mycena42's Identifications

This is the photomircroscopy for observation https://www.inaturalist.org/observations/35711937
From Dan Morton: Mycena piceicola is a possibility. The spore size, cheilocystidia shape and size, basidia size, and stipe length align with Mycena piceicola. Ann Goddard recorded on a slip of paper that the collection was found in spruce, hemlock and fir needle duff. Mycena piceicola prefers spruce and sometimes Douglas-fir. MycoQuebec.org states the cap color is sometimes whitish.Cheilocystidia are shaped like those described under Mycena piceicola. Overall Length - 21 - 28.8 µm, width 4.5 - 9 µm

On dead vine maple branch (Acer circinatum). Interestingly, it occurs both on wood and along chains of mycelium (see last two photos), somewhat like the "birds nest" marasmius species in Ecuador. in the HJ Andrews Forest between the 1506 road and Watershed #2. Unburned control. Old growth forest dominated by Pseudotsuga menziesii in the canopy plus Tsuga heterophylla, Thuja plicata and Taxus brevifolia. High moss cover including Hylacomnium splendens and Dicranum and Kindbergia.
