 A 2005 study again failed to separate the two species using molecular methods, but reported that the incompatibility demonstrated in mating experiments suggests that the species are distinct.In the fourth edition (1986) of Singer's comprehensive classification of the Agaricales, "G. marginata" is the type species of "Galerina" section "Naucoriopsis", a subdivision first defined by French mycologist Robert Kühner in 1935.It includes small brown-spored mushrooms characterized by cap edges initially curved inwards, fruit bodies resembling "Pholiota" or "Naucoria" and thin-walled, obtuse or acute-ended pleurocystidia that are not rounded at the top.
