Mycena citrinomarginata  Gillet (1876)

Apparently Mycena citrinomarginata is a fairly variable species with forms that range from yellowish-orange on the cap to pale grayish-yellow. The yellow margin on the are lamellae is fairly pale in the collection above and hasn't been captured well photographically. The long necked, occasionally forked cheilocystidia is quite distinct, although that this feature is variable too. Mycena of Norway has a good treatise on the variations of this species here.
