Specimen AB#18 (Forgettable Pholiota)

Regrettably I didn't have my own name for this little one. Its title comes from the fact that it is part of a larger group with a LOT of family resemblance and its easy to forget which is which. But I can say for certainty I won't be forgetting this particular fungus. Walking along through the west woods it showed up near the path with a small army of its brothers and sisters.
