The present paper establishes the dates of availability for works (Imbach, Konrad et Maublanc, Müller, Pilát, Singer), published in 1946 and especially in 1951–1952, in which transfers are made from Psalliota to Agaricus. The author arrived at these dates chiefly by studying the records in archives, correspondence with the publishers and inquiring in libraries, when they received the legal deposit copies. This is of special importance where different authors made the same transfers.
