Fig. 3From: Formal description of sequence-based voucherless Fungi: promises and pitfalls, and how to resolve themNumber of species-level clusters computed from pyrosequencing ITS reads belonging to a “single” species, the basidiolichen former Cora inversa; up to 99% of the observed variation is due to sequencing errors (after Lücking et al. 2014). The same data cluster as a single species-level clade in multiple-alignment-based phylogenetic analysis (see Fig. 4).Back to article page
