I understand the “shake” test, but how does Prunulus fit? What defines a Prunulus?

perhaps not a mycena

despite the very conical cap. your shake test results may point elsewhere. a mycologist far more seasoned than I used this as the magic mirror to differentiate between Marasmius and Mycena spp. (essentially: Marasmius endure, Mycena succumb). I suppose now’s a good a time as any to put his hocus pocus to the masses for a little peer review.

@cs: it is an award worthy little mycena. Any idea what kind it might be?

@myxomop: semi-tough = it would pass your test but is not so tough that the stem can’t be torn without too much effort, fibers would be dangling. It was just that it looked so fragile and was tougher than it looked. But yes it would pass the test.

Congratulations, Adam!

Also, thanks to Twizzler (I think) who started this tradition. Which doesn’t actually happen every week, but you get the picture.

awfully charismatic

but how tough is semi-tough? would it pass a shake test?*

.* = the shake test:

1. hold between thumb and forefinger ~half-way up stem
2. shake
3. observe for breakage or resilience
