Observation 58334: Agaricus arvensis Schaeff.

When: 2010-11-08

Collection location: San Mateo, California, USA [Click for map]

Who: Tom (LanLord)

No specimen available

Growing in wood chips beneath a small redwood.

These smelled strongly sweet and anise like. They had the overall Augustus look to them, but weren’t as large as other Augs I have found.

They stained yellow very lightly when cut or bruised.

Their stems were very long and twisted/contorted.

Sullivan’s comments up there, note also the lack of distinct shaggy scales on the stipe (unlike augustus), and lack of distinct appressed scales on the cap.

Also, check out that cogwheel annulus!

What would be the selling point for Arvensis?

I’ve not seen this species before (that I am aware of, but Agaricus is a difficult genus for me because I usually can’t tell the aromas apart).

I’d be interested in knowing what makes this appear as that species?
