A correlation between the extracellular laccase activity (estimated by a drop test using ABTS) and the presence of a dark pigmented zone in the pairing of different Trametes (Coriolus) versicolor dikaryons in vitro was studied. Al together 24 dikaryotic strains from different substrates and distant localities of three European countries were paired to each other and the pairings were checked for the presence of dark pigment in the contact zone. Using the \2 test, a positive correlation between the laccase activity and the presence of pigment was found.
