Observation 188933: Mycena pura (Pers.) P. Kumm.
When: 2014-11-08
No herbarium specimen

Notes: The spore print appeared white/creamy to my eye. Under the microscope at 400x it appeared light yellow.

This single small mushroom was growing from the ground out of general mixed hardwood and pine woods. There was white mycelium inches away but did not appear connected to it. When I dug it up, it was rooted and I saw no mycelium.

The cap is just at 1 cm across. The stem is 4-6 times longer than the cap size.

This mushroom is pink. The stem is translucent pink, lighter at the base. The gills are pink but lighter at the edges and the cap is pink and had a velvety texture.

I crushed the base of the stem and it smelled like chlorophyll, like chewing on grass blades.

The gills are wide spaced with a shorter intermediate gill at the outer edge, see photos.

The habitat was woodland, growing in the litter of the forest floor. Surrounded by Short-leaf pine, Sweet Gum and other hardwoods.

This keyed out in the Mycena family. However, I don’t think it is Mycena due to the cap shape and cap surface texture.

I am taking a wild guess at Hygrocybe.

Recognized by sight: Growing on the ground. Really looks like Mycena pura.
Based on microscopic features: The spore shape is within the range of Mycena pura. Compare with these Mycena pura spores: http://cemachampi.blogs.sudouest.fr/...
Also check pileipellis, lamellar trama, cheilocystidia and pleurocystidia.
Based on chemical features: Hygrocybe / Gliophorus would lack an odor.

Melzer’s

My local or your local?

I live in a state where I would probably be treated very badly if I were caught with some form of choral hydrate. At the same time, in this state I could pollute and poison thousands and that would be ok.

It’s not worth the risk for me to get some unless I can do it legally.

It’s hard to understand why Melzer’s could not be sold by one of the scientific supply houses in small quantities. I don’t think you can recover choral hydrate once it’s been mixed with iodines.

The doc didn’t say much just showed great alarm at being asked.

Not an option. I tried talking to my Dr about helping me get some, did not go over well.

Melzer’s would sort out Mycena from other candidates in a hurry.

Thanks for additional information

Thanks A. Rockefeller for the additional information and suggestions.

I’ve only recently learned to measure and photograph the spore. Hopefully, by the time I find this again I will become proficient checking other aspects microscopically.

Thanks for the comments. I will further tomorrow.

However, MushroomExpert shows Mycena pura as having long almost cylindrical spore. The spore shown in the photos are not shaped like that.

As for taste, radish to me means hot. Chewing grass is not hot or spicy.

The stouter

stature and reported “chlorophyll” odor (which I interpreted as radishy), are what made me think of pura. I don’t think Atheniella are ever this stout.

formerly Mycena adonis

I think a good example species

would be Mycena pura, one of the pinker forms of which looks rather like this observation

Mycena example species?

Mycena is the first genus I considered, but it looked to me like the convex cap and surface texture of the cap was not correct for Mycena. Do you know species of Mycena with this combination of color, translucence, size and convex cap?
