New national and regional biological records for Finland 4. Additions to the knowledge of Finnish aphyllophoroid funga (Basidiomycota)

Byssocorticium efibulatum is reported as new to Finland. New records of following rare or little collected species are presented and notes of their substrates are given: Cristinia gallica, Helicogloea farinacea, Helicogloea lagerheimii, Phlebia femsioeensis, Sistotrema dennisii and Tomentella coerulea. We also list 33 aphyllophoroid fungi as new to some section of the boreal vegetation zone in Finland

Diversity and distribution of Finnish aphyllophoroid and heterobasidioid fungi (Basidiomycota) : An update

Biogeographical and ecological knowledge of aphyllophoroid fungi has increased substantially after the publication of the Finnish aphyllophoroid checklist. In this paper, we describe the occurrence and distributions of both aphyllophoroid and heterobasidioid fungi in Finland. We introduce 13 species new to Finland: Hyphoderma lapponicum, Mycostilla vermiformis, Proterochaete adusta, Pseudotomentella alobata, Pseudoxenasma verrucisporum, Sistotrema subtrigonospermum, Spiculogloea minuta, Tomentella botryoides, Tomentella neobourdotii, Tomentella subtestacea, Tomentella subpilosa, Tulasnella anguifera, and Tulasnella interrogans. Proterochaete and Pseudoxenasma are new genera to Finland. We also present the record of Caudicicola gracilis for only the second time globally. Furthermore, we present 115 new records (locations) of 53 rare or seldom collected species. In addition, we report 96 species considered new to a specific subzone of the boreal forest vegetation zone in Finland. The records contain notes on the substrata, and the ecology and distribution of nationally new species and are briefly discussed.Peer reviewe

Aphyllophoroid funga (Basidiomycota) of Finland : range extensions and records of nationally new and rare species

Knowledge of the Finnish aphyllophoroid funga has increased substantially in recent years. In this article, we present two species new to Finland: Spiculogloea subminuta Hauerslev and Typhula suecica I. Olariaga, G. Corriol, I. Salcedo & K. Hansen, and document Sistotrema luteoviride Kotir. & K.-H. Larss. for the third time globally. We also contribute 50 new records of 33 nationally rare species (with a maximum of ten previous records in Finland) and list 52 regionally new species, found for the first time in a certain subzone of the boreal vegetation zone in Finland. Each record is enclosed and contains notes on the substrate. Furthermore, the ecology of the nationally new species and the distribution of rare species are discussed

Genome sequencing and population genomic analyses provide insights into the adaptive landscape of silver birch

Silver birch (Betula pendula) is a pioneer boreal tree that can be induced to flower within 1 year. Its rapid life cycle, small (440-Mb) genome, and advanced germplasm resources make birch an attractive model for forest biotechnology. We assembled and chromosomally anchored the nuclear genome of an inbred B. pendula individual. Gene duplicates from the paleohexaploid event were enriched for transcriptional regulation, whereas tandem duplicates were overrepresented by environmental responses. Population resequencing of 80 individuals showed effective population size crashes at major points of climatic upheaval. Selective sweeps were enriched among polyploid duplicates encoding key developmental and physiological triggering functions, suggesting that local adaptation has tuned the timing of and cross-talk between fundamental plant processes. Variation around the tightly-linked light response genes PHYC and FRS10 correlated with latitude and longitude and temperature, and with precipitation for PHYC. Similar associations characterized the growth-promoting cytokinin response regulator ARR1, and the wood development genes KAK and MED5A.Peer reviewe

Author Correction: Genome sequencing and population genomic analyses provide insights into the adaptive landscape of silver birch.

In the version of this article initially published, there was a mistake in the calculation of the nucleotide mutation rate per site per generation: 1 × 10−9 mutations per site per generation was used, whereas 9.5 × 10−9 was correct. This error affects the interpretation of population-size changes over time and their possible correspondence with known geological events, as shown in the original Fig. 4 and supporting discussion in the text, as well as details in the Supplementary Note. Neither the data themselves nor any other results are affected. Figure 4 has been revised accordingly. Images of the original and corrected figure panels are shown in the correction notice

Additions to Finnish Aphylloporoid Fungi

A checklist of Finnish aphyllophoroid fungi was published in 2009. After that plenty of knowledge has been accumulated. Here we present all new information including three species new to Finland as well as species new to one or several boreal zone sections in Finland. Amyloathelia amylacea, Tubulicium vermiferum, and Tulasnella danica are reported as new to Finland, together with records of some species that are very rare in the whole of Finland, such as Athelia cystidi- olophora, Brevicellicium exile, Chaetoporellus curvisporus, Melzericium udicola, Phlebia lindtneri, and Postia mappa. In total, 67 aphyllophoroid fungi are listed as new to some sections of the boreal or hemiboreal vegetation zone in Finland; new records have been made in altogether eight sections out of eleven. We accumulated here all records which were not included in the Finnish checklist, including those that have already been published somewhere else. Thus this paper can be used as a supplement to the checklist.peerReviewe
