The advantages and disadvantages of giving a valid name to a sequence of DNA detected from environmental specimens is presently a hot debate amongst the mycological community. The idea of using intracellular DNA (“mgDNA”) from environmental samples as holotypes seems at face value, to be a good idea, considering the expansion of knowledge among these ‘dark taxa’ or ‘dark matter fungi’ that it could provide (i.e. sequence based taxa without physical specimens and formal nomenclature). However… 
Problems, Limitations, and Challenges in Species Identification of Ascomycota Members on the Basis of ITS Regions
TLDR
It is determined that ITS-based species identification and comparative analysis with GenBank sequences significantly helps identifying Ascomycota members.
Intragenomic polymorphisms in the ITS region of high-quality genomes of the Hypoxylaceae (Xylariales, Ascomycota)
TLDR
This case study was dedicated to the detection of ITS nrDNA copies in the genomes, in an attempt to explain certain incongruities and apparent mismatches between phenotypes and genotypes that had been observed during previous polyphasic studies.
Predicting global numbers of teleomorphic ascomycetes
TLDR
This paper estimates the species number for sexual ascomycetes based on five different estimation approaches, viz. by numbers of described fungi, by fungus:substrate ratio, by ecological distribution, by meta-DNA barcoding or culture-independent studies and by previous estimates of species in AscomyCota.
Current Insight into Culture-Dependent and Culture-Independent Methods in Discovering Ascomycetous Taxa
TLDR
Culture-based and culture-independent methods in the study of ascomycetous taxa are summarized and currently, naming dark taxa is not recognized by the ICN, thus provisional naming of them is essential.
A multigene phylogeny toward a new phylogenetic classification of Leotiomycetes
TLDR
A phylogeny based on up to 15 concatenated genes across 279 specimens of Leotiomycetes constitutes a framework for enabling future taxonomically targeted studies using deliberate specimen selection, and an ITS gene tree is presented, particularly targeting ex-type specimens of generic type species.
Current insights into fungal species diversity and perspective on naming the environmental DNA sequences of fungi
TLDR
Here, it is proposed to separate the fungal types into physical type based on specimen, genome DNA (gDNA) typebased on complete genome sequence of culturable and uncluturable fungal specimen and digitaltype based on environmental DNA sequence data.
Integrative approaches for species delimitation in Ascomycota
TLDR
It is argued that a single property to delineate species boundaries has various defects and each species concept comes with its own advantages and disadvantages and several examples for ideal and pragmatic approaches of species delimitation are provided.
Elucidation of the life cycle of the endophytic genus Muscodor and its transfer to Induratia in Induratiaceae fam. nov., based on a polyphasic taxonomic approach
TLDR
The phylogeny shows that Muscodor species have affinities to the xylarialean genera Emarcea and Induratia, which is corroborated by the fact that their sexual states produce characteristic apiospores, which allow for the integration of Mus codor in Induratian, i.e. the genus that was historically described first.
Repositories for Taxonomic Data: Where We Are and What is Missing
TLDR
An improved reuse of taxonomic data, including machine-learning-based species identification and delimitation pipelines, requires a cyberspecimen approach—linking data via unique specimen identifiers, and thereby making them findable, accessible, interoperable, and reusable for taxonomic research.
Hidden mycota of pine needles: Molecular signatures from PCR-DGGE and Ribosomal DNA phylogenetic characterization of novel phylotypes
TLDR
A PCR-DGGE based method coupled with rDNA phylogenetic sequence analyses to characterize fungal taxa associated with pine needles provides new insights in hidden fungal diversity that mycologists are possibly ignoring given the discrepancies associated with available methods.

Considerations and consequences of allowing DNA sequence data as types of fungal taxa
TLDR
It is concluded that the acceptance of DNA sequences alone as types of names of taxa, under the terms used in the current proposals, is unnecessary and would not solve the problem of naming putative taxa known only from DNA sequences in a scientifically defensible way.
Effectiveness of ITS and sub-regions as DNA barcode markers for the identification of Basidiomycota (Fungi)
TLDR
This study performed a large-scale analysis of all the available Basidiomycota sequences from GenBank and identified genomic markers that had a superior identification performance than the others and genomic marker that were not indicated for the identification of some genera.
Introducing ribosomal tandem repeat barcoding for fungi
TLDR
Three sets of general primers are presented that allow the amplification of the complete ribosomal operon from the Ribosomal tandem repeats and hope to stimulate the generation of a new comprehensive standard of ribosome reference data with the ultimate aim to close the huge gaps in the authors' reference datasets.
Preliminary notes on dual relevance of ITS sequences and pigments in Hygrocybe taxonomy
TLDR
The results seem to confirm the taxonomic concept of Bresinsky (2008) who proposed the division of the genus Hygrocybe, and further research using DNA markers at the intergeneric level is suggested to revaluate the taxonomy of former HyGrocybe species.
Biological identifications through DNA barcodes
TLDR
It is established that the mitochondrial gene cytochrome c oxidase I (COI) can serve as the core of a global bioidentification system for animals and will provide a reliable, cost–effective and accessible solution to the current problem of species identification.
New light on names and naming of dark taxa
TLDR
Issues relating to the taxonomy and nomenclature of dark taxa are discussed and a number of questions that the mycological community needs to consider before deciding on what system/s to implement are highlighted.
Soil sampling and isolation of extracellular DNA from large amount of starting material suitable for metabarcoding studies
TLDR
New sampling and extraction protocols suitable for DNA metabarcoding analyses targeting soil extracellular DNA, designed to reduce the influence of local heterogeneity by processing a large amount of soil resulting from the mixing of many different cores, are developed.
Fungal diversity notes 491–602: taxonomic and phylogenetic contributions to fungal taxa
TLDR
This is a continuity of a series of taxonomic and phylogenetic papers on the fungi where materials were collected from many countries, examined and described and DNA sequence data is analysed from concatenated datasets to infer phylogenetic relationships and substantiate systematic positions of taxa within appropriate ranks.
