I haven’t seen a Hymenopellis irl, but the completely smooth, straight upper stipe, lack of a wrinkled disc or incurved cap margin, and thin looking, campanulate caps seem off for Hymenopellis and on for Mycena or Marasmius. M. galericulata can have a radicating stipe, and the other parts look like some photos of M. maculata or metata…

Observation 28192 looks similar, whatever it is.

I’m not 100%

Because of the habitat, but there was tall vegetation, although not dense. Unfortunately I was in a situation where I wasn’t able to spend any time looking for more to identify any possible ring formation. They are widespread in my area, the western cape. It seems very unlikely to be anything else than M. oreades.

The long rooting stipe and woodland habitat seem wrong. Maybe the vegetation was tall? I guess I was basing my identification on the general gestault which differs from typical M. oreades that I have seen. You are familiar with the mushroom and saw it fresh so I will temper my doubts.

the slenderness and rooting stipe

initially threw me off too, though now it seems kind of plausible.

Almost Certainly Marasmius oreades

Mycowalt, I am almost certain that these are Marasmius oreades specimens. I just took a spore print. It’s white. It is a fairly common mushroom in South Africa, and it’s characteristics closely match the description in ‘Mushrooms of South Africa’. What makes you so apprehensive?
