- Abstract
Jafnea semitosta is an ascomycete (Pyronemataceae, Pezizales) originating from North America and spreading uncommonly in Europe. Its genome size was measured via flow cytometry of fruiting bodies from five localities in the Czech and Slovak Republic. The nuclear 1 C DNA content was estimated at 3.706 ± 0.011 pg (~3.625 ± 0.011 Gbp) which represents the highest value ever reported for fungi and 100× higher than the average. Generally, the genome inflation in fungi appears to be driven mainly by proliferation of repetitive sequences, but polyploidy should also be considered in further studies on this greatly unexplored topic.
