Some interesting lichenized fungi from old Fraxinus excelsior and Ulmus glabra in Norway, including four new country records
A survey of lichenized and non-lichenized fungi, and bryophytes on old Ulmus glabra and Fraxinus excelsior trees in Norway was undertaken during 2012–2014. In total, 690 (400 elm, 290 ash) trees at 65 sites were surveyed and 675 records of 34 nationally red-listed epiphytic lichenized fungi were made (Nordén et al. 2015). Several species new to Norway were also found, three of which were reported in Nordén et al. (2013), and one in Nordén (2016). Reported here are four additional species as new to Norway, together with data on six rare species for which our findings contribute to the knowledge of their frequency, distribution and ecology. A few Swedish collections of the same species are also mentioned. All material is deposited in herbarium O. Abbreviations: BN = Björn Nordén, JBJ = John Bjarne Jordal.publishedVersio

Rødsporer (Entoloma), underslekt Cyanula i Norge, med fokus på habitat og utbredelse
This is the third paper with results from the Norwegian Entoloma project 2015-2017. An overview is given of the species of Entoloma subgenus Cyanula in Norway. Cyanula includes, among other elements, many grassland fungi. This paper is part of a larger study concerning the European species of the subgenus Cyanula, including a multigene phylogeny that will be published in due course. Furthermore, a monograph with updated tax- onomic revision is recently issued. This paper focuses mainly on the species recorded from Norway with help of ITS DNA barcoding, with reference to recent collections also from Northern Sweden, with extensive notes of their habitat requirements and distribution. Altogether 53 Cyanula species are presented here, with an updated circumscription and naming. More than half of these are reported new to Norway since the start of the Norwegian Entoloma project. Of these, 18 have been described as new during the last three years, largely based on Norwegian material. Four of these are known exclusively from Scandinavia. barcoding, morphology, taxonomy, calcareous grasslands, calcareous forestsRødsporer (Entoloma), underslekt Cyanula i Norge, med fokus på habitat og utbredelseDette er den tredje artikkelen med resultater
fra det norske Entoloma-prosjektet 2015-2017.
Her gir vi en oversikt over rødsporer i underslekt
Cyanula i Norge. Cyanula utgjør en av
de største gruppene av våre beitemarksopper.
Dette er del av en større studie over de europeiske
artene i underslekt Cyanula, som
inkluderer en omfattende fylogenetisk undersøkelseundersøkelse
som snart vil bli publisert, samt en
nylig publisert bok med en oppdatert taksonomisk
revisjon av gruppa. Det foreliggende
arbeidet fokuserer på arter registrert i Norge
ved hjelp av ITS strekkoding. Også en del
nylige, sekvenserte innsamlinger gjort i nordsvenske
fjellområder er inkludert her. Artene
presenteres seksjonsvis, med vekt på data om
habitat-preferanser og utbredelse. Til sammen
53 Cyanula-arter er presentert her, med oppdatert
artsavgrensning og navnsetting. Mer
enn halvparten av disse artene er rapportert
nye for Norge siden starten av det norske
Entoloma-prosjektet. Av disse er 18 beskrevet
som nye for vitenskapen de siste tre årene, i
stor grad basert på norsk materiale. To av
disse er kun kjent fra Norge, og ytterligere to
kun fra Skandinavia.publishedVersio

Contributions to the revision of the genus Entoloma (Basidiomycota, Agaricales) in Europe : six new species from subgenus Cyanula and typification of E. incarnatofuscescens
In anticipation of a phylogenetically revised monograph of Entoloma in Europe, six new species of subgenus Cyanula are described here. Entoloma cistocruentatum is associated with Cistus in Spain, E. dislocatum occurs in montane regions in Catalonia (Spain) and Tuscany (Italy), E. indikon is known from Denmark and three species are mainly distributed in the Nordic countries in Europe: E. calceus , E. perchalybeum and E. praecipuum. Entoloma incarnatofuscescens, from the /Rusticoides clade is neotypified. A fully amended description is given based on molecular evidence, which includes the recently described E. violaceoparkensis and E. klofacianum which became later synonyms.publishedVersio
Molecular and morphological diversity in the /Rhombisporum clade of the genus Entoloma with a note on E. cocles
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 welldifferentiated cheilocystidia, and a wide range of spore shapes varying from rhomboid to five-angled. To fix the concept of the classical species E. rhombisporum, a neotype is designated. Nine species are described as new to science based on the result of nrDNA ITS phylogeny with additional gap coding, and morphological characterization: E. caulocystidiatum, E. lunare, E. pararhombisporum, E. pentagonale, E. perrhombisporum, E. rhombiibericum, E. rhombisporoides, E. sororpratulense, and E. subcuboideum. The ITS sequences of the holotypes of previously described species belonging to the /Rhombisporum clade, viz., E. laurisilvae and E. pratulense have also been generated and are published here for the first time. Since many of the above-mentioned species have been misidentified as E. cocles, it seemed opportune to also study this species and to designate a neotype to fix its current concept. A key including European species is presented. As most of the species are potentially important indicators for threatened grassland communities, the 130 ITS barcodes newly generated for this study may be useful as a reference in conservation and metabarcoding projects.

What Do the First 597 Global Fungal Red List Assessments Tell Us about the Threat Status of Fungi?
Fungal species are not immune to the threats facing animals and plants and are thus also prone to extinction. Yet, until 2015, fungi were nearly absent on the IUCN Red List. Recent efforts to identify fungal species under threat have significantly increased the number of published fungal assessments. The 597 species of fungi published in the 2022-1 IUCN Red List update (21 July 2022) are the basis for the first global review of the extinction risk of fungi and the threats they face. Nearly 50% of the assessed species are threatened, with 10% NT and 9% DD. For regions with a larger number of assessments (i.e., Europe, North America, and South America), subanalyses are provided. Data for lichenized and nonlichenized fungi are also summarized separately. Habitat loss/degradation followed by climate change, invasive species, and pollution are the primary identified threats. Bias in the data is discussed along with knowledge gaps. Suggested actions to address these gaps are provided along with a discussion of the use of assessments to facilitate on-the-ground conservation efforts. A research agenda for conservation mycology to assist in the assessment process and implementation of effective species/habitat management is presented
