Descriptions are presented of thirteen species and five varieties of Galerina, provisionally described as new by the Dutch mycologist J.J. Barkman in 1969 and 1970. The descriptions and illustrations are based on the original descriptive notes and our own study of microscopic characters. The study was hampered by the poor condition of most exsiccata. Nevertheless, the majority of the provisional taxa could be identified as belonging to species described before. Four provisional species could not be identified with certainty, but they show so much resemblance to existing species that there is no reason to consider them as new taxa. One provisional species, G. anomala, is strongly deviating from other Galerina species and does probably not belong to that genus. Its identity remains unknown. In addition, our study revealed useful information on the taxonomic significance and variability of some diagnostic characters in Galerina.
