Inocybe seems likely

If so, this is the largest species I’ve seen so far!

I also collected some new material, found within 5 ft of this collection. I will add the new collection as a separate observation, hopefully comparable to this observation.

thanks Alan

for the tip.
My camera allows me to change the AE Metering and the choices are average, center-weighted, or spot.
I would assume a better choice in that setting would be the average setting, “entire scene is used to calculate exposure”
Also, would it help to shoot with an ISO-100 speed in overcast situations where there isn’t enough light?

For those wondering what the hell I was on about in my first comment, I guess ya just had to be there.

what the duece?

“what the duece?”

Aperture is too open making the depth of field too narrow. A very small amount of flash would give better colors.

ok, it’s late and I’m fried but…
