Summary:
Cortinarius armeniacus and related species. A small group around Cortinarius armeniacus is reviewed. The taxa belong to the subgenus Telamonia, they have a brownish cap and whitish, non-radicating stipe, and grow in spruce forests. Taxa with distinctly coloured flesh or stipe are explicitly excluded. Despite the bewildering variety within even such a circumscribed group, most of the finds in Sweden turn out to be either C. armeniacus Fr. ss latu, or C. dilutus Fr. Several collections of a red-brown to date-brown form of C. armeniacus are reported, and it is argued that this taxon is in reality identical to C. triformis Fr. ss Mos., Marchand. The form is in fact mentioned by Fries [1830] as a variety of C. armeniacus under the name Ag. badius Schum.
As regards C. melleo-pallens (Fr.) Lge, the author has several collections that might be attributed to this taxon, but it is argued that there are very few, if any, characters that can be unambiguously used to distinguish it from armeniacus. A review of the common literature shows that authors tend to assign more or less identical characters to the two. Although it is possible that Lange has found a pale variety of C. triformis Fr. ss Fr nec auct, as witnessed by his icon, it is certainly not the taxon referenced by most authors. Fries' own triformis (including his form melleopallens) is probably a rare species in Sweden.

Summary:
The paper attempts to clarify the specific variety in the group containing
C. paragaudis Fr. and C. hæmatochelis Bull.:Fr.
An analysis of twelve collections from Central Sweden is presented,
and it is shown that the material can be split roughly into two groups,
separated mainly by spore size. Finally, a new species,
resembling a C. paragaudis with a white veil, is described.

Summary:
A new Cortinarius from subalpine Betula forests.
A new Cortinarius (Telamonia) with a reddening veil is described. The species appears related to C. spilomeus Fr. var. depauperatus Lge, but differs in an initially greyish veil with a faint olivaceous hue. Lange's taxon is promoted to specific rank and moved to Telamonia, where the two species form a natural group, to which one should possibly add C. heterosporus Bres.

Summary:
A new look at Cortinars in the Bread-&-Butter group.
A difficult group of Cortinarii may be designated "bread-&-butter" due to their deceptively commonplace look and ubiquitous presence. A restricted set of such taxa is examined: they are all middle-sized Telamoniæ with a white veil, brownish cap and pale stipe, growing with conifers. New varieties of C. tortuosus (Fr.:Fr.)Fr. and C. biformis Fr. are described. Taxa illustrated by colour photographs:

Summary:
Bread-&-Butter Cortinars, part II.
This paper continues the theme of difficult Cortinarii that may be designated "bread-&-butter" due to their deceptively commonplace look and ubiquitous presence. The most frequently encountered Telamoniæ with a white veil, brownish cap, and a pale stipe seem to be adequately presented in modern literature. Not all of these trivially looking species are common, however. In this instalment a few uncommon ones are described and illustrated in colour:

Summary:
Cortinarii with a red veil.
A key is given to Scandinavian species of Cortinarius with a reddish
(red or brown-red to vinaceous) veil, and four uncommon and interesting species
are described and illustrated in colour.
The key, which is partly based on M. Moser's well-known key of red-veiled Cortinarii
(Moser 1965), concentrates on the subgenus Telamonia.

After a comparison of the Northern and Southern Hemispheres
in terms of biotopes, mycorrhiza, and foraying conditions in general,
a number of taxonomic problems at the infra- and suprageneric level of
Cortinarius are noted.
The following species are illustrated in colour:

Summary:
Two of the finds are described and illustrated in colour photographs:
C. bovinus Fr. is interpreted according to M. Moser (as opposed to ss Lange,
a taxon which is considered identical to C. bulbosus Fr.). The second species,
C. cæsiostramineus, differs from a similar taxon, also found in the locality,
by a (sometimes strong) blue coloration on the stipe, a more fibrillose cap,
lack of a bitter taste (except possibly as an after-taste), a fruity smell,
and slightly shorter spores. The latter taxon, identified as C. amarescens Mos.,
is sometimes regarded as a synonym, but should be separated at least by varietal rank.
Finally a beautifully orange-coloured species akin to C. callisteus Fr. is depicted,
differing from the former by colour, by (almost) white gills when undeveloped,
lack of odor, and markedly stronger fluorescence in UV light. It might be recognised
as a form of C. tophaceoides Mos. ined., which however has the typical stearine smell
of callisteus, or possibly as Flammula abrupta Fr. ss Melot.
The following species are illustrated by colour photos:

A list of Cortinarius finds is presented from an extremely productive,

— download pdf.
Summary
The taxonomy and phylogeny of sect. Multiformes (Cortinarius, subgen. Phlegmacium) are presented. The present circumscription of the section is supported by molecular data and morphological features. The taxonomy is complex and many taxa are quite new and little known. Two new species are described. Altogether ten European species are recognized: C. multiformis, C. talimultiformis, C. frondosomultiformis sp. nov., C. rufoallutus, C. talus, C. melleicarneus, C. caesiolamellatus, C. caesiophylloides, C. pallidirimosus and C. armenicorius sp. nov.
The ten recognized species are (i) more or less well-supported phylogenetically, but (ii) with a fairly low morphological differentiation. The species differs by over 1% in ITS DNA from sister taxa, and each species pair show a morphological differentiation, though in most cases with overlapping characters. For instance, most species have overlapping variation in size and shape of the spores, and less than half of the species have formerly been recognized in morphological studies.
Résumé
Cortinarius sous-genre Phlegmacium section Multiformes en Europe.
On présente la taxinomie et la phylogénie de la section Multiformes (Cortinarius, sous-genre Phlegmacium). La délimitation actuelle de la section est étayée par des données moléculaires et des caractères morphologiques. La taxinomie est compliquée et beaucoup d'espèces sont tout à fait nouvelles et peu connues. On reconnait en tout 10 espèces européennes : C. multiformis, C. talimultiformis, C. frondosomultiformis sp. nov., C. rufoallutus, C. talus, C. melleocarneus, C. caesiolamellatus, C. caesiophylloides, C. pallidirimosus et C. armenicorius sp. nov.
Ces 10 espèces sont (i) plus ou moins bien identifiées au plan phylogénétique, toutefois (ii) assez peu différenciées morphologiquement. Les espèces diffèrent des espèces sœurs à raison de plus de 1% quant à leur ITS d'ADN, et chaque paire d'espèces présente certes une différenciation morphologique, mais avec des chevauchements. C'est ainsi que les dimensions et la forme des spores de la plupart des espèces sont très semblables, et moins de la moitié des espèces présentées ici étaient autrefois distinguées dans les études morphologiques.

Pour caractériser la section, on peut aussi recourir à des caractères morphologiques (par exemple les changements de couleur de la chair à l'air) et à des réactions macrochimiques (par exemple de la chair au lugol). En l'état actuel des connaissances, la section Purpurascentes englobe 5 espèces, dont on présente des photos, des descriptions et une clé de détermination.

Summary
New data on affinities within Cortinariaceæ.
In recent times a flurry of papers have reported on molecular-biological studies of taxa in this family. After a review of the concepts and methods involved, the results are summarised for a number of groups (clades) with emphasis on Cortinarius ss. lato, and their impact on current taxonomy is assessed. It is recognised that any attempt at this diverse and complex group must include extensive material from the Southern Hemisphere. The practical consequences for European taxonomy are likely to be limited, however.

It seems to be one of the most common members of subg. Telamonia
in oligotrophic spruce forests of the northern taiga region.

A fantastic season on Öland, SE Sweden — A report with emphasis on Phlegmacium (Cortinarius).
Due to an unusually rainy year 1996 in SE Sweden, some dry localities on the calcareous island of Öland exhibited an unprecedented development of Cortinarius subgenus Phlegmacium. This paper presents two of the most favourable localities and a species list. The list includes five taxa not previously published from Sweden and ten that have merely 1 to 4 known localities in the country, occurring mainly on Öland. Of the taxa, 24 are rare to very rare in Sweden and most of these are listed in the Swedish red list of fungi.
The localities are characterised by dry, extensively grazed areas displaying a mosaic of shrubs, mainly of Corylus and Juniperus. Between the shrubs are dry grassland communities (Avenetum) with dominating grasses and herbs such as Avena pratensis, Helianthemum nummularium, and Thymus serpyllifolia.
The localities are exposed to a very warm local climate and have a long continuity of mixed Corylus/Juniperus populations with sparse occurrences of Quercus, Betula, etc. These factors, along with the extremely calcareous soil, are responsible for the very diverse fungus flora, including more southerly species as well as species that normally occur in deciduous woodlands.
The habitats are extremely vulnerable and under serious threat. Local authorities are urged to protect the remains of this type of eco-system and land-use. The vegetation, including the fungi, should be investigated further. During just a few visits 1995-1996, the best locality produced 150 recorded species of Basidiomycetes, of which 28 are in the Swedish red list of rare and threatened fungi. Most probably the type of fungal community found on the sites is unique in Europe. Further, a most valuable subject for investigation would be to study the association between mycorrhizal species and various species of shrubs and herbs, including Helianthemum spp.

Summary:
Lepiota cortinarius found in Sweden.
The first confirmed records of Lepiota cortinarius J.E. Lange from Sweden are reported. They
were collected in Picea forests in the boreal zone, indicating that the species is perhaps less
continental than formerly believed.

Determining threshold values for barcoding fungi: lessons from Cortinarius (Basidiomycota), a highly diverse and widespread ectomycorrhizal genus. FEMS Microbiology Ecology 92(4).
Abstract:
Different distance-based threshold selection approaches were used to assess and compare use of the internal transcribed spacer (ITS) region to distinguish among 901 Cortinarius species represented by >3000 collections. Sources of error associated with genetic markers and selection approaches were explored and evaluated using MOTUs from genus and lineage based-alignments. Our study indicates that 1%Ð2% more species can be distinguished by using the full-length ITS
barcode as compared to either the ITS1 or ITS2 regions alone. Optimal threshold values for different picking approaches and genetic marker lengths inferred from a subset of species containing major lineages ranged from 97.0% to 99.5% sequence.

Abstract:
Abstract Seven commonly used Friesian names of
Cortinarius sect. Anomali, Spilomei, and Bolares are
discussed. Neotypes for C. anomalus, C. spilomeus, and
C. bolaris, as well as epitypes for C. albocyaneus,
C. caninus, and C. tabularis are proposed. The distinction of
these six species is supported by both morphological and
rDNA internal transcribed spacer (ITS) data, whereas
C. azureus, as currently typified, is considered as a synonym
of C. anomalus, but could also be considered as nomen
dubium. Barcodes (ITS) and morphological descriptions
based on materials from a broad geographical area in Europe
are provided for each species. Furthermore, two new species,
C. jonimitchelliae and C. pastoralis, from northern Europe are described. The latter is proposed to accommodate
C. anomalus subsp. campestris, which has been described
from treeless habitats with Helianthemum. Our study reveals
that the subsp. campestris is not an intraspecific variety of
C. anomalus, but an own species close to C. caninus, and
has a much wider distribution and host range than earlier
thought. An identification key for the species/sections included
here is provided.

Abstract:
A new species of Pseudobaeospora collected in New Zealand is described; it is characterized, among
other parameters, by the presence of pleurocystidioid elements, a micro morphological feature never
known before to this genus. Descriptions and photos of macro- and microscopic features are presented.

Abstract:
The taxonomy and phylogeny of sect. Aureocistophili (Cortinarius, subgen. Phlegmacium)
are presented. The section is well circumscribed by molecular data and morphological features.
We identify nine species in the section, two of which are undescribed. The study is based largely
on data from our own collections; however, in three cases (C. aureocistophilus, C. kytoevuorii,
and C. inusitatus) descriptions follow the protologues. In the study we generated nineteen new
sequences, which serve as the base for a phylogram covering the section and other relevant portions
of the subgenus. Species of section Aureocistophili are widespread all over Europe, from
Fennoscandia to the Mediterranean. They grow on soils of varied acidity and with various coniferous
and deciduous trees. Although more material is needed for some species, we publish here a
provisional key of the section.

Abstract:
A section-based taxonomy of Cortinarius, covering large parts of the temperate North and South Hemispheres,
is presented. Thirty-seven previously described sections are reviewed, while another forty-two sections
are proposed as new or as new combinations. Twenty additional clades are recovered but not formally described.
Furthermore, six new or combined species names are introduced, and one species is neotypified. The structure is
supported by morphological characters and molecular evidence, based on two (nrITS and nrLSU) and four (nrITS,
nrLSU, rpb1 and rpb2) loci datasets and analysed by Maximum Likelihood methods (PhyML, RAxML). Altogether
789 Cortinarius samples were included in the study.

Schmidt-Stohn G, Saar G, Soop K, Brandrud TE, Dima B. 2020. Cortinarius subgenus Phlegmacium subsection Varii in Europe. Journal des JEC 22: 27-49.
Abstract:
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 except for C. variiformis s.
str. and C. variosimilis, whose descriptions follow the protologues, too. In the study we generated
eighteen new sequences, which serve as the base for a phylogram covering the subsection.
Species of subsect. Varii are characterised by their strict mycorrhizal associations, at least in
Europe, with a wide variety of mycorrhizal hosts apparently mainly or exclusively growing on
basic soils. Although more material is needed for some species, we publish here a provisional key
of the subsection.

Abstract:
Cortinarius section Xenosmatae, originally based on solely morphological characters, was subsequently shown to contain
phylogenetically distantly related species. The type species C. xenosma is a singleton, and this study aims to revise the other
members of the section using combined molecular (nrDNA ITS and LSU) and morphological data. Based on phylogenetic
analyses using RAxML, PhyML and Bayesian Inference and additional morphological features one new species (C.
paraxenosma) and one new section (sect. Olorinati) are proposed. Furthermore sect. Carbonelli is extended and emended
to include two former members of sect. Xenosmatae. A key to the species in New Zealand with xenosmatoid morphology is
provided.

Abstract:
Cortinarius section Phlegmacioides in Sweden.
An interesting group of Cortinarius section Phlegmacioides is reviewed in the light of Swedish
findings and recent molecular studies. A number of rare species in the section are described:
C. sobrius, C. balteaticlavatus, C. balteatibulbosus, and forms of the more common
C. pseudon¾vosus and C. balteatocumatilis are briefly discussed. A new species, C.
aff. decumbens, possessing a unique macromorphology in the section, is described in the
hope that it may trigger additional findings. A phylogram of the section and colour plates of
several phenotypic forms are presented. (In Swedish).

Abstract:
Cortinarius is a species-rich ectomycorrhizal genus containing taxa that exhibit agaricoid or sequestrate
basidiome morphologies. In New Zealand, one of the most recognizable and common
Cortinarius species is the purple sequestrate fungus, C. porphyroideus. We used genome skimming
of the almost 100-y-old type specimen from C. porphyroideus to obtain the nuc rDNA internal
transcribed spacer region ITS1-5.8S-ITS2 (ITS barcode) and partial nuc rDNA 28S (28S) sequences.
The phylogenetic position of C. porphyroideus was established, and we found that it represents a rarely
collected species. Purple sequestrate Cortinarius comprise multiple cryptic species in several lineages.
We describe four new species of Cortinarius with strong morphological similarity to C. porphyroideus:
Cortinarius diaphorus, C. minorisporus, C. purpureocapitatus, and C. violaceocystidiatus. Based on
molecular evidence, Thaxterogaster viola is recognized as Cortinarius violaceovolvatus var. viola.
These species are associated with Nothofagus (southern beech) and have very similar morphology
to C. porphyroideus but are all phylogenetically distinct based on molecular data.
