Agaricus species

Agaricus species


Glowing cap very thin at edges, with light circle near centre and around edges. Stipe stringy and with a collar. Gills brown and darkening with age. See photo #4. No spore print as spotted in a national forest.


Native rainforest in Volcano National Park beside the Halemaumau Trail in Kileauea caldera. Growing in the duff on the forest floor. Lots of introduced plants in this area too as well as the native Ohia and others.


These mushrooms were glowing beside the trail.

Thanks Mark and Antonio! I agree with Agaricus and I am thinking about subrufescens. I do see that it is very variable in its appearance and although most of the photos I can find on the internet do not match mine, the description does match which is more important. I wish I had thought to smell it and take a little taste to see if it was almond-y at all! It does grow in Hawaii and it does have a ring on the stipe. It does have dark brown gills in maturity. Sounds good!!

I agreed with Argy,it's an agaric for sure and the link Argy's give is(from what i saw in google images)the most probable hipothisys for the id

They really do glow. Definitely an agaric... maybe like Agaricus subrufescens?
