Specimen available

Fairly large fruiting in a lawn on the DreamWorks campus. Based on feedback from Darvin DeShazer, I’ve applied the name Bolbitius coprophilus. Arora emphasizes that it grows on dung which this was not, but otherwise it’s a good match. Other authors do not make such an emphasis. See Darvin’s comment for more details.


As promised here’s a better image from the same general lawn area on the following morning.
Not a great shot. I was in a rush. Hopefully I can get some better photos another day.

“The Bolbitius photos you posted this week looks like Bolbitius coprophilus
to me.

It is a good match in Fungi Fimicoli Italici, Watling Vol 3 and Flora
Agaricina Neerlandica Vol 6.

It also grows on straw, manured ground, sod and compost as well as dung.

Good key in Bessette, Bessette & Fischer

Looking at the last three of these books I agree with this id. One interesting thing I’ve noticed is the stipe tends to have a pinkish cast when fresh, but then dries yellowish.
