“…Other species form the order Agaricales were found to have similar chromosome numbers: e.g. Agaricus bisporus (n = 13, Sonnenberg et al , 1996), Coprinopsis cinerea (n = 13, Muraguchi et al , 2003), Pleurotus ostreatus (n = 11, Larraya et al , 1999) or Laccaria montana (n = 9, Mueller et al , 1993). Given that our genetic map reached marker saturation and covers 93% of the scaffold-level assembly, the presence of additional chromosomes is highly unlikely.…”
