The lack of available type material and associated absence of multiple locus sequence data has complicated identification of these fungi. The aim of this study was to clarify the identity of the laccate Ganoderma species occurring in Finland by inferring a phylogeny using DNA sequences from available boreal-temperate material. DNA from Finnish isolates together with an older G. lucidum isolate originating from the United Kingdom was sequenced, and the morphological features of the Finnish specimens were examined. The phylogenetic analysis of the internal transcribed spacer region (ITS), the elongation factor 1-α (tef1), RNA polymerase II subunit (rpb2), and partial β-tubulin (β-tub) genes revealed that the G. lucidum isolate from the United Kingdom did not fall within a well-supported clade with other G. lucidum sequences or related species. The Finnish isolates were closely related to the G. tsugae lineage in tef1, rpb2, and β-tub phylogenies. However, G. tsugae appears morphologically distinct from the Finnish material. The results suggest that G. tsugae, or a species phylogenetically closely related to it, may occur in Finland. But further investigation into the relationship between G. tsugae and G. lucidum from Europe will be needed to clarify the identity of the laccate Ganoderma species in Finland.","PeriodicalId":18779,"journal":{"name":"Mycologia","volume":"3 1","pages":"1-17"},"PeriodicalIF":2.8,"publicationDate":"2024-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142199276","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Given that morphological characteristics and existing molecular markers are not sufficient for distinguishing among species, we expanded the genomic resources for these sections to support research in biosystematics and species diagnostics. Whole genome assemblies for 22 strains were generated, including the first genomes from section <i>Infectoriae</i> or <i>Pseudoalternaria</i> strains sampled from Canada, which significantly increases the number of publicly released genomes, particularly for section <i>Pseudoalternaria</i>. We performed comprehensive phylogenomic analyses of all available genomes (n = 39) and present the first robust phylogeny for these taxa. The segregation of the two sections was strongly supported by genomewide data, and multiple lineages were detected within each section. We then provide an overview of the biosystematics of these groups by analyzing two standard molecular markers from the largest sample of section <i>Infectoriae</i> and <i>Pseudoalternaria</i> strains studied to date. The patterns of relative diversity suggest that, in many cases, multiple species described based on minor morphological differences may actually represent different strains of the same species.

Given the complexity associated with concurrently culturing diverse fungal species, developing practical methods for preserving as many species as possible for future research is vital. The widely accepted best practice for preserving fungal tissue is the use of cryogenic biobanking at -165 C, allowing for the preservation and documentation of stable genetic lineages, thus enabling long-term diversity-centered research. Despite the extensive literature on fungal cryopreservation, substantial barriers remain for implementation of cryogenic biobanks in smaller mycological laboratories. In this work, we present practical considerations for the establishment of a fungal culture biobank, as well as provide evidence for the viability of 61 fungal genera in cryogenic storage.
