and pallens means "pale."
Common name(s):  Walnut mycena.

Family:   Mycenaceae
Occurrence on wood substrate:  Saprobic; fruiting on
remains of old hickory nuts and walnuts; August to
Dimensions:  Caps 8-15 mm wide; stipes up to 10 cm tall
and 1-1.5 mm thick.   
Cap: Orange to yellow, fading to whitish.

Comments: If not for the distinctive habitat, this small
Mycena could present an identification challenge. It still is
when the nuts are well-decayed. l will admit that for a
website devoted to fungi growing on wood, hickory nuts
might be a bit of a stretch but it's a beautiful and easily
recognized fungus when found growing on these "woody"

Figure 3.The gills are almost distant and the stipe is
typically orangish at the top and yellow below. The yellow
of the caps seemed to fade even during the time I was
photographing the specimens. Photo © Gary Emberger.

Figure 5. This specimen was fruiting on a very small fragment
of hickory nut. If the substrate was not recognized as a piece
of hickory nut, the task of identifying this mushroom would
be much more difficult. Photo © Gary Emberger.
