Mycena cinerella Karsten (1879)

This is a small Mycena that is pretty common on conifer needle beds of Sierra Nevada. It can be recognized by the dry, almost waxy appearing pileus. It also has a farinaceous odor, which in my experience is less pronounced than suggested in the literature. Mycena cinerella is one of the myriad of little gray Mycenas that require attention to detail for proper  identification. In this case, the dry pileus is pretty distinctive -- compare to the viscid Mycena vulgaris below.
