The distributions of the ITS (A) and LSU (B) sequences of the manually validated strains. The sequences of the same colour belong to the same class. The five biggest classes in green, red, blue and pink represent 3 810, 2 210, 2 064, 1 483, 574 ITS and 4 151, 2 318, 2 247, 1 582, 615 LSU sequences of Sordariomycetes, Eurotiomycetes, Dothideomycetes, Agaricomycetes, and Leotiomycetes, respectively. The sequences in turquoise colour are the ones (1 145 for ITS and 1 279 for LSU) without a class name given in the database. The 3D coordinates of the sequences were computed using fMLC (Vu et al. 2018) to compute a complete similarity matrix and LargeVis (Tang et al. 2016) to calculate the coordinates of the sequences. The sequences were visualized using the rgl package in R (https://r-forge.r-project.org/projects/rgl/).
