Following publication of the original article [1], the authors reported a problem in the drawing of Rut-C30 chromosome III in Fig. 2b of the original article [1]. The two fragments of chromosome I inserted inside chromosome III should be swapped, and the direction of the fragment containing rim101 and cel1a genes should be inverted. This reversed insertion indicates that at least 2 rearrangements occurred simultaneously, so the possible scenario proposed in Fig. 2c of the original article was inaccurate. The corrected Fig. 2 with modified panels b and c is available in this erratum. The detailed description of Rut-C30 assembly in the Additional file 5 of the original article is correct.

Chromosome maps of T. reesei QM6a and Rut-C30 strains. Chromosome maps of T. reesei QM6a (a) and Rut-C30 and NG14 (b) strains were identified by reassembly of the JGI reference genome using 3C sequencing data for each strain. For Rut-C30 map, the colors of chromosome fragments are consistent with their colors in QM6a map to clearly show chromosomal rearrangements. Some emblematic genes were chosen along the sequence to be used as location markers (list available in Additional file 6). The Rut-C30 85 kb deletion event on chr. VI is shown by the lack of pks1 gene. Centromere locations are shown by restricted width. c Possible scenario (among others) from QM6a to Rut-C30

The authors also noticed two mistakes in chromosome numbering in the description of these translocations. The correct description is

• “The three translocations resulted finally in the right arm of chromosome I (3′ end of scaffold 48 and main fragment of scaffold 5: 1.63 Mb and 442 genes in total), to be swapped with the right arm of chromosome VI (3′ end of scaffold 22: 402 kb and 114 genes). But also in two fragments of chromosome I (one with a fragment of scaffold 4, and the other one with another fragment of scaffold 4, scaffold 49 and a small fragment of scaffold 48) to be inserted head to foot in the middle of the chromosome III (1.13 Mb and 310 genes in total for both fragments).”
