Notes:
[PNW Key Council Foray. Found by Danny Miller.]

Found in Root Rot Forest (which is a mixed forest). This is a single mushroom collection—the darker one on the photos. (I’ve forgotten where the other mushroom came from. The photos were taken very late in the night.) No notes about the odor.

[Added 2017/04/30] The second mushroom was collected by Kem Luther, his photo added below. Unofortunately, this one was not preserved.

The pigment is very strong. I’ve never seen a Mycena that colored the water so much when revived.

There are two marginate Calodontes species recognized in this country, and often confused: pelianthina and rutilantiformis. Smith distinguished them by two characters: (1) presence of yellow on the stipe of rutilantiformis, (2) the width of spores—up to 3.5 microns in pelianthina, mostly above 4 microns in rutilantiformis. Well, here we have yellow on the stem, and spores that are almost all 3.5 microns wide; only a few reach 4 microns.
