Observation 223443: Gymnopus subsect. Alkalivirentes
When: 2015-11-19
( 671m)

Notes: Gregarious. Singly, but more often in pairs or groups.

White spores. Should be visible in the photos, and I got an extremely faint print on foil.

Growing at the base of a ponderosa pine, but there was a 5 needle pine sapling nearby, along with white fir and incense cedar saplings. Also plenty of oak in the vicinity.


3% KOH on cap. This picture was taken on Nov 22, which is three days after original collection photos.

Looks very close. Stipes are darker in your collection, but otherwise look

very similar to my collection. Wish I would have tried KOH on gills.

Thanks for your help, and for linking your obs to this one. Perhaps someone studying Gymnopus would like a sample of both collections.

Looks like it is turning dark olive green in KOH

Nov 22, 2015. 3% KOH on cap surface. Alan, this didn’t look green to me, but there was definitely a reaction.

KOH color changes work when dry, other times you need fresh mushrooms. Depends on which chemicals are changing color in response to the pH.

No color change with KOH, but sample was mostly dry.

Should color change be apparent even if dry?

Try putting a drop of KOH on the cap

Instant green color?
