Observation 12005: Mycena (Pers.) Roussel

When: 2008-10-05

Collection location: Larch Mountain, Multnomah Co., Oregon, USA [Click for map]

Who: Daniel B. Wheeler (Tuberale)

No specimen available

I’m calling this Bolbitius, even though I can’t explain why. It’s way too small (approx. 3mm across cap) to be B. vitanellus (Sunny-side up in Aurora’s Mushrooms Demystified), but otherwise with a flaring white skirtlike cap with yellow prominently umbonate central cap. Gills and stipe white, gills free to adnexed, on well-rotting wood. Did not get spore print.

With white gills?

Don’t think this is a Bolbitius with white gills.

Try Mycena, something like M. aurantiidisca, or M. oregonensis.

Your comment is well-taken, Darvin. I’m not arriving at any likely location with Bolbitius. Will probably repost shortly.
