Justification
In N. Macedonia, only a few specimens of Galerina tibiicystis have been recorded from a single locality, in a peat bog with the moss Sphagnum. These types of habitats are rare in the country, and they are found at altitudes above 1,600 m, and none of them are protected. On account of the rather small area covered by peat bogs in the country, which are the primary habitats of this species, the number of anticipated specimens does not exceed 200. Considering the latter along with the importance of peat bogs in N. Macedonia and overall in Europe, it is proposed for the category of Critically Endangered (CR).
