“…Commemorative species names honor a person or event/ expedition. It is common to name a fungus in honor of a person who has made a considerable contribution to the taxonomy of the group of organisms involved in naming or more generally to society (e.g., Annabella australiensis, Daldinia hawksworthii, Hysterium barrianum, Malmidea attenboroughii, Phaeosphaeria erikssonii, Phoma cavalliniana, Verticillium lindauianum) (Shoemaker and Babcock 1989;Braun and Dick 2002;Boehm et al 2009;Pažoutová et al 2013;Fryar et al 2019;Guzow-Krzemińska et al 2019). In some cases, especially in genera with many species, it is often difficult to find descriptive or geography-based names, and in such cases species names may involve random combinations of letters, so-called nonsense species names.…”

Biodiversity loss from disturbances caused by human activities means that species are disappearing at an ever increasing rate. The high number of species that have yet to be described have generated extreme crisis to the taxonomist. Therefore, more than in any other era, effective ways to discover and delimitate species are needed. This paper reviews the historically foremost approaches used to delimit species in Ascomycota, the most speciose phylum of Fungi. These include morphological, biological, and phylogenetic species concepts. We argue that a single property to delineate species boundaries has various defects and each species concept comes with its own advantages and disadvantages. Recently the rate of species discovery has increased because of the advancement of phylogenetic approaches. However, traditional phylogenetic methods with few gene regions lack species-level resolution, and do not allow unambiguous conclusions. We detail the processes that affect gene tree heterogeneity, which acts as barriers to delimiting species boundaries in classical low-rank phylogenies. So far, limited insights were given to the DNA-based methodologies to establish well-supported boundaries among fungal species. In addition to reviewing concepts and methodologies used to delimit species, we present a case study. We applied different species delimitation methods to understand species boundaries in the plant pathogenic and cryptic genus Phyllosticta (Dothideomycetes, Botryosphaeriales). Several DNA-based methods over-split the taxa while in some methods several taxa fall into a single species. These problems can be resolved by using multiple loci and coalescence-based methods. Further, we discuss integrative approaches that are crucial for understanding species boundaries within Ascomycota and provide several examples for ideal and pragmatic approaches of species delimitation.

“…New fungi can be found almost anywhere, from the rocks of Antarctica, to the dung of sheep, the nests of leaf‐cutting ants, sand dunes and even in the air of basements (Crous, Schumacher, et al, 2019; Crous, Wingfield, et al, 2019; Hyde et al, 2019; Rodrigues, 2019). They occur in terrestrial habitats but also in water, such as Annabella australiensis and Kamalomyces mangrovei growing on decaying wood in mangroves (Fryar et al., 2019; Hyde et al, 2019). Numerous new species of fungi, as well as undescribed higher taxonomic ranks, are also discovered each year from environmental samples (e.g., Tedersoo, Bahram, & Puusepp, 2017).…”

“…However, based on environmental studies, we know that Leotiomycetes, such as the psychrophilic Pseudogymnoascus (Rosa et al, 2019) and the mycorrhizal symbiont of moss, Rhizoscyphus, are dominant members of polar environments (de Hoog et al, 2005;Bridge and Spooner, 2012;Rosa et al, 2019). Culture-based studies have isolated Leotiomycetes from marine (Baral and Rämä 2015;Fryar et al, 2019) and a multitude of freshwater aquatic environments (Baschien et al, 2013;Tsui et al, 2016). The so-called Dark Septate Endophytes, most of which are Leotiomycetes, can be dominant in Alpine ecosystems.…”
