Observation 4198: Agaricus L.
When: 2007-09-24
No herbarium specimen

Notes: Really funny Agaricus, has anyone seen ones like these before? No idea on these. They are completely dark brown, with very dark brown gills even when young. Very small guys, with caps 1-3 cm in size. Found at the edge of an irrigated lawn, under live oak.

No idea here, kinda weird.

Fresh stuff here, not cupreobrunneus

These were fresh firm buttons, not old or rotten. The caps were cracked quite a bit, so they might have been growing a little dry, but they didn’t look like they were too weird or stressed in the growth. The flesh was firm, and very firm in the stipe, kinda fibrous, like a plant stem. Although the stipe was hollow. They did not show any staining reactions, and there were no bugs.

They looked like these were nice fresh buttons, and this is just the way they look. And yes, the gills were dark brown even in the young caps.

Unfortunately I don’t have these anymore. I looked for them at the end of class, but there was a kinda mad rush, and people were cleaning up kinda quickly. I had brought in about a dozen species, and a large pile of the Lacrymaria, so stuff just got tossed pretty quick. I had my head down on the scope, and by the time I looked up, things were just gone. So, I don’t know where these went.

There was a Ph. D. student there, who is working on a thesis for Agaricus, so hopefully that is were these went…

Agaricus cupreobrunneus?

Did you see any staining reaction? Are you sure the brown gills where on fresh, young caps? In particular was the flesh still firm. I’ve seen that happen with older caps that look young because they never expanded usually due to a sudden weather change or lots of bugs.

Never seen anything like that
