Figures of merit and statistics for detecting faulty species identification with DNA barcodes: A case study in Ramaria and related fungal genera

DNA barcoding can identify biological species and provides an important tool in diverse applications, such as conserving species and identifying pathogens, among many others. If combined with statistical tests, DNA barcoding can focus taxonomic scrutiny onto anomalous species identifications based on morphological features. Accordingly, we put nonparametric tests into a taxonomic context to answer questions about our sequence dataset of the formal fungal barcode, the nuclear ribosomal internal transcribed spacer (ITS). For example, does DNA barcoding concur with annotated species identifications significantly better if expert taxonomists produced the annotations? Does species assignment improve significantly if sequences are restricted to lengths greater than 500 bp? Both questions require a figure of merit to measure of the accuracy of species identification, typically provided by the probability of correct identification (PCI). Many articles on DNA barcoding use variants of PCI to measure the accuracy of species identification, but do not provide the variants with names, and the absence of explicit names hinders the recognition that the different variants are not comparable from study to study. We provide four variant PCIs with a name and show that for fixed data they follow systematic inequalities. Despite custom, therefore, their comparison is at a minimum problematic. Some popular PCI variants are particularly vulnerable to errors in species annotation, insensitive to improvements in a barcoding pipeline, and unable to predict identification accuracy as a database grows, making them unsuitable for many purposes. Generally, the Fractional PCI has the best properties as a figure of merit for species identification. The fungal genus Ramaria provides unusual taxonomic difficulties. As a case study, it shows that a good taxonomic background can be combined with the pertinent summary statistics of molecular results to improve the identification of doubtful samples, linking both disciplines synergistically.

“…However, C. stercoreus is distinguished by the absence of striae in the peridium, inconspicuous emplacement, woolly tomentum, endoperidium with platinum bright colour, spores not exceeding 31 μm in length, and spore walls less than 2.5 μm in thickness. Cyathus lignilantanae has basidiomata above 7 mm in height, internal wall with platinum bright colour, peridioles with 2–2.5 × 1.5–2 mm, spores smaller than 25.5 μm in length and 17 μm in width, and with thin walls not reaching 2 μm ( Martín et al 2015 ).…”

“…Barcoding sequences also help in identification of the species Tulostoma brumale in some collections, when a brown ring zone around the mouth is absent or not clearly defined, or T. simulans, which also is described as having a brown mouth zone (Jeppson et al, 2017). However, as indicated by many authors (Schoch et al, 2012;Jeppson et al, 2013;Martín et al, 2015;Sousa et al, 2017), the ITS marker alone is not enough to infer the phylogenetic relationship among species, and it is necessary to study at least two or three markers to clearly delimitate the taxa (such as Tef 1a used in the analyses by Jeppson et al (2017), RPB2, or translation elongation factor 1-alpha). Moreover, in our study more collections should be found and studied to define Tulostoma sp.…”

The genus Tulostoma Pers. (Order Agaricales; Basidiomycota) is characterized by a globose spore-sac, where the spores are formed, attached onto a stipe; they are known commonly as stalked puffballs. The sporesac is formed by the peridium that envelopes the gleba; when spores are mature, they are released via an opening found on the apical part of the sac called a mouth or stoma that can be tubular, circular, or elliptical; fibrillose or fimbriate; or a simple crevice. The current genus was initially divided into two sections: Eutylostoma and Schizostoma (Fischer, 1900, 1933; Petri, 1909; Fries, 1921), which are differentiated by mouth morphology. Pouzar (1958) offered a more precise classification based on the morphology and mode of opening of the exoperidium, as well as the morphology of the mouth and stipe, proposing four sections: Brumalia, with tubular mouth; Poculata, with mouth fibrillose; Fimbriata, with fimbriate mouth; and Volvulata, with irregular mouth. Wright (1987) supplemented Pouzar's classification with primary and secondary micromorphological characteristics. The primary characteristics are the endoperidium form, size, and color; exoperidium color, persistence, and decay; mouth form; and spore size and ornamentation. Secondary characteristics are stipe size, and color and morphology of stipe surface; thickness of capillitium hyphae; and morphology of capillitium transverse septa. In Wright's classification two subgenera are included: Tulostoma Pers. and Lacerostoma J. E. Wright, encompassing 137 species worldwide. As pointed out by Cunningham (1925), Moreno et al. (1992) considered that this genus consists of a taxonomic complex, since some characters are not always easy to differentiate. The genus has been studied in various areas of Europe, Asia Minor, and Africa. In the work of Kreisel (2001), 28 species were cited in Europe, 14 in Asia Minor, and 38 in Africa. In the Mediterranean area, Calonge et al. (2007) described 22 species for Spain, while Tkalčec et al. (2005) and Sesli and Denchev (2008) reported only five species in Croatia and Turkey. In Macedonia, based on morphological identification, Karadelev and Rusevska (2009) confirmed four species: Tulostoma brumale Pers., T. fimbriatum Fr., T. melanocyclum Bres., and T. squamosum (J.F. Gmel) Pers. (Table). Wright (1987) reported, for the first and only time, T. caespitosum Trab. Molecular analysis based on the internal transcribed spacers (ITS) of nuclear ribosomal DNA (nrDNA), accepted as the DNA barcode for fungi (Schoch et al., 2012), provides valuable information for species identification. Recently, Jeppson et al. (2017) demonstrated that the ITS region is very useful to discriminate Tulostoma species in Europe; in this paper the barcode sequence was obtained Abstract: With the aim of clarifying the number of Tulostoma species in Macedonia, and to verify some previous collections, molecular analyses were carried out on four morphologically identified species collected in different habitats (at the edges of oak or juniper forests, pine ...
