It did finally lay down a very light spore print

measurements are 9 -11 × 7.5 -10 um
they were sub globose, with some appearing globose -very few broadly elliptical

I’ll be very curious to know if it shows up again

The stipe base and color…

There doesn’t appear to be any bulb, other than the very small volva.

I don’t have a hypothesis regarding whether the cap might have faded. We’ve had a lot of clouds lately and the specimen was under a shady hemlock, so any light it would have received would probably not have been direct sunlight.

The good news is, since this came up in our yard, I can check the area again in the future for more specimens that might reveal additional information.

Unfortunately, it’s not cooperating with a spore print thus far.

Is the stipe base slightly bulbous or is a bulb utterly lacking?

Does the cap appear to you to have be faded by sunlight from a deeper color? Perhaps orange or red?
