Confidence: I'm as sure as I can be.
Notes: Assuming the finder isn't suffering from a remarkable infection, this is a bit out of context. It should have been growing from a granular algal mat on peat or on a well rotted log. However, it has the characteristic darker colour at the top of the stem, and also the stem can just be seen to be minutely pubescent. I am satisfied it isn't an Arrhenia or Omphalina species, some of which can be similar. Alan
