Observation 117868: Gamundia striatula (Kühner) Raithelh.
When: 2012-10-05
Herbarium specimen reported
0 Sequences

Notes:
A small group of mycenoid mushrooms with a tan radially striated cap with a darker central depression. The long graceful stipe is glabrous and looks “polished”. Found in mixed woods along the Dead River near West Forks, ME. The spores are ellipsoid with a distinct apiculus and the surface appears very subtly roughened as seen with selective focusing under DIC illumination. Spore print is white and the 20 spore average was 6.2 × 3.9 microns, Qm = 1.58.

The apparent surface texture of the spores is very slight and I have not totally ruled out that this is an artifact of internal structure.

I need to read up on Gamundia striatula.

was taken on a glass slide and is relatively strong. Maybe this is a Mycena after all.

While Rhodocybe prints can be very light and not obviously pigmented, they should not ever be white, maybe try scraping the spores into a pile with a razor blade to get a better idea of the color.
