Observation 15573: Mycena sect. Longisetae A.H. Sm. ex Maas Geest.
When: 2008-09-28
No herbarium specimen

Notes: Get out your reading glasses, you can’t get too much smaller than this!

These tiny mushrooms were found growing on a nut (almost positive it was hickory) on Sept 28th, 2008 in mixed hardwood Central Missouri (Boone Co.) area. The nut is no more than 1.5 cm in diameter. The caps are no larger than 2 mm, it is grey with spikes, the somewhat translucent stalk is 2 cm tall. It appears to grow from a basal disc.

The closest ID I have so far is Mycena capillaris (Arora p.227), but other online sources include the possibilities of adscendens, nucicola, osmundicola, or aciculata.

Whadya think ???

I like the host and the size suggested by Hymenoscyphus fructigenus. However it appears to be cup-shaped and somewhat yellow. Other observers have suggested Mycena aciculata (longiseta) which is described as having a setose grey cap such as the one I found. Here’s a reference from Smith’s 1947 N.A. Species of Mycena:
