti in Fennoscandia is treated. Most species of this group have their optima in oligotrophic habitats, and play an important role in upper boreal and Arctic-alpine regions. Variation in spore morphology is subjected to numerical treatment. Relevant nomenclatural types and proto...

Starting from the morphology based taxonomy of Entoloma, reflected in Fungi Europei vol. 5a and Nordic Fungi, an attempt is made through barcoding of European species, including type specimens, to come to a phylogenetically based species concept.
